Breast thread lifting is a minimally invasive technique for correcting mild to moderate ptosis, offering aesthetic enhancement with reduced morbidity compared to traditional mastopexy. This review examines the anatomical underpinnings, clinical indications, technical nuances and limitations of breast thread lifting. The breast's fascial architecture, particularly the role of Cooper's ligaments and the retromammary space, critically influences thread trajectory and vector planning. Classification systems assist in proper patient selection, highlighting the suitability of thread lifts for Grades I-II ptosis with minimal skin excess. Advances in ultrasonography have improved preoperative planning, thread placement accuracy and postoperative monitoring. Various thread types, including PDO, PLLA, PCL and Silhouette Soft, offer different lifting capacities and collagen-stimulatory properties, necessitating tailored material selection. Although thread lifts offer immediate improvements, their transient nature necessitates careful patient counseling to manage expectations regarding durability and potential maintenance sessions. Innovative techniques, including clavicular anchoring and multi-level subdermal scaffolding, have expanded the procedural repertoire. Despite certain limitations, breast thread lifting remains a valuable tool within the aesthetic surgeon's armamentarium, particularly for patients seeking minimally invasive options with shortened recovery periods and favorable psychosocial outcomes. Future developments are expected to further enhance safety, reproducibility and long-term results. A clinical study was conducted to determine the effect of nasal valve lift treatment using absorbable, polylactic acid, self-retaining cone threads (Silhouette Soft) in patients with nasal valve stenosis. Sixty patients (n = 60) were included in this prospective study which was performed from January 2015 until December 2018, 19 patients dropped out due to noncompliance. Initially, participants were divided into two equal groups. One was treated by nasal valve lift only, the other additionally received turbinoplasty. A visual analog scale (VAS) was used to rate the sense of nasal ventilation. Patients' satisfaction was examined by a categorical scale, preoperatively, after 1 week, and after 1, 6, 12, 18, and 24 months. For statistical analysis, an univariant variance analysis was conducted to test the significance of differences in nasal breathing within one group at different points of postoperative controls, with the statistical significance set at p < 0.05. Moreover, the two groups were compared with each other regarding results of the categorical scale. After surgical treatment, an improvement is reported by all participants. Average VAS scores were significantly lower between preoperative and every postoperative rating. Although a decline in the effect of breathing improvement is recognizable as threads are dissolved, patients' satisfaction in improvement of nasal breathing is persistent in most cases, even at long-term observation. Overall, these results demonstrate that valve lift is an effective method to treat patients with nasal valve stenosis. Increased demand for rejuvenation of the aging face has led to the evolution of various plastic surgery techniques. This study was conducted to evaluate the surgical efficacy and outcomes of the absorbable suture suspension system related to eyebrow, midface, mandibular, and neck lifting. In this prospective review chart clinical study, a total of 193 patients were included in the study from January 2016 to May 2017. All participants underwent thread lifting using the Proma Happy Lift double needle and Silhouette Soft threads. The patients were followed up for first week and first, third, and sixth month after lifting surgery. Outcomes were assessed by two surgeons and patients based on the GAIS score. A total of 193 patients (mean age: 52.22 ± 11.74 year, range: 25-89), 23 (11.9%) men and 170 (88.1%) women, were included in the study. The most common sites for the face lifting surgery were the jawline (46.1%), midface (33.7%), eyebrows (12.4%), and neck (7.8%). The level of satisfaction increased from 94% in the first week after surgery to 99% in the sixth month after surgery for patients, increased from 94% to 99% for surgeon 1, and increased from 83% to 98% for surgeon 2. The results showed that the level of satisfaction of patients and surgeons increased over time. These results demonstrated that facial rejuvenation thread lift with Proma Happy Lift double needle and Silhouette Soft threads is a being cosmetically more acceptance, safe, and effective procedure associated with minor complications.

Skin quality is a multidimensional concept encompassing four emergent perceptual categories (EPCs): firmness, surface evenness, tone evenness, and glow. Microfocused Ultrasound with Visualization (MFU-V; Ulthera System) is a non-invasive device FDA-cleared for lifting and tightening of the skin in specific areas. Through the generation of thermal coagulation points at defined depths, MFU-V initiates neocollagenesis and elastin remodeling, which may support improvements in features related to overall skin quality. To evaluate clinical and preclinical evidence for the impact of MFU-V across the four EPCs of skin quality, including firmness, surface evenness, tone evenness, and glow. A structured narrative review was conducted across PubMed, Google Scholar, and Cochrane databases. Of 703 unique records screened, 67 studies met inclusion criteria. Eligible studies evaluated MFU-V, alone or in combination, reporting outcomes mapped to one or more EPCs of skin quality. MFU-V demonstrated consistent improvements in firmness (n = 52 studies), including elasticity and tautness, with sustained effects beyond 6 months. Improvements in surface evenness (n = 35) included wrinkle reduction, pore refinement, and scar remodeling. Effects on tone evenness (n = 4) were observed in melasma and erythema models, with good tolerance in Fitzpatrick skin types III-VI. Glow (n = 4) was indirectly supported by improved texture and structure. Combination protocols involving MFU-V and fillers or neuromodulators reported positive outcomes. Adverse events were rare and transient. MFU-V provides a safe and versatile platform for enhancing multiple aspects of skin quality. Its effects are well supported in firmness and texture, with emerging evidence for tone and glow. The integration of EPC-based outcomes may inform individualized treatment planning and future research. Both micro-focused ultrasound (MFU) and monopolar radiofrequency (MRF) interventions are relatively safe and well tolerated as a non-invasive approach to achieve rejuvenating effects, with patients reporting limited adverse effects. However, MRF uses an electrical current which can induce heating in metal, potentially causing burns or thermal injury in the skin or tissue around the implant, whereas MFU delivers focused high-energy ultrasound, which does not induce electrical currents in metal. This report describes the case of a 28-year-old Thai male, who received titanium implants in the mandible bone, the mandible chin, the maxillary bone and the zygoma bone, seven years before. Because of his wish for a more sculpted and lifted facial appearance, the patient was treated with Ulthera Legacy in 2021 and with Ulthera Prime in 2024. With Ulthera Prime, visualization has significantly improved, which decreased the need to skip areas, leading to improved, more consistent results. This case study suggests that Ulthera Prime could be an option for skin firming and lifting effects for people with facial implants. Further research will be needed to corroborate this finding in a larger population. Ultrasound energy is delivered to the dermal and subdermal tissue to induce thermal injury, leading to collagen remodeling and resulting in lifting and tightening of the skin. Ulthera and Sofwave are two Food and Drug Administration-approved systems that have demonstrated clinically significant results in providing eyebrow, submental, and neck lift and minimizing facial fine lines and wrinkles. Patient selection and management of expectations are important components to a successful treatment process. Both devices boast high patient satisfaction rates, minimal recovery time, and excellent safety profile. Ultrasound technology is an effective, nonsurgical option for facial rejuvenation. Microfocused ultrasound with visualization (MFU-V) is a recently developed technology that improves the laxity of the skin due to its capacity of precise focal heating of the dermis and deep layers, consequently inducing neocollagenesis and elastin remodeling. This case series aimed to assess the efficacy of MFU-V in improving skin laxity, leading to the slimming of the lower third of the face in women who desired to naturally improve the shape of their faces. Four women between 29 and 36 years were submitted to a specific protocol with 4-MHz - 4.5-mm and 7-MHz - 3.0-mm transducers (Ulthera®) at the buccinators region in one session, and patients were evaluated after 180 days. GAIS (Global Aesthetic Improvement Scale) was assessed through standardized photographs (D0 vs D180). All subjects perceived the slimming of the face after 180 days, as well as the improvement of skin laxity and contour. The practitioner and all the patients were highly satisfied with the results. The assessment of GAIS (D0 vs D180) resulted in score 3 (very improved) for three participants, and score 2 (improved) for one woman. All the patients classified pain experienced during the procedure as mild to moderate. We reported a technique that uses microfocused ultrasound with visualization leading to the slimming of the lower third of the face. Further systematic studies should be performed to understand the mechanism underneath the results and to maximize its performance. The aging of facial structures depends on genetic, anatomic, chronologic, and environmental factors that affect the skin and underlying tissues. Microfocused ultrasound with visualization (MFU-V) has emerged as a safe and effective treatment for skin laxity. As the nutritional status may contribute to skin aging, it would be interesting to evaluate whether different dietary patterns can also influence the response to MFU-V treatment for skin laxity. The aim of this study is to compare the outcome of MFU-V therapy between omnivore and vegan patients. Twenty-seven vegan and twenty-seven omnivorous women who underwent MFU-V treatment for laxity of lower face and neck were enrolled. The clinical outcome was evaluated using the FLR (Facial Laxity Rating) scale after 3 and 6 months from treatment. At baseline, no significant differences were found in terms of FLR scale in both treated sites. After 3 months, reduction in FLR scale was significantly lower for vegans both on face (P = .04) and neck (P = .004). At 6 months, vegan patients had a worse clinical outcome on lower face (P = .001) and neck (P < .001). The present study suggests that a vegan diet may negatively influence the outcome of a MFU-V treatment. The changes in the mid face and lower face are among the most prominent features of the aging process. Intense focused ultrasound, known as the Ulthera System (Ulthera Inc., Mesa, AZ, USA), was designed to correct this process. It employs micro-focused ultrasound to cause discrete focal heating of the dermis and stimulates neocollagenesis and elastin remodeling. This study enrolled 50 adult patients of Indian ethnicity who opted for correction of mid face and lower face sagging by Ulthera. The subjects were treated using Ulthera 3.0 mm probes which targets deep dermis and 4.5 mm, which targets the superficial muscular aponeurotic system. All patients were evaluated for allergic reactions and side effects like scarring and nerve/muscle dysfunction. Investigators Global Aesthetic Improvement Scales Scores and Patients Global Aesthetic Improvement Scales Scores were used for analysis at 30 days, 60 days, 3 months, 6 months, and 1 year. Photographs were taken for detailed facial evaluation. Patients were asked to fill a self-assessment questionnaire. At the end of 6 months, improvements in mid face and lower face were reported in 93% patients by blinded reviewers and 85% patients found the results to be satisfactory. The same results were maintained at the end of 1 year. Our study showed that substantial results can be achieved in overall aesthetic improvement of sagging of mid face an

This randomized, parallel-group clinical trial aimed to evaluate the one-year clinical performance of the Beautibond Xtreme adhesive system (Shofu Inc., Kyoto, Japan) applied with different bonding strategies in Class I and Class II posterior restorations. A total of 22 patients (14 female and 8 male, aged ≥18 years) requiring restorative treatment provided 152 teeth with Class I or Class II carious lesions or defective restorations. Restorations were randomly assigned to six groups, including two control groups (Class I and II using the total-etch technique) and four test groups (Class I and II using either the self-etch technique or selective enamel etching). All restorations were performed using Beautibond Xtreme adhesive combined with Beautifill LS composite resin. Clinical performance was assessed at baseline, six months, and one year using modified United States Public Health Service (USPHS) criteria, including anatomic form, marginal adaptation, marginal discoloration, color match, surface texture, secondary caries, postoperative sensitivity, and retention. Randomization was performed with a computer-generated sequence, and two calibrated, blinded examiners (Kappa = 0.84) conducted all evaluations. No significant changes were observed in anatomic form, color match, surface texture, secondary caries, postoperative sensitivity, or retention over time in any group (p>0.05). However, restorations performed using the self-etch technique showed significant deterioration in marginal adaptation and marginal discoloration from baseline to six months and one year (p<0.05). Significant differences were also observed when comparing these restorations to the total-etch and selective enamel etching groups (p<0.05). The Beautibond Xtreme adhesive system demonstrated better clinical performance when applied with total-etch or selective enamel etching techniques compared to the self-etch mode for both Class I and Class II restorations after one year of follow-up. Laser-assisted liposuction using 1470-nm radial fiber emits light energy preferentially absorbed by water, yielding a rapid and localized contouring and tightening effect, with minimal scarring. When collected under appropriate conditions, extracted fat samples can be exploited as autologous filling material in liposculpturing procedures. To assess the 6-month contouring efficacy of 1470 radial fiber-assisted liposuction and the volumetric enhancement effect of the harvested tissue in facial fat grafting. Twenty subjects underwent liposuction (BeautiFill, Alma Lasers, Inc.) of lower abdominal or outer thigh fat. In seven subjects, harvested samples were grafted into facial regions. Treatment safety, body weight, blinded evaluator-assessed aesthetic improvements, and subject-rated satisfaction were monitored for 6 months. Abdominal and facial fat thickness were assessed by magnetic resonance imaging (n = 5) within 3 months of treatment. One-month posttreatment, most subjects ranked improvements good/excellent (88%) and skin tightening satisfactory/very satisfactory (92%), with >70% of subjects providing similar scores 6-month posttreatment. Blinded evaluators noted improved/very much improved aesthetic appearance (87%). Harvested tissue injected as a facial filler (21.0 ± 5.2 ml) led to a 0.63 ± 0.12 mm increase in facial fat thickness, observed by MRI, within 3 months. Six months postfilling, the majority of subjects (83%) were satisfied with the outcome. All procedures were well-tolerated. A single 1470 nm radial fiber-assisted abdominal and thigh liposuction session provided for effective and durable reduction of adipose tissue deposits, with appreciable skin tightening and aesthetic improvements. The gentle harvesting method yielded viable filler material, which was well-retained in facial regions for up to 6 months. The primeval evaluation of the properties of composite resins with different compositions that impact clinical behavior is very important in guiding use in clinical settings. The aim of this study was to evaluate color stability (ΔE) and Knoop microhardness (KHN) of composite resins containing different compositions. Forty-five disks were made composite resins: Filtek Z350 XT/3MESPE and Beautifill II/SHOFU and divided into 3 subgroups: Control - immersed in artificial saliva; OB - brushing with Oral B 3D White; CT - brushing with Colgate Total 12. The OB and CT groups had the disks brushed daily with 120 cycles after immersion in coffee solution (10 min) for a period of 30 days. ΔE and KHN was obtained at baseline and after the treatments. Data were analyzed ANOVA and Tukey tests (p < 0.05). ANOVA revealed significant differences for ΔE and KHN. ΔE: the highest mean was observed in Beautifil II composite resin group, which differed significantly from Z350 group. For the Beautifil II, the treatments were significantly different from each other. For the Z350, the control group showed significant differences in relation to OB e CT groups. KHN: the highest mean was observed in Z350 group, which differed significantly from Beautifil II group. For Z350, the control group showed significant differences in relation to OB e CT groups. For Beautifil II, the treatments did not differ significantly among themselves. The composite resin containing fluoride in the composition showed higher color alteration (ΔE) and lower Knoop microhardness (KHN), thus demonstrating that composition is an important factor in the clinical performance of esthetic restorative materials.

Following Nonablative fractional Fraxel laser (NAFL), a well-established treatment for skin rejuvenation, immediate post-procedural care is essential to address any potential complications and accelerate the healing process. To evaluate the efficacy and patient satisfaction of a topical skincare regimen containing vitamin C, vitamin E, and ferulic acid-CE Ferulic serum (CEF) following NAFL treatment in the Chinese population. In this randomized, investigator-blinded, split-face, controlled trial, patients with mild-to-moderate facial photodamage were randomized to receive CEF treatment on one side of the face and normal saline (NS) on the other side immediately after the NAFL procedure and daily during the 7-day follow-up. The primary endpoint was the change from baseline in erythema score on Day 7, with key secondary endpoints including changes from baseline in erythema index (EI), melanin index (MI), transepidermal water loss, skin hydration, skin sebum content, scabbing, edema, overall patient satisfaction, and post-procedure pain. In total, 50 patients (female 45/50) were enrolled in this study, with a mean age of 31.6 years. The mean change from baseline in erythema score was significantly lower on the CEF side than on the NS side on Day 7 post-NAFL treatment (0.04 ± 0.40 vs. 0.18 ± 0.48, p = 0.011). The CEF side also exhibited improved changes in EI, MI, and skin hydration, as well as higher overall satisfaction and less pain compared with the NS side. Applying CEF after NAFL treatment reduced erythema progression, maintained skin hydration, and promoted the healing process compared with NS. Chinese Clinical Trial Registry: ChiCTR2300069246. Multicentric Castleman's disease (MCD) with cutaneous involvement has rarely been discussed in dermatologic literature, with few reports. Cutaneous lesions in MCD may induce deep scars, causing a significant impact in the daily life of the patients. The treatment of Castleman's disease (CD) is usually a challenge, especially in case of cutaneous involvement. We report the case of a 35-year-old Caucasian man with a 3-year-old history of MCD with cutaneous involvement that we treated with a combined therapy characterized by siltuximab and 1,927 nm fractional laser. The patient showed a therapeutic response, characterized by a reduction of systemic symptoms and cutaneous manifestations. We believe that the combination of siltuximab and 1,927 nm fractional laser might have a synergistic beneficial role in patients with cutaneous iMCD and maximize esthetic outcomes. Anyway, additional evidence is needed to validate our findings. Microbotox technique, intradermal injection of microdroplets of botulinum toxin, is a favorable rejuvenation approach in subjects who prefer more natural appearance. To determine the best injection techniques (dosage, concentration, as well as number and location of injection points), efficacy and side effects of this innovative technique for facial rejuvenation. We conducted a search in Pubmed, Embase, Web of Science, and Google Scholar databases from conception until October 2021 with keywords "microbotox" OR "mesobotox" OR "intradermal injection" AND "botulinum toxin" AND "rejuvenation" AND "wrinkle" AND "face-lift." Twenty articles were included in this review article. Different types of formulation including onabotulinum toxin A (OBA), abobotulinum toxin A (ABO), and incobotulinum toxin A (IBA) were used. The most used concentrations were 10-20 u/cc of OBA. Number of injection points varied from 4 (forehead and periorbital areas) to 999 (entire face) with 2 mm to 2 cm apart. Adjuvant treatment modalities were cross-linked hyaluronic acid, intense pulsed laser, and Fraxel laser. Most studies reported the initial results appeared after 5-14 days of procedure, lasting for nearly 3-6 months. Microbotox is an efficient and attractive method for facial rejuvenation, mid-lower face-lifting, and fine wrinkles reduction in forehead, periocular, and cheek regions, especially in younger-aged subjects. Furthermore, it is a suitable treatment for neck rejuvenation and recontouring of lower mandibular border, particularly in older subjects with marked skin laxity. The Fraxel Dual laser system (Solta Medical, Inc., Bothell, WA) contains a 1,550 and 1,927 nm wavelength single handpiece with different indications for each wavelength. To discuss treatment setting recommendations and best practices for select on-label and investigational applications of the 1,550 and 1,927 nm dual laser system. Eight board-certified dermatologists with 10 or more years of experience with the 1,550 and 1,927 nm laser system completed an online survey about their clinical experience with the system and then participated in a roundtable to share clinical perspectives and best practices for using the laser system. For all Fitzpatrick skin types, treatment recommendations were described for selected approved indications for the 1,550 and 1,927 nm laser system, including both lasers in combination. Treatment recommendations were also reached for investigational applications with the 1,550 nm laser and 1,927 nm laser. Best practices for using the lasers during the treatment session to achieve optimal outcomes and decrease the post-treatment recovery time were compiled. The 1,550 and 1,927 nm dual laser system is effective for a wide range of aesthetic and therapeutic applications, on and off the face and across all Fitzpatrick skin types. Following our survey, we can appreciate that a variety of laser platforms exist to rejuvenate the skin by resurfacing the outer layer of the skin as well as heating the lower layers of the dermis. Based on reliable clinical effectiveness and a limited side effect profile, we can confirm that nonablative fractionated technologies greatly improve the appearance of lentigines, rhytids; eliminate sun damage, attenuate scarring due to acne and other causes; and treat hyperpigmentation. The Fraxel (Solta Medical) laser system delivers pulses across a wide range of density and energy levels. We determined that when increasing the pulse energy this led to an increase in thermolysis microzone depth and width without damaging the surrounding tissue. Due to its performance and various clinical applications, Fraxel laser can be optimally considered to be the gold standard for skin rejuvenation. Sebaceous hyperplasia (SH) is a common skin presentation in adults. Due to their unwanted yellow papular appearance, patients may desire their removal. Although several treatment modalities have been reported, the full range and efficacy of options are unclear. To determine the efficacy of laser modalities in the treatment of SH. The authors will also specifically assess the efficacy, recurrence rate and side effect profile of SH treatment with Er:YAG wavelength using a variable long pulsed (VLP) Er:YAG laser (SP Dynamis Fotona laser, Ljubljana, Slovenia) Methods & Materials: A comprehensive literature search was performed through PubMed, EMBASE, and Web of Science, using the search terms [(sebaceous hyperplasia)] and [(laser[s], Er:Yag, Er:Glass, Fraxel, CO2, PDL, Pulse dye laser, Diode, Xe-Cl, Excimer, Argon, KTP, Ruby, Alexandrite or Nd:YAG)]. The search yielded a total of 119 results and 8 were identified as relevant to this reviewResults: Pulse dye laser (PDL) provides a wide range of treatment results from complete reduction to flattening of the SH without significant adverse events; recurrence rates were unreported. Short PDL showed faster treatment response than long PDL. CO2 laser can produce considerable positive cosmetic outcomes with marked clinical improvement without any recurrence, but significant adverse effects have been reported. The 1450-nm diode laser has been described to produce good (75%) clinical improvement and lesion shrinkage ranging from 50% to greater than 75% without lasting adverse effects. In

Riehl's melanosis is a hyperpigmentation disorder that has a significant psychological and social impact on individuals. In the past 10 years, new categories have been developed, raising questions about how to classify Riehl's melanosis. The mechanism of this disease remains unclear, although the type IV hypersensitivity response caused by allergic sensitization, as well as genetic, ultraviolet radiation, and autoimmune factors, is to blame. Clinical manifestation, dermoscopy, reflectance confocal microscopy, patch/photopatch testing, histopathology, and a novel multimodality skin imaging system have been used for the diagnosis. A variety of therapies including topical skin-lightening agents, oral tranexamic acid, glycyrrhizin compound, chemical peels, and lasers and light therapies (intense pulsed light, 1064-nm Q-Switched Nd: YAG laser, 755-nm PicoWay laser, nonablative 1927-nm fractional thulium fiber laser, new pulsed-type microneedling radiofrequency), with improved effectiveness. The latest findings on possible biomarkers and their relationship to other autoimmune diseases were also summarized. Until recently, quality-switched nanosecond lasers have been the workhorse lasers in treating pigmented lesions. However, the recently commercialized picosecond lasers have provided physicians with a novel method to manage pigmented lesions. Most recently, the first picosecond laser with a 730-nm wavelength was developed to specifically target melanin and melanocytes. We report on two Asian patients with freckles, lentigines, and melasma who were successfully treated with a novel 730-nm Ti:Sapphire picosecond laser (Picoway®; Syneron Candela, Corp). The clinical outcome was measured by the global percent of clearance, which was evaluated by blinded observers by comparing the post-treatment photographs with the baseline photographs. In both patients, a significant pigmentary reduction was achieved with only one treatment session. In both patients, the treatments were well tolerated with minimal discomfort even without topical anesthesia. No post-inflammatory hyperpigmentation or repigmentation was observed until the 6-week follow-up. The pigmentary conditions treated included freckles, lentigines, and melasma. Both subjects showed clinical improvement, with the best results observed for the treatment of freckles such that 95% of the lesions achieved excellent response (75-94% lightening). The results of this case report indicate that a novel 730-nm Ti:Sapphire picosecond laser may be effective and safe in treating pigmentary disorders in darker-skinned patients. Therefore, further well-designed, prospective clinical trials are warranted to establish the potential of 730-nm picosecond lasers and determine the optimal treatment parameters in comparison to existing laser and light modalities. Lasers Surg. Med. © 2020 Wiley Periodicals LLC. Pigmentation is one of the few major characteristics according to which scars are evaluated. Data on the treatment of the hyperpigmented component of scars are sparse. The authors aimed at evaluating the efficacy of the fractional 1,064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) picosecond laser in the treatment of the hyperpigmented component of scars. Sixteen patients with hyperpigmented scars underwent 3 to 8 treatment sessions at 3- to 6-week intervals with the 1,064-nm Nd:YAG picosecond laser (PicoWay, Candela, Resolve handpiece). The treatment response was evaluated by 2 noninvolved dermatologists on a global assessment scale (GAS) of 1 to 4. A Mexameter quantitatively evaluated the melanin content of the scar before and after laser treatments. The average GAS score of the 2 noninvolved dermatologists was 3.31 ± 0.57. The patients assessed their level of tolerance as good or excellent and their satisfaction level as moderate or high. The Mexameter showed that the melanin index decreased considerably (by 39.11 ± 11.58%) in all patients after treatment. The fractionated nonablative picosecond Nd:YAG laser was effective for the treatment of the hyperpigmented component of scars.

To investigate the changes of vaginal health and vulvovaginal atrophy (VVA) symptoms following CO2 laser treatment in postpartum breastfeeding women. The number of treatment sessions required to alleviate related symptoms was also determined. Postpartum healthy women who continued breastfeeding and suffered from VVA related symptoms were included in this prospective study. All the participants underwent three consecutive fractional CO2 laser treatments using Lumenis AcuPulse system with FemTouch™ handpiece at four-weeks interval. Following each laser treatment, the severity of VVA symptoms and Vaginal Health Index (VHI) score were assessed as subjective and objective outcomes. The changes in VHI score and VVA symptom severity were compared with baseline data to detect the onset of significant improvement. Thirty postpartum breastfeeding women with VVA symptoms completed the treatment courses and associated measurements. Their age ranged from 25 to 41 with an average of 34.6 years. The mean duration of breastfeeding prior to the initial laser treatment was 3.3 months. Vaginal dryness and dyspareunia were the most bothersome VVA symptoms prior to laser treatment and alleviated after two to three treatment sessions. The significant change of VHI score reaching non-atrophic level was found after the first treatment (media of score post:18 vs. pre:14, p < 0.05) and sustained stable through the following two treatments. Application of fractional CO2 vaginal laser on the management of postpartum vulvovaginal atrophy was proven effectively in our study. Objective and subjective improvements were detected after the first and second laser treatment, respectively. Two consecutive laser treatment sessions were clinically sufficient to alleviate VVA related symptoms in these young female population under postpartum breastfeeding. Objectives: A sufficient histological evaluation is a key pillar in oncological treatment, especially in situations of cancer of unknown primary. CO2 laser technology is used in clinical routine of soft tissue surgery because of its cutting quality and availability. Diode pumped solid state Er(bium):YAG laser systems promise a higher cutting efficiency and minor thermal damages. The aim of this study was to compare both laser systems with respect to their suitability for cutting soft tissue. Methods: A setup was realized which enables comparable experiments with the clinical CO2 laser (AcuPulse 40ST DUO, Lumenis) and the Er:YAG laser system (DPM 40, Pantec Biosolutions AG). Fresh mucosal samples of porcine tongues were used to determine the influence of laser power and sample velocity on cutting depth and thermal damage width for both lasers. In addition, for the Er:YAG laser, the influence of the pulse repetition rate was examined additionally. For analysis, images of histological sections were taken. Results: In all experiments, the Er:YAG laser shows a significantly higher cutting depth (P < 0.0001) and less thermal damage width (P < 0.0001) than the CO2 laser. For example, at an average power of 7.7 W and a sample velocity of 5 mm/s the Er:YAG laser shows a mean cutting depth of 1.1 mm compared to the CO2 laser with 500 μm. While the Er:YAG laser shows a mean thermal damage width of 70 μm compared to 120 μm. Furthermore, the Er:YAG enables the adjustment of the cutting depth and thermal damage width by varying the irradiation parameters. A decrease of the repetition rate leads to a reduction of thermal damage. For example, a repetition rate of 100 Hz results in a thermal damage width of 46 μm compared to 87 μm at 800 Hz at an average power of 7.7 W and a cutting velocity = 5 mm/s while a homogenous cutting quality can be achieved. Conclusions: In conclusion, the results of these ex vivo experiments demonstrate significant advantages of the diode pumped Er:YAG laser system for soft tissue ablation compared to the CO2 laser, in particular regarding cutting efficiency and thermal damage width. Mechanical debulking of laryngeal papillomas is associated with voice disorders due to impairment of the vocal fold's mucosa. Intraepithelial injection of cidofovir reduces damage to the laryngeal structures and thus improves vocal parameters. The aim of our study was to compare vocal quality before and after cidofovir and CO2 laser treatment by means of objective phoniatric parameters and to obtain evidence concerning voice outcomes. The vocal parameters of 42 patients with RRP were assessed before and after intralesional cidofovir and CO2 laser debulking treatment (Lumenis AcuPulse 40 CO2 laser, wavelength 10.6 μm; Lumenis Ltd., Yokneam, Israel). The laser was used in SuperPulse™ mode with power tailored on the target structures (average 7 W). The depth of tissue penetration was 1 mm with a single burst of energy lasting 0.3 ms. Most of the patients had previously undergone traditional surgery (1-105 procedures); in 7/42, the video stroboscopic examination revealed extensive scar tissue covering the mucosa of the vocal folds, limiting the mucosal wave. The significance level for all calculations was p < 0.05. Statistical analysis was performed using Statistica 10 by StatSoft Polska. The methodology included subjective voice evaluation (GRBAS), videostroboscopy, analysis of the acoustic laryngeal tone (MDVP), spectrographic analysis, and voice handicap index (VHI). The GRBAS scale during spontaneous conversation revealed better phonation results after cidofovir treatment in all 42 patients. Scars were not observed in the presented group. In the MDVP laryngeal tone analysis before surgery parameters defining the amplitude and frequency of laryngeal tone were significantly elevated compared to the state after surgery. After treatment, both jitter and shimmer were reduced in all subjects. Even more pronounced changes were observed in the spectrographic analysis. In all analyzed patients, there was a significant reduction in VHI scores showing improvement in voice self-assessment. A satisfactory improvement in voice quality was observed in all RRP patients treated with cidofovir and CO2 laser. The advent of flexible CO2 laser fiber to gynecology arena might represent a turning point in the use of laser energy on a large-scale basis in gynecological surgery. However, there might be some concerns regarding the degree of surgical skills required to use the flexible system. The purpose of our study is to evaluate whether flexible CO2 laser fiber is technically accessible. Fourteen residents in Obstetrics and Gynecology without surgical experience attending laparoscopic box training with both flexible CO2 laser fiber and traditional line-of-sight CO2 laser using Lumenis AcuPulse Duo CO2 laser (Lumenis, Yokne'am Illit, Israel) were prospectively enrolled. Participants were tested at sequential time points on specific surgical tasks and results obtained with the flexible CO2 laser fiber and the traditional line-of-sight CO2 laser were compared. Results were compared by means of paired t-test and a two-tailed P value <0.05 was considered significant. Mean grading at the beginning of training were similar between flexible fiber and line-of-sight CO2 laser. At the end of training, significant improvement in surgical skills was obtained for both techniques, with a statistically significant higher grading for flexible fiber CO2 laser compared to line-of-sight CO2 laser. Our study found that residents without surgical experience show better skills with the flexible CO2 laser fiber delivery system compared to the standard line-of-sight CO2 laser system after a two-month training period with gynecological laparoscopic box. According to our results, flexible CO2 laser fiber delivery system is technically accessible and holds a potential in gynecological surgery. We present the first series of patients treated by transoral laser surgery (TLS) using the new AcuPulse 40

The objectives of this study were to evaluate the safety, tolerability, and efficacy of oxymetazoline hydrochloride cream, 1% (oxymetazoline) when used as an adjunctive treatment with energy-based therapy for patients with moderate to severe facial erythema associated with rosacea. In this Phase 4, multicenter, interventional, open-label study, eligible patients received one of four energy-based therapies (potassium titanyl phosphate laser, intense pulsed light therapy, pulsed-dye laser Vbeam Perfecta, or pulsed-dye laser Cynergy) on day 1 and day 29 and once-daily application of oxymetazoline on days 3 through 27 and days 31 through 56. Improvement from baseline in Clinician Erythema Assessment (CEA) score, patient satisfaction measures, incidence of treatment-emergent adverse events (TEAEs), and worsening from baseline on dermal tolerability assessments and the Clinician Telangiectasia Assessment (CTA) were assessed. Data were summarized using descriptive statistics. A total of 46 patients (mean age, 51.1 years; 78.3% female) enrolled in this study. Similar numbers of patients received each of the energy-based therapies in addition to oxymetazoline. All patients demonstrated an improvement from baseline in CEA during the study with 39 of 43 evaluable patients (90.7%) demonstrating an improvement 6 hours posttreatment on day 56. Most patients were satisfied or very satisfied with treatment at the end of the study. All TEAEs were mild or moderate in severity. Some patients experienced worsening in dermal tolerability assessment symptoms (range: 4-21 patients; 8.7-45.7%). Worsening in CEA and CTA were each reported by three patients (6.5%) at any time during the study. Treatment with oxymetazoline as adjunctive therapy with energy-based therapy was safe, well tolerated, and reduced facial erythema in patients with moderate to severe persistent facial erythema associated with rosacea.

Breast thread lifting is a minimally invasive technique for correcting mild to moderate ptosis, offering aesthetic enhancement with reduced morbidity compared to traditional mastopexy. This review examines the anatomical underpinnings, clinical indications, technical nuances and limitations of breast thread lifting. The breast's fascial architecture, particularly the role of Cooper's ligaments and the retromammary space, critically influences thread trajectory and vector planning. Classification systems assist in proper patient selection, highlighting the suitability of thread lifts for Grades I-II ptosis with minimal skin excess. Advances in ultrasonography have improved preoperative planning, thread placement accuracy and postoperative monitoring. Various thread types, including PDO, PLLA, PCL and Silhouette Soft, offer different lifting capacities and collagen-stimulatory properties, necessitating tailored material selection. Although thread lifts offer immediate improvements, their transient nature necessitates careful patient counseling to manage expectations regarding durability and potential maintenance sessions. Innovative techniques, including clavicular anchoring and multi-level subdermal scaffolding, have expanded the procedural repertoire. Despite certain limitations, breast thread lifting remains a valuable tool within the aesthetic surgeon's armamentarium, particularly for patients seeking minimally invasive options with shortened recovery periods and favorable psychosocial outcomes. Future developments are expected to further enhance safety, reproducibility and long-term results. A clinical study was conducted to determine the effect of nasal valve lift treatment using absorbable, polylactic acid, self-retaining cone threads (Silhouette Soft) in patients with nasal valve stenosis. Sixty patients (n = 60) were included in this prospective study which was performed from January 2015 until December 2018, 19 patients dropped out due to noncompliance. Initially, participants were divided into two equal groups. One was treated by nasal valve lift only, the other additionally received turbinoplasty. A visual analog scale (VAS) was used to rate the sense of nasal ventilation. Patients' satisfaction was examined by a categorical scale, preoperatively, after 1 week, and after 1, 6, 12, 18, and 24 months. For statistical analysis, an univariant variance analysis was conducted to test the significance of differences in nasal breathing within one group at different points of postoperative controls, with the statistical significance set at p < 0.05. Moreover, the two groups were compared with each other regarding results of the categorical scale. After surgical treatment, an improvement is reported by all participants. Average VAS scores were significantly lower between preoperative and every postoperative rating. Although a decline in the effect of breathing improvement is recognizable as threads are dissolved, patients' satisfaction in improvement of nasal breathing is persistent in most cases, even at long-term observation. Overall, these results demonstrate that valve lift is an effective method to treat patients with nasal valve stenosis. Increased demand for rejuvenation of the aging face has led to the evolution of various plastic surgery techniques. This study was conducted to evaluate the surgical efficacy and outcomes of the absorbable suture suspension system related to eyebrow, midface, mandibular, and neck lifting. In this prospective review chart clinical study, a total of 193 patients were included in the study from January 2016 to May 2017. All participants underwent thread lifting using the Proma Happy Lift double needle and Silhouette Soft threads. The patients were followed up for first week and first, third, and sixth month after lifting surgery. Outcomes were assessed by two surgeons and patients based on the GAIS score. A total of 193 patients (mean age: 52.22 ± 11.74 year, range: 25-89), 23 (11.9%) men and 170 (88.1%) women, were included in the study. The most common sites for the face lifting surgery were the jawline (46.1%), midface (33.7%), eyebrows (12.4%), and neck (7.8%). The level of satisfaction increased from 94% in the first week after surgery to 99% in the sixth month after surgery for patients, increased from 94% to 99% for surgeon 1, and increased from 83% to 98% for surgeon 2. The results showed that the level of satisfaction of patients and surgeons increased over time. These results demonstrated that facial rejuvenation thread lift with Proma Happy Lift double needle and Silhouette Soft threads is a being cosmetically more acceptance, safe, and effective procedure associated with minor complications.
