Background Processed lipoaspirate grafting describes several techniques theorized to leverage the inflammatory and regenerative capacities of mechanically processed adipocytes to rejuvenate and correct skin pathology. While lipoaspirate grafting is typically leveraged to fill visible defects such as depressed scars and dermal lines, additional fat processing allows grafts to stimulate mechanisms of wound healing, including the promotion of fibroblast activation, neovascularization, and neocollagenesis. Objectives This study intends to assess the efficacy and tolerability of processed lipoaspirate grafting monotherapy to improve the clinical appearance of atrophic acne scars. Methods Subjects underwent a single autologous processed lipoaspirate grafting procedure at the site of atrophic acne scars. Objective and subjective scar analysis was performed at 3- and 6-months post-treatment. Scars were assessed via standard photography, topographic analysis, and noninvasive skin measurements. In addition, microbiopsies were obtained before and after treatment to assess histological or genetic changes. Clinical improvement was assessed using Subject and Clinician Global Aesthetic Improvement Scales (GAIS) and blinded photographic evaluation. Results Ten subjects between ages 18 and 60 completed the study. Clinical evaluation demonstrated that fat grafting improved the appearance of atrophic acne scars. CGAIS and SGAIS score showed clinical improvement at both 3- and 6-month follow-up compared to baseline (p Conclusions Micronized lipoaspirate injection is a viable and effective option to improve the appearance of facial acne scarring. Favorable improvements in atrophic acne scarring were captured by objective analysis of skin ultrastructure as well as improvement in subjective assessments of scarring.

Intense pulsed light (IPL) is a noninvasive therapeutic option to treat benign pigmented lesions by targeting melanin.The purpose of this study was to assess IPL as a treatment for benign pigmented dorsal hand lesions.A total of fifteen subjects, 40 to 73 years old, received 3 monthly IPL treatments over the dorsal hands. Subjects followed up 1 and 3 months after treatment. At every visit, photographs were taken using the VISIA Complexion Analysis System (Canfield Scientific, Fairfield, NJ) and analyzed using the RBX Brown Spots Analysis algorithm. The Clinician Global Aesthetic Improvement Scale and Subject Global Aesthetic Improvement Scale were completed at both follow-up visits.A total of fifteen subjects completed all six visits. The number of brown spots decreased 9.26% ( p = .0004) and 7.52% ( p = .0132) at each follow-up visit. The mean brown intensity decreased 6.15% ( p = .0183) and 7.67% ( p = .0178), whereas the mean contrast intensity decreased 8.88% ( p.0001) and 6.60% ( p = .0007) 1 and 3 months after treatment, respectively. The mean Clinician Global Aesthetic Improvement Scale was 2.03 and 2.23, whereas the mean Subject Global Aesthetic Improvement Scale 1 and 3 months after treatment was 1.6 and 1.8, respectively.Objective analysis, along with clinician and subject assessments, showed an improvement in the appearance of benign pigmented lesions in the treated area after 3 IPL treatments.

Background Noninvasive treatments for skin tightening are gaining popularity. However, no studies have assessed bipolar fractional radiofrequency treatment on suprapatellar skin. Objectives The purpose of this study was to evaluate the efficacy of bipolar fractional radiofrequency treatment on suprapatellar skin. Methods Twenty patients received 1 bilateral suprapatellar bipolar fractional radiofrequency treatment. They returned 7 days, 3 weeks, 3 months, and 6 months posttreatment. Noninvasive measurements were obtained at each visit, including high-resolution ultrasonography, optical coherence tomography, transepidermal water loss and skin elasticity. Microbiopsies were collected in the treatment area for histologic and gene expression analyses. Three clinicians completed photographic evaluations comparing texture and laxity at baseline vs 6 months posttreatment. Results Fifteen subjects completed all 6 visits. Both transepidermal water loss and dermal-epidermal junction roughness were increased at 3 weeks and 3 months posttreatment. Both attenuation coefficient and stiffness were increased significantly at 3 and 6 months posttreatment. Blood flow 0.5 mm below the surface and expression of epidermal hyaluronic acid and inflammatory genes IL-1b and IL-6 were significantly higher at 7 days posttreatment compared with pretreatment and 3 months posttreatment. There were no statistically significant changes in collagen- or elastin-related genes and proteins at 7 days or 3 months posttreatment. An improvement in texture and laxity was observed at 6 months posttreatment in 17.7% and 24.4% of photographs, respectively. Conclusions Radiofrequency treatment by microneedling of suprapatellar skin shows limited effects in decreasing skin laxity and improving skin appearance. At a molecular level, the treatment resulted in lower elastin and hyaluronic acid levels and increased dermal-epidermal junction roughness based on histology and optical coherence tomography imaging.

Background Although ablative techniques are the standard of care for the treatment of fine lines and wrinkles, microneedling offers a minimally invasive alternative. Objectives The purpose of this study was to assess the efficacy of microneedling on facial and neck fine lines and wrinkles. Methods Thirty-five subjects between 44 and 65 years old with Fitzpatrick skin types I to IV received 4 monthly microneedling treatments over the face and neck. Subjects returned 1 and 3 months posttreatment. At every visit, high-resolution ultrasonography and optical coherence tomography were performed, and transepidermal water loss and skin elasticity were measured. Microbiopsies (0.33 mm) were collected pretreatment, before the fourth treatment and 3 months posttreatment. Results Thirty-two subjects (30 females, 2 males) completed all 7 visits. Facial dermal and epidermal density increased 101.86% and 19.28%, respectively, from baseline at 3 months posttreatment. Facial elasticity increased 28.2% from baseline at 3 months posttreatment. Facial attenuation coefficient increased 15.65% and 17.33% at 1 and 3 months posttreatment, respectively. At study completion, blood flow at a depth of 300 µm decreased 25.8% in the face and 42.3% in the neck. Relative collagen type III and elastin gene expression was statistically higher 3 months posttreatment. However, total elastin protein levels were unchanged from baseline values. Dermal muscle formation was observed in 58% of biopsies extracted 3 months posttreatment compared with 15.3% at baseline. Conclusions The results illustrate the effects of microneedling treatments. Noninvasive measurements and biopsy data showed changes in skin architecture and collagen/elastin gene expression, suggesting skin rejuvenation, with new extracellular matrix production and muscle formation.

Recent advancements in laser technology have led to its expanded utilization in smaller clinical settings and medical spas, particularly for facial rejuvenation and the treatment of other aesthetic concerns. Despite the increasing popularity of this technology, discussion of laser safety programs has remained limited, mostly to operating rooms at larger clinical institutions. Although smaller facilities do not operate at the same capacity as a large hospital or medical center, the requirements for utilizing a laser are no less stringent. Employers must comply with local and federal regulations, the Occupational Safety and Health Administration (OSHA) General Duty Clause, American National Standards Institute (ANSI) standards, and professional recommended practices applicable to their business. Although the laser safety officer (LSO) is often a full-time position within larger facilities, smaller clinical settings and medical spas may be limited in staff number. It is important, therefore, that clinical practices establish laser policies and procedures with consideration of their individual needs and capabilities. In this paper, we will define a laser safety program, highlight basic requirements needed to establish this program, and outline the specific responsibilities of the LSO. To ensure that safe laser practices are being conducted at the healthcare facility, it is imperative that small business owners are aware of these regulations and standards in place for the operation of laser systems.

Background Despite the proven efficacy of liposuction, there is a population of patients who prefer non-surgical alternatives. Laser hyperthermia-induced lipolysis has emerged as one non-invasive alternative to liposuction. Objectives The authors sought to evaluate the safety and efficacy of a 1060-nm (±10 nm) diode laser for non-invasive fat reduction of the abdomen. Methods This single-arm, 2-center study enrolled 30 patients. Patients received a 25-minute 1060-nm diode laser treatment on their abdomen. Ultrasound adipose measurements, body weight, and circumference were taken at baseline and at 6- and 12-week follow-up visits. Blinded evaluators identified “before” and “after” photos of each patient. A patient satisfaction questionnaire was completed by each patient at study exit. Results A total 29 patients completed all treatment and follow-up visits. Ultrasound images showed an adipose reduction of 8.55% at 12 weeks post-treatment (P Conclusions These results indicate that a single treatment with a 1060-nm (±10 nm) diode laser, per the treatment protocol, is safe and effective in reducing unwanted fat in the abdomen as objectively measured employing ultrasound. The treatment was well-tolerated among all patients, with minimal discomfort reported and high patient satisfaction. Level of Evidence: 4

Background Advances in gluteal fat grafting have resulted in diminished risks through improved understanding of regional anatomy and technical nuances. No anatomic studies identifying the presence or absence of buttock fat compartments have yet been reported. Objectives The aim of this cadaveric study was to identify and characterize the deep subcutaneous gluteal fat compartments to further understand the nuanced differences between deep and superficial subcutaneous fat layers. Methods A cadaveric study was performed to identify the fat compartments. Latex injection into the iliac artery and vein was used to prepare 4 fresh (N = 8 hemibuttocks) hydrated cadavers for dissection. Preliminary work identified the likely position of deep gluteal fat compartments. The cannula was positioned under ultrasound guidance in between the superficial and deep gluteal layers. Cadaveric buttocks were infiltrated by the static technique with dyed human fat, dyed applesauce, and dyed saline in an attempt to identify the gluteal deep subcutaneous fat compartments. Results Dissection identified and characterized 7 discrete deep gluteal fat compartments. These comprise 3 medial fat compartments (superior, middle, and inferior); a central fat compartment; and 3 lateral (superior, middle, and inferior) deep fat compartments. Conclusions Seven deep gluteal fat compartments have been identified that have distinct boundaries and maintain injected contents separate from each other above the gluteal muscle fascia. These compartments can be selectively expanded for buttock augmentation. Knowledge of these compartments enables surgeons to perform gluteal augmentation by static infiltration, injecting autologous fat under ultrasound guidance in the deep subcutaneous fat layer, while optimizing aesthetic considerations. Resumen Antecedentes Los avances en el injerto de grasa glútea han dado como resultado una disminución de los riesgos a través de una mejor comprensión de la anatomía regional y los matices técnicos. Aún no se ha informado de estudios anatómicos que identifiquen la presencia o ausencia de compartimentos grasos en los glúteos. Objetivos El objetivo de este estudio cadavérico fue identificar y caracterizar los compartimentos profundos de grasa glútea subcutánea a fin de comprender mejor las diferencias detalladas entre las capas de grasa subcutánea profunda y superficial. Métodos Se realizó un estudio cadavérico para identificar los compartimentos de grasa. Se empleó una inyección de látex en la arteria y vena ilíacas para preparar 4 cadáveres hidratados frescos (N=8 hemiglúteos) para su disección. El trabajo preliminar identificó la probable posición de los compartimentos profundos de grasa glútea. Se posicionó la cánula bajo guía de ultrasonido entre las capas glúteas superficial y profunda. Los glúteos cadavéricos se infiltraron con grasa humana teñida, puré de manzana teñido y solución salina teñida usando la técnica estática en un intento por identificar los compartimentos de grasa subcutánea profunda en los glúteos. Resultados La disección identificó y caracterizó 7 compartimentos discretos de grasa glútea profunda. Éstos comprenden 3 compartimentos de grasa medial (superior, medio e inferior), un compartimento de grasa central y 3 compartimentos laterales (superior, medio e inferior) de grasa profunda. Conclusiones Se han identificado siete compartimentos profundos de grasa glútea que tienen límites distintos y mantienen los contenidos inyectados separados entre sí por encima de la fascia del músculo glúteo. Estos compartimentos se pueden expandir selectivamente para el aumento de glúteos. El conocimiento de estos compartimentos permite a los cirujanos realizar el aumento de glúteos mediante infiltración estática, inyectando grasa autóloga bajo guía de ultrasonido en la capa de grasa subcutánea profunda, al tiempo que se optimizan las consideraciones estéticas.

Background Skin scarring can occur after punch biopsies, prohibiting their routine utilization, especially in the central face. Objectives This paper describes a scarless, 0.33-mm-diameter skin microbiopsy for molecular analysis of skin. Methods This is was single-center, randomized, prospective study with 15 patients receiving no biopsy or biopsy on the left or right nasolabial fold. Six blinded raters assessed participant photos at baseline, 1 month, and 3 months post biopsy to evaluate for a visualized scar. Patient and Observer Scar Assessment Scale was completed. Additionally, biopsies from various skin regions of body along with arm skin after treatment with a single Erbium-YAG laser were processed for molecular analysis. Results No patients exhibited scar formation based on evaluation of photographs and patient feedback. There was no mark at the biopsy site 7 days post-procedure. Optical coherence tomography showed a complete closing of the biopsy-punch wound 48 hours post-biopsy. One month post-biopsy, photography reviewers were unable to identify a scar, on average, 90% of the time at 3-month follow-up. Microbiopsies from various anatomical regions were successfully extracted for histology, electron microscopy, and gene expression analysis. Selected skin rejuvenation markers in the biopsies from Erbium-YAG–treated forearm skin resulted in significant gene upregulation in extracellular matrix molecules at 1 month posttreatment compared with untreated skin. Conclusions A core microbiopsy of 0.33 mm can be extracted reproducibly for histological, ultrastructural, and gene expression analysis without scarring. This allows repeated sampling for assessment of skin treatments and diseases, including aesthetics and wound-healing progress.

Background It is dangerous, although not uncommon, in some clinical settings for laser operators to place gauze underneath external patient protective eyewear when performing laser procedures. Objectives The purpose of this study was to evaluate 4 lasers, commonly used for aesthetic facial procedures, on 3 materials commonly found in the clinical setting. Methods We performed tests with 4 lasers: the 2940-nm erbium-doped yttrium aluminum garnet (Er:YAG) laser, the 532-nm potassium titanyl phosphate (KTP) laser, the 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser, and a Lumenis UltraPulse 10,600-nm carbon dioxide (CO2) laser. Their effects were evaluated on dry gauze pads, wet gauze pads, and adhesive external eye shields. Results When exposed to the 2940-nm Er:YAG and 10,600-nm CO2 lasers, dry gauze smoked on the first pulse and ignited on the second pulse, whereas no damage occurred to the wet gauze or adhesive eye shields after 8 and 4 pulses, respectively. No damage to any material or the underlying surface was seen after 30 pulses of the 532-nm KTP laser. After 2 pulses of the 1064-nm Nd:YAG laser, the adhesive eye shields sparked; dry gauze smoked after 1 pulse, but no damage to the underlying surface occurred after 30 pulses. Conclusions The results of our study highlight the inherent flammability of gauze when exposed to lasers commonly used to address aesthetic facial concerns. Although moistened gauze conveyed more protection than dry gauze, these results do not guarantee patient ocular safety. Therefore, we do not recommend the use of any gauze under protective eyewear.

Background During their work on the cerebrospinal fluid (CSF) circulatory system of human nerves and brain, the authors applied imaging and tissue techniques that complemented basic anatomical dissection. Objectives The authors sought to show how integrating fluorescent imaging and basic immunohistochemistry (IHC) with facial anatomy can address current problems in aesthetic surgery. Methods The authors developed an algorithm and a set of principles from their work on the CSF circulatory system and applied these to 3 problems in aesthetic surgery: the functional anatomy of the vermilion-cutaneous junction; chemosis; and the functional anatomy of periosteal fixation. Results Integrating fluorescent imaging and IHC with anatomical dissection characterizes structural and functional anatomy. Fluorescent imaging helps to identify and locate easily missed structures. IHC defines cell type and function. The vermilion-cutaneous junction is defined by a major lymphatic vessel. Lymphatic flow from the medial limbus to the lateral canthus suggests the etiology of chemosis. Periosteal sites of fixation prevent shear where dural CSF vessels drain directly to subcutaneous lymphatics. Conclusions Integrating anatomical dissection with fluorescent imaging and basic IHC characterizes structural and functional anatomy and helps to better understand many problems encountered in aesthetic surgery.

Background and objective Patient-reported outcomes and blinded observer rating scales are subjective and unreliable but are extensively utilized to evaluate cosmetic office-based treatments, including ablative lasers. This study aims to assess the practicality of using non-invasive and minimally invasive methods for objective skin assessment following a skin rejuvenation treatment. Study design/materials and methods Twelve patients received a single 1,470/2,940 nm laser treatment for facial rejuvenation. Assessments were performed before treatment, and 7 days, 3 weeks, and 3 months post-treatment. Images were taken with the VISIA Skin Analysis System to measure wrinkles, textures, pores, ultraviolet (UV) spots, brown spots, red areas, and porphyrins. Other non-invasive skin measurements-high-resolution ultrasonography, optical coherence tomography, transepidermal water loss and BTC 2000-were used to measure epidermal/dermal thickness, blood flow, surface roughness, wrinkle depth, attenuation coefficient, elasticity, laxity, and viscoelasticity. Microbiopsies (0.33 mm in diameter or the equivalent of a 23-gauge needle) were collected for histology and gene expression of tissue rejuvenation. Results Significant improvement in facial skin aesthetics after laser treatment was recorded in UV spots, brown spots and pores after 3 weeks and in UV spots and brown spots after 3 months. The dermal attenuation coefficient decreased significantly at 3 weeks, while blood flow 0.5 to 0.7 mm below the skin surface increased significantly between 5 days and 3 weeks following treatment. Epidermal hyaluronic acid expression assessed by immunostaining and expression of inflammatory genes were elevated at 7 days post-treatment compared with untreated or 3 months post-treatment. There were no statistically significant changes in collagen or elastin-related genes between groups at the studied parameters. Conclusion Non-invasive devices can be effectively used to provide objective measurements of skin structure, pigmentation, blood flow, and elasticity to assess the efficacy of facial skin rejuvenation treatments. Furthermore, microbiopsies can objectively evaluate facial skin rejuvenation without scarring. Using non-invasive skin imaging, a single treatment with the 1,470/2,940 nm laser was observed to be effective in improving skin appearance after 3 months, namely in reducing UV spots and brown spots, without significant changes in the tissue at the molecular level, as assessed by microbiopsy.

Background Historically, standard evaluations for photoaging have involved subjective analysis; recently, however, investigators have turned to noninvasive systems for more objective evaluation of facial aging. Objectives The aim of this study was to establish a clinical correlation between the Glogau Photoaging Scale and the VISIA-CR Complexion Analysis System (Canfield Imaging Systems, Fairfield, NJ), and thereby reduce intra- and interobserver variability when assessing photodamage. Methods In total, 117 subjects aged between 18 and 89 years were included. Two-dimensional facial photographs were analyzed by 3 independent reviewers and assigned Glogau scores. Images were also captured and analyzed with VISIA software. Data were grouped by median Glogau score and compared between groups. Results All groups were statistically different (P Conclusions The results illustrate that an imaging system can be used to reliably determine objective scores correlating to Glogau photoaging evaluations, and indicate that aging appears to be an exponential process. Collectively, these findings will assist future investigations of facial aging and the therapeutic options available for facial skin rejuvenation, and enable objective assessment of treatment outcomes.

On January 31, 2018, The Multi-Society Task Force for Safety in Gluteal Fat Grafting released a practice advisory regarding gluteal fat grafting. The task force was assembled in the wake of several highly publicized patient deaths involving Brazilian Butt Lift (BBL) and produced a second practice advisory in August 2019. In 2021, The Aesthetic Surgery President commissioned a Working Group on BBL Patient Safety, charging the group to address new guidelines affecting safety and welfare of BBL patients. The “Practice Advisory on Gluteal Fat Grafting” is the first advisory developed since the working group was formed. In addition to surgical technique as a major cause of fatal complications of BBL, the working group focused on micro-economic trends of operative time and regional BBL pricing and considered fatigue and distraction in formulating the current guidelines. In Florida, the majority of BBL deaths occur at the end of the week. Such a non-normalized distribution most likely represents the result of fatigue and/or distraction, which has been linked to surgical mortality in multiple published communications. In addition, mortality is likely due to uncertainty or lack of documentation as to the correct plane of fat injection. Therefore, the newest and most compelling recommendations from these guidelines include the utilization of ultrasound-guided documentation of cannula placement prior to and during fat injection, and the limitation of 3 BBL cases as a maximum amount of total operative cases per day. The authors thank members of the task force for the insights they brought to this process. Level of Evidence: 4

Background A microneedling pen has been cleared by the US FDA and is indicated for improving the appearance of facial acne scars in adults. Objectives The aim of this study was to assess the effectiveness of this microneedling pen for treating wrinkles. This paper focuses on the results on the neck, an area of recent importance with video meetings placing physical stress on the neck area, leading to wrinkles. Methods Healthy adult men and women were enrolled (N = 35). Subjects received 4 monthly microneedling procedures at depths of up to 2.5 mm. Wrinkle assessments were performed by 2 trained blinded raters by comparing images of each subject at baseline and at 90 days postprocedure. The 2 raters were unblinded for the Clinician’s Global Aesthetic Improvement Scale assessment. Subjects completed the Subject’s Global Aesthetic Improvement Scale and a questionnaire regarding satisfaction with the treated areas of the face and neck at 30 and 90 days posttreatment. Results The study was completed by 32 subjects. Wrinkle assessments demonstrated significant improvement in the neck areas (P Conclusions Microneedling is a viable, minimally invasive option for treating wrin kles of the neck.

Background The rapidly increasing modalities and mediums of clinical photography, use of 3-dimensional (3D) and 4-dimensional (4D) patient modeling, and widening implementation of cloud-based storage and artificial intelligence (AI) call for an overview of various methods currently in use as well as future considerations in the field. Objectives Through a close look at the methods used in aesthetic surgery photography, clinicians will be able to select the modality best suited to their practice and goals. Methods Review and discussion of current data pertaining to: 2-dimensional (2D) and 3D clinical photography, current photography software, augmented reality reconstruction, AI photography, and cloud-based storage. Results Important considerations for current image capture include a device with a gridded viewing screen and high megapixel resolution, a tripod with leveling base, studio lighting with dual-sourced light, standardized matte finish background, and consistency in patient orientation. Currently, 3D and 4D photography devices offer advantages such as improved communication to the patient on outcome expectation and better quality of patient service and safety. AI may contribute to post-capture processing and 3D printing of postoperative outcomes. Current smartphones distort patient perceptions about their appearance and should be used cautiously in an aesthetic surgery setting. Cloud-based storage provides flexibility, cost, and ease of service while remaining vulnerable to data breaches. Conclusions While there are advancements to be made in the physical equipment and preparation for the photograph, the future of clinical photography will be heavily influenced by innovations in software and 3D and 4D modeling of outcomes.

Assessments of non-surgical office-based aesthetic treatments' efficacy including lasers are mostly based on subjective evaluation of clinical photography. Accumulating evidence suggest that non-invasive skin imaging such as optical coherence tomography (OCT) can be effectively used to assess not only the skin surface but also the underlying epidermis and dermis, providing objective and clinically relevant data. In this review, we highlight the potential of OCT imaging for the aesthetic medicine field along with OCT measurement parameters and their clinical relevance to healthy and pathological skin conditions.

Their group previously demonstrated high-patient satisfaction for the treatment of hypertrophic burn scar (HBS) with the erbium: yttrium aluminum garnet (Er:YAG) laser, but this and other literature supporting the practice suffer from a common weakness of a reliance on subjective assessments by patients or providers. Herein, they sought to prospectively study the effects of Er:YAG fractional ablation on HBS using noninvasive, objective technologies to measure outcomes. Patients with HBS had identical regions of scar designated for treatment by the Er:YAG laser (TREAT) or to be left untreated (CONTROL). They prospectively collected scar measurements of TREAT and CONTROL regions preoperatively, 3 weeks, and 3 months after Er:YAG treatment. Scar measurements included viscoelastometry, transepidermal water loss, optical coherent tomography, and high-frequency ultrasound. Outcomes were measured for the aggregate difference between the TREAT group vs the CONTROL group, as well as within each group in isolation. Seventeen patients were seen preoperatively, followed by n = 15 at 3 weeks and n = 11 at 3 months. A mixed-model repeated measures analysis showed no significant effect of fractional ablation when comparing the overall TREAT group measurements with those of the CONTROL group. However, when considered as within-group measurements, TREAT scars showed significant improvement in viscoelastic deformity (P = .03), elastic deformity (P = .004), skin roughness (P = .05), and wrinkle depth (P = .04) after fractional ablation, whereas CONTROL scars showed no such within-group changes. HBS treated by the Er:YAG laser showed objective improvements, whereas no such changes were seen within the untreated scars over the same time frame.

Background There has been an increase in body contouring procedures following massive weight loss (MWL), including male breast reduction procedures. Treating male chest deformity after MWL using standard mastopexy techniques often leads to suboptimal results. Objectives The authors describe a technique to treat pseudogynecomastia using a modified elliptical excision and nipple-areola complex (NAC) transposition on a thinned inferior dermal pedicle as an alternative to conventional techniques. Methods A retrospective chart review from January 2011 to January 2019 identified a total of 14 male patients who underwent excision of pseudogynecomastia using the described technique. Results Patients were characterized by age, method of weight loss, pre-weight loss body mass index (BMI), post-weight loss BMI, total weight loss, grade of pseudogynecomastia, and concurrent procedures performed. Patients were followed for a period ranging from 3 months to 1.5 years (average, 8.1 months). Pre-weight loss BMI and post-weight loss BMI averaged 52.0 kg/m2 and 29.6 kg/m2, respectively. The average weight lost was 79.72 kg and the average total amount of tissue removed was 2615 g. All patients had concurrent procedures with an average operative time of 274 minutes. Four out of 14 patients (28.6%) experienced minor complications, which included asymmetry, delayed wound healing, seroma, and hyperpigmentation. There were no wound infections, hematomas, flap necrosis, or dysesthesia. Conclusions Due to several cosmetic advantages and low complication profile, our technique using a modified elliptical excision and NAC transfer on an inferior dermal pedicle is an attractive option for treating male chest deformity after MWL.

Background As the number of patients requiring bariatric surgery has increased, so has the demand for body contouring after massive weight loss. Surgery involving the abdomen in these patients is particularly challenging as both vertical and horizontal laxity if often present, making traditional abdominoplasty techniques less effective. Objectives The aim of this study was to review the operative technique and evaluate the preoperative comorbidities and operative decisions that may impact patient outcomes in those undergoing vertical abdominoplasty. Methods A review of the authors’ technique is described. A retrospective chart review of patients who underwent vertical abdominoplasty for significant vertical and horizontal laxity after massive weight loss by a single surgeon between June 2007 and July 2019 was performed. Preoperative parameters, operative factors, and minor and major complications were evaluated. Results Our complication rate was 81% (13/16), which were all minor. No major complications were encountered. Patients with a history of nicotine use had a 100% complication rate. There was a trend toward higher seroma formation in patients with coronary artery disease and those with a history of smoking. There was also a trend toward higher wound dehiscence in patients with renal disease. The authors found no statistically significant correlation between complications and older age, higher weight of tissue resected, higher body mass index, and medical comorbidities. Conclusions This small series helps to elucidate the role of vertical abdominoplasty in the care of patients following massive weight loss and its associated morbidity. Proper patient selection, appropriate preoperative patient counseling, and sound surgical technique help to mitigate the negative outcomes. Level of Evidence: 4

The advent of three-dimensional (3D) printing in the 1980s ushered in a new era of manufacturing. Original 3D printers were large, expensive and difficult to operate, but recent advances in 3D printer technologies have drastically increased the accessibility of these machines such that individual surgical departments can now afford their own 3D printers. As adoption of 3D printing technology has increased within the medical industry so too has the number of 3D printable materials. Selection of the appropriate printer and material for a given application can be a daunting task for any clinician. This review seeks to describe the benefits and drawbacks of different 3D printing technologies and the materials used therein. Commercially available printers using fused deposition modelling or fused filament fabrication technology and relatively inexpensive thermoplastic materials have enabled rapid manufacture of anatomic models and intraoperative tools as well as implant prototyping. Titanium alloys remain the gold-standard material for various implants used in the fixation of craniofacial or extremity fractures, but polymers and ceramics are showing increasing promise for these types of applications. An understanding of these materials and their compatibility with various 3D printers is essential for application of this technology in a healthcare setting.

The advancement of laser technology has seen its use gain popularity across a wide range of specialties to treat diseases, as well as address aesthetic concerns. In order to protect both the patient and the healthcare personnel providing treatment, instruction and knowledge of laser safety remain of utmost importance. In this paper, we discuss the classification of laser systems, review ocular injuries that may be caused by inappropriate laser exposure, and provide background on laser protective eyewear. In addition, we highlight the current recommendations for proper eyewear during laser use outlined in the American National Standards Institute standard Z136.3, Safe Use of Lasers in Health Care. Finally, although it is common in some healthcare facilities to place gauze under external eye shields or use gauze alone over eyes during laser procedures, this practice poses an extreme risk to both patients and healthcare personnel. Therefore, we discuss why the use of gauze under eyewear for any laser procedures is not recommended, and instead, offer suggestions to consider when acquiring safe and comfortable patient eyewear.

The COVID-19 pandemic has necessitated a reorganization of healthcare delivery, shedding light on the many unrealized advantages telehealth has to offer. In addition to facilitating social distancing, minimizing the risk of pathogen exposure, and preserving healthcare resources, there are many benefits of utilizing this platform that can extend beyond the current pandemic, which will change the way healthcare is delivered for generations to come. With the rapid expansion of telehealth, we present data from our high-volume academic institution’s telehealth efforts, with a more focused analysis of plastic surgery. Although state legislation regarding telehealth varies greatly, we discuss challenges such as legal issues, logistical constraints, privacy concerns, and billing. We also discuss various advantages and the future direction of telehealth not only for plastic surgery but also its general utilization for the future of medicine in the United States.

Breast implants have evolved for decades. In 2011, the U.S. Food and Drug Administration identified an association between textured breast implants and breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). The purpose of this study was to identify the trends of textured implant use since that time.Maintenance of Certification tracer data were queried between 2011 and 2015 for cosmetic breast augmentation cases submitted by American Board of Plastic Surgery diplomates. A nested random effects logistic regression analysis was used to identify associations between variables.Eleven thousand seven hundred sixteen breast augmentations were performed by 880 unique surgeons. The overall proportion of cases using textured implants increased steadily from 2.3 percent in 2011 to 13.0 percent in 2015 (p0.001). The proportion of surgeons whose cases included both textured and smooth implants increased (from 6.2 percent to 24.3 percent), as did those using only textured implants (from 0.4 percent to 4.4 percent) (p0.001). Significance remained after controlling for form-stable implants, suggesting an alternative motivation for use of textured implants. Subglandular cases (20.5 percent) were more likely to use a textured implant than submuscular (8.4 percent) or dual-plane (7.8 percent) (p0.001) cases.Maintenance of Certification tracer data represent a random sampling of American Board of Plastic Surgery-certified plastic surgeons spanning the gamut of practice settings. Despite ongoing education regarding the association of BIA-ALCL with textured implants, American Board of Plastic Surgery diplomates have trended toward increased use of textured implants for cosmetic breast augmentation since 2011. This finding does not appear to be driven by the introduction of anatomical implants during the study period.
