Abstract Background: The purpose of this study is to report the outcomes of mimical reconstruction and aesthetic repair of the nail.Methods: When the width of the pigmented bands was more than 1/2 of the whole nail width, the mimical reconstruction of the nail, the lateral toe pulp island flap covered the wound via the subcutaneous channel, was performed. If the width of the pigmented bands ranged from 1/4 to 2/5 of the entire nail, the aesthetic repair of the nail, the split-thickness excision under microscope, would be carried out.Results: The average age at the time of surgery was 14.5 years. The lesions were located at the toes in 5 patients and fingers in 3 patients. No complications occurred postoperatively. In 5 patients with the mimical reconstruction of the nail, all of toenail showed well-settled flap. In three patients with the aesthetic repair of the nail, there was no nail malnutrition or deformity, and all nails have an aesthetic appearance.Conclusions: Mimical reconstruction and aesthetic repair of the nail following resection of subungual melanocytic nevus is reliable and feasible. It seems to be satisfactory that “like tissue” repairs the complex nail defects. All patients obtain an excellent aesthetic outcome.Level of Evidence: V

Abstract Background: Previous studies have shown about 25% - 33% of cutaneous melanomas result from melanocytic nevi. Currently, there are no consensus on treatment of the subungual melanocytic nevi with the pigmented band width > 3mm. However, some options change post-operative nail appearance and cannot obtain a well aesthetic outcome. The purpose of this study is to report the outcomes of mimical reconstruction and aesthetic repair of the nail.Methods: When the width of the pigmented bands was more than 1/2 of the whole nail width, the mimical reconstruction of the nail, the lateral toe pulp island flap covered the wound via the subcutaneous channel, was performed.

Abstract Background This study aimed to report the outcomes of mimical reconstruction and aesthetic repair of the nail. Methods When the pigmented bands were more than 1/2 the width of the whole nail, mimical reconstruction of the nail was performed, with a lateral toe pulp island flap covering the wound via the subcutaneous channel. If the pigmented bands were 1/4 to 2/5 the width of the entire nail, aesthetic repair of the nail was carried out by split-thickness excision under a microscope. Results The average age of patients at the time of surgery was 14.5 years. Five patients had lesions on their toes, while three had lesions on their fingers. There were no post-operative complications. All toenails of the five patients who had undergone mimical reconstruction exhibited a well-settled flap. The nails of the three patients who underwent aesthetic repair displayed no nail malnutrition or deformity, and all nails had an aesthetic appearance. Conclusions Both mimical reconstruction and aesthetic repair of the nail following resection of subungual melanocytic nevus are reliable and feasible. The “like tissue” repairs of complex nail defects appear to be satisfactory. All patients had excellent aesthetic outcomes. Level of evidence V

Subfascial Breast Augmentation

Abstract Background Subfascial breast augmentation is a technique originally developed to reduce the risks of capsular contracture while decreasing the postoperative pain associated with subpectoral augmentation. It was pioneered in Brazil by Dr. Graf and others, and recently this technique has gained interest in the aesthetic world. Objectives The goal of this study was to provide a systematic analysis of subfascial breast augmentation to assess the combined reported rates of capsular contracture, animation deformity and complications. Methods The PubMed, Embase, and Web of Science databases were searched for the use of the subfascial plane for breast augmentation. We included studies that reported on capsular contracture and other outcomes following subfascial breast augmentation. Results Through the initial search, 26 articles were identified. Of which, 22 were included in the final study. A total of 3743 patients were identified across these studies with a total number of 38 cases of capsular contracture representing a rate of 1.01% of capsular contracture. Several articles reported on demographics, perioperative and long-term complications, and outcomes with regards to the aesthetic outcome from the surgeon’s perspective. Several infections were reported representing a rate of 0.1%. Animation deformity was not reported, although rippling was occasionally reported as was malrotation, axillary banding, sensory deficit, and asymmetry. Subfascial breast augmentation appears to have a low complication rate and an extremely low rate of capsular contracture at approximately 1%. Conclusions Subfascial breast augmentation may provide the benefits of low rates of capsular contracture while avoiding the discomfort and future animation deformity of subpectoral augmentation.

Abstract Background Immediate loading is an attractive option for avoiding secondary surgery. However, it is unclear whether it provides a better aesthetic outcome compared to conventional loading with implants placed in healed ridges. Aims To compare the aesthetic outcomes of immediately and conventionally loaded single implants in healed anterior maxillary ridges. Methodology A systematic review using PICO was conducted. EMBASE, MEDLINE and DoSS databases were searched. The Cochrane Risk of Bias tool for Randomised Controlled Trials and the Effective Public Health Practice Project tool for other study designs were used for quality appraisal. A narrative synthesis was undertaken. Results A total of 622 articles were identified. After screening, a total of five papers were included. Results indicated no statistically significant difference in pink or white aesthetic scores between the immediate and conventional loading groups at 1- and 5-year review and the Papilla Index at the 1-year review. Conclusion Within the limitations of this review, immediate loading of single implants provides a comparable aesthetic outcome to conventional loading in healed ridges of the anterior maxillary.

Abstract Background An increasing number of women wish breast implant removal whilst maintaining an acceptable projection and form were possible. Objectives The authors propose a technique to remodel the breast after implant removal utilizing internal suture loops to project the breast, recruit abdominal and axillary tissue cranially and medially, and provide a matrix for lipofilling. Methods A prospective analysis was performed of consecutive patients undergoing implant extraction followed by power-assisted liposuction loops and lipofilling. Patient characteristics were measured. The aesthetic results were evaluated by 2 independent raters. Patient-reported satisfaction was measured by standardized questionnaires. Results Implants in 52 patients with an average age of 55 and body mass index of 23.7 were extracted followed by breast remodeling. A total of 73% of patients had implants for aesthetic reasons, 41% were smokers, and 43% of the reconstruction cases received radiotherapy. A total of 28% had implant extraction for rupture, 58% for capsular contracture, and 14% due to pain and migration. The average volume of the implants removed was 292 cc, followed by an average lipofilling of 223 cc, yielding a ratio of 0.76 to 1. The average tissue recruited by loops was 82.5 cc. Independent raters measured 79% of results as good, 13% as acceptable, and 8% as requiring improvement; 80% of patients were satisfied to very satisfied. Conclusions The authors propose implant extraction followed by power-assisted liposuction loops and lipofilling can provide footprint definition, sustained projection, and high patient satisfaction. Moreover, the recruitment of a vascularized adipo-cutaneous flap by loops allows a reduced ratio of fat grafting to implant volume. Level of Evidence: 4

Since the early days of gene therapy, both the scientific community and the public have perceived the ethical challenges intrinsic to this discipline. First, the technology exploited by gene therapy is still experimental and burdened by important safety issues. Second, in several instances gene therapy aims at stably modifying the genetic characteristics of individuals. Third, the same modifications could in principle be applied also to embryos, foetuses or germ cells. Finally, while gene therapy applications are generally accepted for therapeutic purposes, the same gene transfer technologies could also be exploited to improve the aesthetic appearance, or the physical and intellectual performance of people. The definition of suitable guidelines for a controlled, ethically accepted translation of gene therapy to the clinics remains a major challenge for the near future.

Background: Treatment of preaxial foot polydactyly, a duplication of the first ray, consists of excision of an extra ray, aiming to improve shoe fitting and aesthetic appearance, while maintaining foot function. Currently, the effect of excision on foot function and foot-related patient experiences is unclear. Methods: A cross-sectional comparison between 37 children treated for preaxial foot polydactyly and 37 age- and sex-matched healthy controls was performed. Dynamic foot function was assessed using plantar pressure measurements and static foot characteristics by physical examination. Patient-reported outcomes for foot function and footwear were evaluated, using the Oxford Ankle Foot Questionnaire for Children (score, 0-100). Results: Compared with controls, patients had significantly lower median peak pressures at the hallux (148 kPa [IQR, 98-245] vs 272 kPa [IQR, 205-381], P < .001) and significantly higher peak pressures at the second metatarsal (217 kPa [IQR, 147-338] vs 166 kPa [IQR, 141-235], P = .002) and third to fifth metatarsals (214 kPa [IQR, 147-290] vs 161 kPa [IQR, 135-235], P < .001). Additionally, patients had a more medially deviated hallux, both while seated (15 degrees (IQR, 11-20) vs 12 degrees [IQR, 10-15], P = .001) and standing (20 degrees [IQR, 15-26] vs 18 degrees [IQR, 15-20], P = .001). No significant correlation between peak pressure distribution and hallux deviation was found. Patients reported minimal problems with foot function (87.5 [IQR, 64.6-100]), but distinct problems with footwear use (50.0 [IQR, 25.0-100]). Conclusion: Patients with surgically treated preaxial foot polydactyly had a substantially altered plantar pressure distribution with more lateral foot progression than healthy controls. Although an increased hallux deviation was not related to altered foot function, it seemed to be the reason for the patient-perceived problems with footwear. Level of Evidence: Level III, comparative series.

The natural beauty of coral reefs attracts millions of tourists worldwide resulting in substantial revenues for the adjoining economies. Although their visual appearance is a pivotal factor attracting humans to coral reefs current monitoring protocols exclusively target biogeochemical parameters, neglecting changes in their aesthetic appearance. Here we introduce a standardized computational approach to assess coral reef environments based on 109 visual features designed to evaluate the aesthetic appearance of art. The main feature groups include color intensity and diversity of the image, relative size, color, and distribution of discernable objects within the image, and texture. Specific coral reef aesthetic values combining all 109 features were calibrated against an established biogeochemical assessment (NCEAS) using machine learning algorithms. These values were generated for ∼2,100 random photographic images collected from 9 coral reef locations exposed to varying levels of anthropogenic influence across 2 ocean systems. Aesthetic values proved accurate predictors of the NCEAS scores (root mean square error < 5 forN≥ 3) and significantly correlated to microbial abundance at each site. This shows that mathematical approaches designed to assess the aesthetic appearance of photographic images can be used as an inexpensive monitoring tool for coral reef ecosystems. It further suggests that human perception of aesthetics is not purely subjective but influenced by inherent reactions towards measurable visual cues. By quantifying aesthetic features of coral reef systems this method provides a cost efficient monitoring tool that targets one of the most important socioeconomic values of coral reefs directly tied to revenue for its local population.

Microtia is a congenital malformation affecting one in 5000 individuals and is characterized by physical deformity or absence of the outer ear. Nowadays, surgical reconstruction with autologous tissue is the most common clinical practice. The procedure requires a high level of manual and artistic techniques of a surgeon in carving and sculpting of harvested costal cartilage of the patient to recreate an auricular framework to insert within a skin pocket obtained at the malformed ear region. The aesthetic outcomes of the surgery are highly dependent on the experience of the surgeon performing the surgery. For this reason, surgeons need simulators to acquire adequate technical skills out of the surgery room without compromising the aesthetic appearance of the patient. The current paper aims to describe and analyze the different materials and methods adopted during the history of autologous ear reconstruction (AER) simulation to train surgeons by practice on geometrically and mechanically accurate physical replicas. Recent advances in 3D modelling software and manufacturing technologies to increase the effectiveness of AER simulators are particularly described to provide more recent outcomes.
