RESUMEN

Introduction: The COVID-19 pandemic imparted an important shift in strategies postgraduate surgical programs use to recruit, interact with, and select medical students applying through the Canadian Resident Matching Service (CaRMS). With this unprecedented shift toward virtual applicant selection, this study sought to explore and analyze perspectives of the first cohort of program directors (PDs) and applicants who participated in this process. Methods: A cross-sectional survey study was designed using Google Forms for both PDs and applicants participating in the 2021 CaRMS surgical subspecialty selection process. Questions pertained to format and content of virtual engagement methods, the interview itself, as well as advice for future applicants. Results: Thirty-five PDs and 40 successful applicants (n = 75) participated in the study. Cost reduction was the most commonly reported benefit of online interviewing by PDs (85%), followed by efficiency (71%), enhanced resource management (49%), and ability to conduct more interviews (23%). Strong letters of reference (80%) and interview performance (74%) remained the most significant factors in virtual applicant selection. Attendance to virtual recruitment events did not increase the likelihood of offering interviews (n = 24, 69% of PDs), although the ability to perform in-person electives held tremendous value. Most applicants (90%) reported on virtual information sessions as the best method for learning about programs; work culture and environment were topics most valued as discussion points (90%). Successful applicants provided an average confidence of 76% regarding their suitability with their matched programs. Seventy-three percent of applicants (n = 29) had either a preference for virtual interviews or were equivocal, while 51.4% of PDs (n = 18) preferred interviews to be conducted virtually for future cohorts. Conclusion: Trainees are entering residency with confidence following a virtual selection process, and PDs feel confident in their selections. Although no clear consensus exists regarding preference for virtual or in-person interviews, several advantages for virtual resident selection exist. The influence of an in-person elective was found difficult to replace, regardless of interview format. The importance of applicant engagement with programs prior to interviews is highlighted and discussed with recommendations provided for best practices.


Introduction: La pandémie de COVID-19 a induit un important changement de stratégies de l'utilisation des programmes chirurgicaux de 3e cycle pour recruter, interagir avec les étudiants en médecine et sélectionner les étudiants déposant une candidature par le biais du CaRMS, le service d'affectation des résidents canadiens. Avec ce mouvement sans précédent vers une sélection virtuelle des candidats, l'étude a cherché à explorer et analyser les points de vue de la première cohorte de directeurs de programmes (DP) et de candidats ayant participé à ce processus. Méthodes: Une enquête transversale a été conçue à l'aide de Google Forms pour, à la fois, les DP et les candidats participant au processus de sélection de sous-spécialité chirurgicale 2021 du CaRMS. Des questions portaient sur le format et le contenu des méthodes de contact virtuelles, l'entretien proprement dit ainsi que sur des conseils pour les candidats futurs. Résultats: Trente-cinq DP et quarante candidats acceptés (n = 75) ont participé à l'étude. La réduction des coûts a été l'avantage des entretiens en ligne le plus souvent cité par les DP (85 %) suivie de l'efficacité (71 %), d'une meilleure gestion des ressources (49 %) et de la capacité à réaliser plus d'entretiens (23 %). De solides lettres de recommandation (80 %) et la performance au cours de l'entretien (74 %) restaient les facteurs les plus significatifs pour la sélection virtuelle des candidats. La participation aux événements virtuels de recrutement n'augmentait pas la probabilité d'offre d'un entretien (n = 24, 69 % des DP), même si la possibilité de réaliser des entretiens facultatifs en personne avait une valeur considérable. La plupart des candidats (90 %) ont indiqué que les séances d'information virtuelles étaient la meilleure méthode pour en savoir plus sur les programmes; la culture et l'environnement de travail étaient les thèmes ayant le plus de valeur comme sujets de discussion (90 %). Les candidats ayant réussi ont indiqué à 76 % qu'ils s'estimaient confiants sur le fait de bien correspondre aux programmes auxquels ils étaient affectés. Soixante-treize pour cent des candidats (n = 29) avaient une préférence pour les entretiens virtuels ou étaient dans le doute, tandis que 51,4 % des DP (n = 18) préféraient que les entretiens des cohortes futures soient menés virtuellement. Conclusion: Les stagiaires commencent leur résidence avec confiance après un processus de sélection virtuel et les DP se sentent confiants quant à leurs choix. Même s'il n'existe pas un franc consensus concernant une préférence pour les entretiens virtuels ou en face à face, la sélection à distance des résidents présente plusieurs avantages. L'influence d'un entretien optionnel en personne s'est avérée difficile à remplacer, quelle que soit la forme donnée à l'entretien. L'importance de l'engagement du candidat dans des programmes antérieurs aux entretiens est soulignée et discutée avec des recommandations fournies pour de meilleures pratiques.

RESUMEN

Introduction: Aesthetic liposuction represents one of the most commonly performed cosmetic procedures worldwide. The purpose of this article is to examine and synthesize reported complication rates and explore the analytical prospect of possible patient or procedure-related predictive factors associated with specific complications. Methods: A systematic review was performed using the Pubmed, Cochrane, and Embase databases in line with specific criteria set to ensure an accurate assessment of complication rates; extracted data was synthesized through a random-effects model and meta-analysis of proportions. Results: A total of 60 studies were included in the meta-analysis, representing 21,776 patients undergoing aesthetic liposuction. Most studies followed an observational design. The overall complication rate was 12% (95% confidence interval [CI] 8%, 16%). When stratifying according to specific complications, the incidence of contour irregularities was determined to be 2% (95% CI 1%, 2%), seroma 2% (95% CI 1%; 2%), hematoma 1% (95% CI 0%, 1%), surgical site infection 1% (95% CI 1%, 2%), fibrosis or induration 1% (95% CI 1%, 2%), and pigmentary changes 1% (95% CI 1%, 1%), among others. A meta-regression to identify patient- or procedure-related factors associated with greater complication rates proved infeasible given the nature of the available data. Conclusion: Overall, liposuction demonstrated a relatively low complication rate profile, however, a considerable degree of heterogeneity exists within the examined literature preventing the recognition of predictive risk factors. While this calls for efforts to establish consensus on unified methods of outcomes reporting, the present meta-analysis can serve to provide practitioners with an evidence-based reference to improve informed consent and inform clinical guidelines, specifically pertaining to the incidence of commonly encountered complications in aesthetic liposuction, of which presently available survey studies and database queries remain devoid.


Introduction : La liposuccion esthétique est l'une des procédures esthétiques le plus souvent réalisées dans le monde. L'objectif de cet article est d'étudier et synthétiser les taux de complications rapportés et d'explorer la possibilité d'analyse de possibles facteurs prédictifs liés aux patients ou à la procédure en association avec des complications spécifiques. Méthodes : Une revue systématique a été exécutée à partir des bases de données Pubmed, Cochrane et Embase selon un ensemble de critères spécifiques pour assurer une évaluation précise des taux de complications; les données extraites ont été synthétisées par un modèle d'effets aléatoires et une méta-analyse des pourcentages. Résultats : Un total de 60 études a été inclus dans la méta-analyse, représentant 21 776 patients subissant une liposuccion esthétique. La plupart des études étaient observationnelles. Le taux global de complications était de 12% (IC à 95% : 8% à 16%). Après stratification selon des complications spécifiques, les incidences suivantes ­ parmi d'autres ­ ont été établies : irrégularités de contour a été établi à 2% (IC à 95% : 1% à 2%), sérome 2% (IC à 95% : 1% à 2%), hématome 1% (IC à 95% : 0% à 1%), infection du site opératoire 1% (IC à 95% : 1% à 2%), fibrose ou induration 1% (IC à 95% : 1% à 2%) et modification de la pigmentation 1% (IC à 95% : 1% à 1%). Une méta-régression visant à identifier des facteurs liés aux patients ou à la procédure pour les taux de complications les plus élevés s'est avérée infaisable, compte tenu de la nature des données disponibles. Conclusion : Globalement, la liposuccion a montré un relativement bas profil en termes de taux de complications. Il existe cependant une hétérogénéité considérable dans les publications étudiées, empêchant d'identifier des facteurs de risque prédictifs. Cela appelle à des efforts en vue de l'établissement d'un consensus sur des méthodes uniformisées de déclaration des résultats, mais la présente méta-analyse peut permettre aux praticiens de disposer d'une référence basée sur des constatations probantes pour améliorer le consentement éclairé et enrichir les lignes directrices cliniques, en particulier pour ce qui concerne l'incidence des complications fréquemment vues dans la liposuccion esthétique. En effet, les études, enquêtes et bases de données actuellement disponibles en sont dépourvues.

RESUMEN

BACKGROUND: Despite increasing demand for breast capsular surgery to treat various benign and malignant implant-related pathologies, high-quality evidence elucidating complication profiles of capsulectomy and capsulotomy is lacking. OBJECTIVES: We provide the largest-scale analysis of associated outcomes and complications using the Tracking Operations and Outcomes for Plastic Surgeons (TOPS) database, and investigate clinical scenarios that may subject patients to increased risks for complications, most notably, extent of capsular surgery (complete vs partial), and index indication of implantation (aesthetic vs reconstructive). METHODS: An analysis of the TOPS database from 2008-2019 was performed. CPT codes were used to identify complete capsulectomy and partial capsulectomy/capsulotomy cases. Breast implant exchange procedures constituted procedural controls. RESULTS: In total, 7,486 patients (10,703 breasts) undergoing capsulectomy or capsulotomy were assessed. Relative to controls, capsulectomy (4.40% vs 5.79%; p = 0.0154), but not capsulotomy (4.40% vs 4.50%; p = 0.8876), demonstrated higher overall complication rates. Both capsulectomies (0.83% vs 0.23%; p < 0.0001) and capsulotomies (0.56% vs 0.23%; p = 0.0307) also had greater rates of seroma relative to controls. Subgroup analyses demonstrated that reconstructive patients, relative to aesthetic patients, experienced greater overall complications (6.76% vs 4.34%; p < 0.0001), and increased risks for seroma (1.06% vs 0.47%; p = 0.0016), dehiscence (0.46% vs 0.14%; p = 0.0059), surgical site infections (1.03% vs 0.23%; p < 0.0001), and implant loss (0.52% vs 0.23%; p = 0.0401). A detailed synthesis of 30-day outcomes, including all patient- and breast-specific complications, for both capsulectomy and capsulotomy, stratified according to all potential confounders, is presented herein. CONCLUSIONS: Surgeries on the breast capsule are overall safe, though complete capsulectomies and reconstructive patients were associated with significantly increased operative risks. Present findings will enhance patient selection, counselling, and informed consent.

RESUMEN

BACKGROUND: Large language models (LLMs) have revolutionized the way plastic surgeons and their patients can access and leverage artificial intelligence (AI). OBJECTIVES: The present study aims to compare the performance of 2 current publicly available and patient-accessible LLMs in the potential application of AI as postoperative medical support chatbots in an aesthetic surgeon's practice. METHODS: Twenty-two simulated postoperative patient presentations following aesthetic breast plastic surgery were devised and expert-validated. Complications varied in their latency within the postoperative period, as well as urgency of required medical attention. In response to each patient-reported presentation, Open AI's ChatGPT and Google's Bard, in their unmodified and freely available versions, were objectively assessed for their comparative accuracy in generating an appropriate differential diagnosis, most-likely diagnosis, suggested medical disposition, treatments or interventions to begin from home, and/or red flag signs/symptoms indicating deterioration. RESULTS: ChatGPT cumulatively and significantly outperformed Bard across all objective assessment metrics examined (66% vs 55%, respectively; P < .05). Accuracy in generating an appropriate differential diagnosis was 61% for ChatGPT vs 57% for Bard (P = .45). ChatGPT asked an average of 9.2 questions on history vs Bard's 6.8 questions (P < .001), with accuracies of 91% vs 68% reporting the most-likely diagnosis, respectively (P < .01). Appropriate medical dispositions were suggested with accuracies of 50% by ChatGPT vs 41% by Bard (P = .40); appropriate home interventions/treatments with accuracies of 59% vs 55% (P = .94), and red flag signs/symptoms with accuracies of 79% vs 54% (P < .01), respectively. Detailed and comparative performance breakdowns according to complication latency and urgency are presented. CONCLUSIONS: ChatGPT represents the superior LLM for the potential application of AI technology in postoperative medical support chatbots. Imperfect performance and limitations discussed may guide the necessary refinement to facilitate adoption.

RESUMEN

BACKGROUND: Social media platforms have come to represent integral components of the professional marketing and advertising strategy for plastic surgeons. Effective and consistent content development, however, remains technically demanding and time consuming, prompting most to employ, at non-negligible costs, social media marketing specialists for content planning and development. OBJECTIVES: In the present study, we aimed to investigate the ability of presently available artificial intelligence (AI) models to assist plastic surgeons in their social media content development and sharing plans. METHODS: An AI large language model was prompted on the study's objectives through a series of standardized user interactions. Social media platforms of interest, on which the AI model was prompted, included Instagram, TikTok, and X (formerly Twitter). RESULTS: A 1-year, entirely AI-generated social media plan, comprising a total of 1091 posts for the 3 aforementioned social media platforms, is presented. Themes of the AI-generated content proposed for each platform were classified in 6 categories, including patient-related, practice-related, educational, "uplifting," interactive, and promotional posts. Overall, 91 publicly recognized holidays and observant and awareness days were incorporated into the content calendars. The AI model demonstrated an ability to differentiate between the distinct formats of each of the 3 social media platforms investigated, generating unique ideas for each, and providing detailed content development and posting instructions, scripts, and post captions, leveraging features specific to each platform. CONCLUSIONS: By providing detailed and actionable social media content creation and posting plans to plastic surgeons, presently available AI models can be readily leveraged to assist in and significantly alleviate the burden associated with social media account management, content generation, and potentially patient conversion.

RESUMEN

Objectives: Metacarpal non-unions are complex hand defects that can lead to severe hand impairment. Treatment may require the use of artificial or autologous bone grafts. This systematic review aims to describe the outcomes of bone grafting following metacarpal non-union in an attempt to establish an optimal therapeutic protocol for this complication. Methods: A systematic review was conducted in adherence with PRISMA guidelines. Data collection and analysis were performed in duplicate and confirmed by a third investigator. Our primary outcomes focused on radiological time to bone fusion and rates of non-union. Additionally, functional outcomes and complications were analyzed as means of central tendency. Results: Eighteen studies were included in the systematic review, accounting for a total of 47 patients. The average follow-up time was 12.4 months. Fourteen studies analyzed radiological outcomes, with atrophic non-union representing the most common type. The time to bone fusion, assessed radiologically, following bone graft was an average of 6.9 months (n = 14), with a 100% rate of union in 42 patients. Regarding patient-reported pain improvement, 76% of patients experienced pain relief. Moreover, all patients reported a complete subjective return to baseline hand function. Adverse events, limited to hematoma and seroma, were seen in three patients, representing a complication rate of 11.8% in the examined population. Conclusions: Metacarpal non-union can be treated successfully via vascularized and non-vascularized bone grafting. Based on the available evidence, bone grafts demonstrate favorable union rates, post-operative pain reduction, hand function recovery, earlier bone fusion times, and minimal complications in the context of metacarpal non-union management.

RESUMEN

INTRODUCTION: Large language models (LLM) have revolutionized the way humans interact with artificial intelligence (AI) technology, with marked potential for applications in esthetic surgery. The present study evaluates the performance of Bard, a novel LLM, in identifying and managing postoperative patient concerns for complications following body contouring surgery. METHODS: The American Society of Plastic Surgeons' website was queried to identify and simulate all potential postoperative complications following body contouring across different acuities and severity. Bard's accuracy was assessed in providing a differential diagnosis, soliciting a history, suggesting a most-likely diagnosis, appropriate disposition, treatments/interventions to begin from home, and red-flag signs/symptoms indicating deterioration, or requiring urgent emergency department (ED) presentation. RESULTS: Twenty-two simulated body contouring complications were examined. Overall, Bard demonstrated a 59% accuracy in listing relevant diagnoses on its differentials, with a 52% incidence of incorrect or misleading diagnoses. Following history-taking, Bard demonstrated an overall accuracy of 44% in identifying the most-likely diagnosis, and a 55% accuracy in suggesting the indicated medical dispositions. Helpful treatments/interventions to begin from home were suggested with a 40% accuracy, whereas red-flag signs/symptoms, indicating deterioration, were shared with a 48% accuracy. A detailed analysis of performance, stratified according to latency of postoperative presentation (<48hours, 48hours-1month, or >1month postoperatively), and according to acuity and indicated medical disposition, is presented herein. CONCLUSIONS: Despite promising potential of LLMs and AI in healthcare-related applications, Bard's performance in the present study significantly falls short of accepted clinical standards, thus indicating a need for further research and development prior to adoption.

RESUMEN

BACKGROUND: The rapidly evolving field of artificial intelligence (AI) holds great potential for plastic surgeons. ChatGPT, a recently released AI large language model (LLM), promises applications across many disciplines, including healthcare. OBJECTIVES: The aim of this article was to provide a primer for plastic surgeons on AI, LLM, and ChatGPT, including an analysis of current demonstrated and proposed clinical applications. METHODS: A systematic review was performed identifying medical and surgical literature on ChatGPT's proposed clinical applications. Variables assessed included applications investigated, command tasks provided, user input information, AI-emulated human skills, output validation, and reported limitations. RESULTS: The analysis included 175 articles reporting on 13 plastic surgery applications and 116 additional clinical applications, categorized by field and purpose. Thirty-four applications within plastic surgery are thus proposed, with relevance to different target audiences, including attending plastic surgeons (n = 17, 50%), trainees/educators (n = 8, 24.0%), researchers/scholars (n = 7, 21%), and patients (n = 2, 6%). The 15 identified limitations of ChatGPT were categorized by training data, algorithm, and ethical considerations. CONCLUSIONS: Widespread use of ChatGPT in plastic surgery will depend on rigorous research of proposed applications to validate performance and address limitations. This systemic review aims to guide research, development, and regulation to safely adopt AI in plastic surgery.

RESUMEN

INTRODUCTION: ChatGPT represents a potential resource for patient guidance and education, with the possibility for quality improvement in healthcare delivery. The present study evaluates the role of ChatGPT as an interactive patient resource, and assesses its performance in identifying, triaging, and guiding patients with concerns of postoperative complications following facelift and neck lift surgery. METHODS: Sixteen patient profiles were generated to simulate postoperative patient presentations, with complications of varying acuity and severity. ChatGPT was assessed for its accuracy in generating a differential diagnosis, soliciting a history, providing the most-likely diagnosis, the appropriate disposition, treatments/interventions to begin from home, and red-flag symptoms necessitating an urgent presentation to the emergency department. RESULTS: Overall accuracy in providing a complete differential diagnosis in response to simulated presentations was 85%, with an accuracy of 88% in identifying the most-likely diagnosis after history-taking. However, appropriate patient dispositions were suggested in only 56% of cases. Relevant home treatments/interventions were suggested with an 82% accuracy, and red-flag symptoms with a 73% accuracy. A detailed analysis, stratified according to latency of postoperative presentation (<48 h, 48 h-1 week, or >1 week), and according to acuity of complications, is presented herein. CONCLUSIONS: ChatGPT overestimated the urgency of indicated patient dispositions in 44% of cases, concerning for potential unnecessary increase in healthcare resource utilization. Imperfect performance, and the tool's tendency for overinclusion in its responses, risk increasing patient anxiety and straining physician-patient relationships. While artificial intelligence has great potential in triaging postoperative patient concerns, and improving efficiency and resource utilization, ChatGPT's performance, in its current form, demonstrates a need for further refinement before its safe and effective implementation in facial aesthetic surgical practice.

RESUMEN

BACKGROUND: Hematoma is the most common complication after facelift surgery. Hypertension is the major risk factor for hematoma following facelift. Measures taken to reduce systolic blood pressure perioperatively significantly reduce the risk of hematoma. There is evidence that treating systolic blood pressure of 140 mmHg or above reduces hematoma; there were no studies to date in which systolic blood pressures below 120 mmHg had been evaluated. OBJECTIVES: To assess the safety and efficacy of maintaining systolic blood pressures of 120 mmHg or less postoperatively to reduce hematoma after facelift. METHODS: A retrospective chart review of a single surgeon's series of facelift procedures from January 2004 to July 2018 was undertaken. Implementation of a more stringent perioperative blood pressure protocol (maintaining a systolic blood pressure of less than 120 mmHg postoperatively) was initiated in January of 2013, dividing patients into 2 groups. RESULTS: A total of 502 consecutive patients who underwent a facelift by F.N. were included in the study. A total of 319 patients underwent a facelift before 2013, and a total of 183 patients underwent a facelift in 2013 or later. Overall, a total of 13 hematomas occurred during the entire 15-year study period (2.59%), of which 12 occurred before the implementation of a strict blood pressure regimen (3.76%), and only 1 occurred after the new protocol (0.5%). There were no adverse events related to the lower blood pressure. CONCLUSIONS: Treating systolic blood pressure greater than 120 mmHg postoperatively is a safe and effective method for reducing the risk of hematoma after facelift.

RESUMEN

BACKGROUND: Prepectoral breast reconstruction has recently experienced a resurgence in popularity. However, in direct-to-implant (DTI) reconstruction, there is no opportunity for capsular modifications before final implant insertion. Implant pocket and breast shape are thus maintained, initially, solely by the mastectomy skin flaps, and eventually, by attachments of the periprosthetic capsule. The present study aims to quantify changes in breast geometric measurements over time following DTI prepectoral breast reconstruction. METHODS: A retrospective chart review was performed for patients who underwent bilateral prepectoral DTI reconstruction performed by a single surgeon from June of 2016 to January of 2018. Patients followed for more than 2 years were included. Yearly standardized frontal photographs were analyzed, and nipple-to-midline, sternal notch-to-nipple, and midclavicle-to-lower pole measurements were obtained. Patient demographics, operative details, and complications were documented. RESULTS: A total of 72 breasts (38 women) undergoing direct-to-implant, prepectoral breast reconstruction were included in the final analysis. Acellular dermal matrix was used in 56 breasts only (78.9%) for anterior coverage. The average change in nipple-to-midline distance after 2 years decreased by 0.41 cm (range, -2.00 to 2.97 cm), sternal notch-to-nipple distance decreased by 0.62 cm (range, -4.98 to 5.4 cm), and midclavicle-to-lower pole distance decreased 0.10 cm superiorly (range, -6.07 to 3.6 cm). In breasts that underwent postmastectomy radiation therapy, the average changes were -0.08, -0.43, and -0.56 cm, respectively. No patient in this cohort had severe malposition requiring further surgery. CONCLUSIONS: The present study provides insight into geometric breast measurements following prepectoral breast reconstruction at 2-year follow-up. The minimal breast shape changes observed demonstrate the feasibility of prepectoral DTI reconstruction with or without the use of acellular dermal matrix. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMEN

BACKGROUND: Adverse events arising in patients with breast implants during mammography reported by the Food and Drug Administration include implant rupture, pain, and impaired visualization. However, data supporting these claims were collected in 2004, and since, newer implant generations have been developed with overall rate of implantation increasing by 48%. OBJECTIVES: This article aims to determine the current incidence of implant-related adverse events arising during mammography. METHODS: We analyzed reports regarding silicone and saline breast implants published in the Food and Drug Administration Manufacturer and User Facility Device Experience database between 2008 and November 2018. Search terms included "mammogram," "mammography," "radiograph," "breast cancer screening," "breast cancer test," and "x-ray." RESULTS: Of the 20 539 implant-related adverse events available in the Manufacturer and User Facility Device Experience database, 427 were retrieved using our search strategy and 41 were related to mammography. Thirty-five of identified cases (85.4%) reported implant rupture, of which 19 (54.3%) were confirmed by a healthcare professional, 9 (25.7%) were clinically confirmed by saline implant deflation, and 7 (20.0%) were unverified reports by patients. Sixteen ruptures (45.7%) occurred with silicone implants, whereas 19 ruptures (54.3%) occurred with saline. Other adverse events included pain (29.3%), change in implant appearance (14.6%), and swelling (7.3%). CONCLUSIONS: Although implant rupture, pain, change in implant appearance, and swelling may occur, minimal implant-related adverse events arise during mammography. Given the extremely low reported risk of implant rupture, this should neither prevent patients from adhering to breast cancer screening programs nor deter patients from seeking breast implants. Patients should be aware of these reported risks and discuss screening options with their breast cancer screening team.

RESUMEN

BACKGROUND: Progressive hemifacial atrophy is a rare disorder characterized by gradual unilateral soft-tissue atrophy in the face, which may also include clinically significant degeneration of underlying muscle and bone. In recent years, there has been a growing body of evidence regarding different soft-tissue reconstructive strategies in progressive hemifacial atrophy and the impact of intervention timing on disease progression. This article provides a comprehensive synthesis of the latest evidence to guide optimal management. METHODS: A comprehensive multidatabase search was performed through April of 2020 using relevant search terms to identify clinical studies. Outcomes, complications, and disease- and patient-related indications pertaining to different soft-tissue reconstructive strategies in progressive hemifacial atrophy were collected and critically appraised. RESULTS: Thirty-five articles reporting on a total of 824 progressive hemifacial atrophy patients were evaluated; 503 patients (61 percent) were managed by microvascular free flaps, 302 patients (37 percent) were managed by autologous fat grafts, and 19 patients (2 percent) were managed by pedicled flaps. A detailed synthesis of outcomes is presented in this article, as is a comparative evaluation of different microvascular free flap options. CONCLUSIONS: Soft-tissue reconstruction in progressive hemifacial atrophy remains an evolving field. Operative decision-making is often multifaceted, and guided by specific volumetric, aesthetic, and functional deficiencies. Serial fat grafting is the primary modality used for patients with mild soft-tissue atrophy, whereas microvascular free flaps widely remain the treatment of choice for reconstruction of large-volume defects. There exists a growing role of graft supplementation to improve fat graft survival, whereas recent evidence demonstrates that early intervention may help curb disease progression.

RESUMEN

Background: Although plastic surgeons commonly perform capsulectomies for a variety of peri-prosthetic capsular conditions, the safety of capsulectomy remains unknown, and the literature lacks evidence describing its morbidity and complication rates for patients inquiring about its associated risks. Objectives: The present study aims to identify and define the complication rates associated with capsulectomies. Methods: An analysis of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was performed between the years 2015 and 2018. All information pertaining to demographics, patient-related information, surgical indications, procedure-related information, outcomes, and complications were assessed. Results: The study identified 2231 cases of surgeon-reported capsulectomies; indications most commonly reported included capsular contracture (n = 638, 28.6%) and breast implant rupture (n = 403, 18.1%). In total, 141 patients (6.32%) were hospitalized for longer than 1 postoperative day (range, 2-28 days), while the overall complication rate was 3.0% (n = 67/2231 patients). Incidence of minor complications, representing superficial surgical site infections, was 0.8%, while the major complication rate was 2.24%. These included 7 cases of deep surgical site infections (0.3%), 19 organ space infections (0.9%), and 8 cases of wound dehiscence (0.4%). Eight patients developed sepsis (0.4%); 6 patients required transfusions (0.3%); 1 case of postoperative pneumonia and 1 myocardial infarction were also identified (n = 1 each, 0.0%). The overall reoperation and readmission rates were 2.0%, representing a readmission rate of 66% among patients with complications. Conclusions: The present study provides the first estimate of the incidence of complications associated with capsulectomies. Although the NSQIP database contains significant limitations, the data presented herein describe a complication profile that plastic surgeons can share with their patients during informed consent.

RESUMEN

Loss-of-function mutations in the MEN1 tumor-suppressor gene cause the multiple endocrine neoplasia type 1 syndrome. Menin, the MEN1 gene product, is expressed in many tissues, including bone, where its function remains elusive. We conditionally inactivated menin in mesenchymal stem cells (MSCs) using paired-related homeobox 1 (Prx1)-Cre and compared resultant skeletal phenotypes of Prx1-Cre;Men1 f/f menin-knockout mice (KO) and wild-type controls using in vivo and in vitro experimental approaches and mechanics simulation. Dual-energy X-ray absorptiometry demonstrated significantly reduced bone mineral density, and 3-dimensional micro-CT imaging revealed a decrease in trabecular bone volume, altered trabecular structure, and an increase in trabecular separation in KO mice at 6 and 9 months of age. Numbers of osteoblasts were unaltered, and dynamic histomorphometry demonstrated unaltered bone formation; however, osteoclast number and activity and receptor activator of NF-κB ligand/osteoprotegerin (RANKL/OPG) mRNA profiles were increased, supporting increased osteoclastogenesis and bone resorption. In vitro, proliferative capabilities of bone marrow stem cells and differentiation of osteoblasts and mineralization were unaltered; however, osteoclast generation was increased. Gross femur geometrical alterations observed included significant reductions in length and in mid-metaphyseal cross-sectional area. Atomic force microscopy demonstrated significant decreases in elasticity of both cortical and trabecular bone at the nanoscale, whereas three-point bending tests demonstrated a 30% reduction in bone stiffness; finite element analysis showed morphological changes of the femur microgeometry and a significantly diminished femur flexural rigidity. The biomechanical results demonstrated the detrimental outcome of the accelerated osteoclastic bone resorption. Our studies have a twofold implication; first, MEN1 deletion from MSCs can negatively regulate bone mass and bone biomechanics, and second, the experimental and computational biomechanical analyses employed in the present study should be applicable for improved phenotypic characterization of murine bone. Furthermore, our findings of critical menin function in bone may underpin the more severe skeletal phenotype found in hyperparathyroidism associated with loss-of-function of the MEN1 gene. © 2022 The Authors.
