Glenohumeral Dysplasia Following Brachial Plexus Birth Injuries: A Review.

BACKGROUND AND OBJECTIVES: Despite the high morbidity associated with glenohumeral dysplasia (GHD) in children with brachial plexus birth injuries, the progression of this condition often remains unnoticed, even after correcting for the underlying brachial plexus birth injuries. GHD, driven by a multifactorial process involving disruptions in both direct and indirect neural regulation of bony and muscular structures, can lead to intermittent or permanent shoulder mobility imbalances, significantly impacting the quality of life of those affected. Recent research efforts are increasingly directed toward identifying the root causes, managing the deformity, and determining effective treatment options for correcting GHD. METHODS: A comprehensive search strategy was used by the authors to identify relevant literature relating to the progression, pathoanatomy, clinical presentation, and management of GHD following brachial plexus birth injuries across various search engines, such as PubMed, Scopus, and Embase. Considering the topic's interdisciplinary nature, articles were retrieved from both neurosurgical and orthopaedic journals to enrich the review. RESULTS: Given the challenges in managing patients with brachial plexus birth injuries, a multidisciplinary care team consisting of certified occupational hand therapists, neurosurgeons, plastic surgeons, and orthopedic surgeons, specializing in brachial plexus injuries should be advocated for. The aim of this collaborative effort is to correct brachial plexus birth injuries and prevent the persistence of GHD. CONCLUSION: As research continues to focus on understanding the complexities of this condition, the aim of this review article is to summarize the current literature on the course of brachial plexus birth injury and the development of GHD. By doing so, we hope to provide neurosurgeons with the necessary knowledge and essential tools needed to identify and effectively treat GHD during management of brachial plexus birth injuries.

Mapping the Landscape of Brachial Plexus Birth Injury Research: A Comprehensive Bibliometric Study.

Facial Masculinization Surgery: An Analysis of Interest Trends Using Search Term Analysis.

INTRODUCTION: Facial masculinization surgery (FMS) is increasingly popular among cisgender and transgender men. The benefits of FMS are focused on facial identity and have been proven to decrease gender dysphoria in this population. Previous research showed increasing interest in gender affirmation surgery and facial feminization surgery, but the prevalence of FMS has not been explored. It is difficult to find these data based on surgical records alone because institutions do not have standardized methods of reporting and lack publications in the field. Our study aimed to analyze public interest in FMS by using worldwide Google Trends to quantify these trends. METHODS: A worldwide Google Trends search was completed from January 1, 2008, to December 31, 2022, for terms focused on FMS. Then, search terms were analyzed for nonfacial masculinization procedures and were aggregated. Lastly, a PubMed search was conducted for the terms "transgender" and "facial masculinization" from January 1, 2008, to December 31 st , 2022, to compare publication rates. RESULTS: Our data showed an increasing interest in FMS through Google search trends since the year 2008. A similar trend was demonstrated for non-FMS gender-affirming terms. PubMed analysis showed "transgender" medicine publishing rates were approximately 39.65 times greater than "facial masculinization" publishing rates, although "facial masculinization" medicine did produce a positive trend over the study period of approximately 4 publications per year. The medical literature on transgender surgeries rapidly outpaces publications specifically focusing on FMS. CONCLUSION: Our study showed increasing interest in gender affirmation surgery over time, particularly FMS. These increasing trends should encourage greater scientific exploration of FMS and research to properly quantify and assess surgical outcomes in this special population. Additional educational interventions for both the general public and medical providers, to increase awareness of unique challenges that impact this community and highlight changes in health care coverage over time, should be created to keep pace with increasing patient demand and address the physical, systemic, and psychosocial issues faced by people who identify as transgender.

Trends, Gaps, and Collaboration in Facial Transplantation: A Bibliometric Study.

Facial transplantation (FT) has advanced extensively over the past two decades, with over 40 transplants performed to date. Over this time, the FT literature has evolved as well, from early discussions on ethics and feasibility of FT to functional outcomes reports more recently. We aimed to evaluate the entire body of FT literature to identify trends in publications over time in addition to current existing gaps in the field. Methods: We conducted a comprehensive bibliometric analysis of the published FT literature from 1994, the first year FT was mentioned in the literature, through July 2020. Co-authorship and keyword information were analyzed using VOSviewer. Articles were manually categorized based on keywords and their aim to provide insight on trends. Results: A total of 2182 articles were identified. Analysis identified the top 50 publishing authors in the field and demonstrated co-authorship linkage between 84.8% of the top 1000 authors. Clinical surgical techniques, protocols, and experiments were the most frequently published category. Within clinical outcomes, immunologic outcomes were most frequent, while psychosocial were the lowest. Gaps were identified in long-term outcomes reporting and patient-reported outcomes, with physician-reported outcomes heavily outweighing patient-reported outcomes. Conclusions: As the field continues to evolve, rigorous tracking of publication patterns over time will encourage development of a more robust evidence base, identify gaps in the published literature, and highlight opportunities to enhance collaboration in the field. This data will provide surgeons and research institutions with information to further improve this life-changing procedure.

Is Digital Animation Superior to Text Resources for Facial Transplantation Education? A Randomized Controlled Trial.

BACKGROUND: Facial transplantation is a complex surgical procedure that requires education of medical professionals, patients, and the general public. The objective of this randomized controlled trial was to compare the educational efficacy of facial transplantation digital animation versus text resources for teaching medical students a complex surgical procedure and its applicable anatomical and surgical principles. METHODS: Medical student volunteers were recruited and prospectively randomized to an animation or a text group. Students completed preintervention and postintervention assessments of confidence and knowledge of head and neck anatomy and facial transplantation. Student Evaluations of Educational Quality survey assessed student satisfaction with both tools following study crossover. Knowledge assessment was developed using National Board of Medical Examiners guidelines and content validated by four experts. The Cohen d statistic was used to measure the effect size of each intervention. RESULTS: Thirty-six students were assigned randomly to the animation group (n = 19) or the text (n = 17) group. Postintervention analysis demonstrated significantly higher performance scores in the animation group compared to the text group (p = 0.029). The animation group had a larger effect size (Cohen d = 1.96 versus 1.27). Only students in the animation group reported significantly improved confidence in head and neck anatomy after the intervention (p = 0.002). Both groups demonstrated significantly increased postintervention confidence in knowledge of facial transplantation (p < 0.001). Satisfaction scores revealed that students significantly favored the animation resource (p < 0.001). CONCLUSIONS: Animation can be an effective tool for facial transplantation education and results in improved student knowledge, confidence, and satisfaction compared to text resources. Facial transplantation can also be used as an educational framework for teaching medical students anatomical and surgical principles.

Have We Achieved Optimal Skin Color Matching in Partial Facial Transplantation? A Survey Study of the General Public and Medical Professionals.

BACKGROUND: Skin color matching is an essential factor in achieving optimal aesthetic outcome in partial facial transplantation. However, there is no published literature evaluating the success of color matching to date. Furthermore, a medical professional's perception of an optimal color match may not necessarily translate to that of the general public. The purpose of our study was to evaluate skin color matching between the donor allograft and recipient native tissue in partial facial transplantations to determine the level of success perceived by the general public and medical professionals. METHODS: Published photographs of partial face transplant recipients were used to create a survey where recipient native and donor allograft skin samples were juxtaposed. Thirty-three members of the general public and 30 medical professionals were asked to rate skin color match on a scale from "excellent match" to "not a match." RESULTS: Overall, 47% of given ratings were positive, indicating an "excellent" or "good match," and 53% of ratings were negative, indicating a "poor match" or "lack of match" between the skin sample pairings shown. Of the 19 partial face transplant patients who were rated, 9 patients received >50% positive ratings, and 10 patients received <50% positive ratings. Medical professionals consistently gave more positive ratings, with statistically significant differences in 7 of the 19 rated patients (P < 0.05). CONCLUSION: The results suggest that there is need for improvement in color matching in partial facial transplantation, and that the general public is more critical of skin color matching compared to medical professionals.

Guiding Strategies for the Future of Vascularized Composite Allotransplantation: A Systematic Review of Organ Donation Campaigns.

BACKGROUND: Since the 1990s, the field of vascularized composite allotransplantation has gained momentum, offering unprecedented solutions for patients with defects not amenable to autologous reconstruction. As with solid organ donation, the vascularized composite allotransplant donor pool remains limited. This systematic review identifies past successes and failures in organ donation campaigns to guide future strategies for expanding vascularized composite allotransplant donation. METHODS: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Three databases (PubMed/MEDLINE, PsycINFO, and Embase) were searched through July 31, 2019. The study compiled solid organ and vascularized composite allotransplant campaigns that aimed to increase donor registration. Articles depicting the current state of vascularized composite allotransplant donation were also assessed. RESULTS: Of an initial 3318 articles identified, 40 were included. Six articles described direct mail or print interventions, 10 depicted Web-based interventions, 13 dealt with interpersonal interventions, and seven used multimodal interventions. Four articles described the current state of vascularized composite allotransplant donation. A qualitative synthesis was conducted. The authors found that social media campaigns can have a robust but fleeting effect on registration trends and that interpersonal interventions are effective at increasing registration rates. In addition, the opportunity for participants to immediately register as organ donors, by means of either return mail, in-person, or online, is vital to campaign success. CONCLUSIONS: Public organ donation campaigns have had success in increasing organ donor registration rates, particularly through the use of social media and interpersonal interventions that allow for immediate registration. Synthesizing this information, we propose a multimodal campaign to expand the vascularized composite allotransplant donor pool.

Public Perceptions of Cross-Sex Vascularized Composite Allotransplantation.

BACKGROUND: Cross-sex vascularized composite allotransplantation has been performed in cadaveric facial transplantation and clinical extremity transplantation. Understanding the challenge of appropriate donor-recipient matching, this study sought to characterize the public's perception of cross-sex vascularized composite allotransplantation. METHODS: Participants were surveyed in New York City. Data collected included demographics and willingness to donate vascularized composite allografts (VCAs) of various types. Similar questions were asked in the context of same-sex and cross-sex donation. RESULTS: A total of 101 participants (male: 56.4%; age ≤35 years: 62.4%) were surveyed. The majority expressed willingness to donate to recipients of a different sex (hand: 78.2%, face: 56.4%, penis or uterus: 69.3%, lower limb: 81.2%, abdominal wall: 80.2%, larynx: 81.2%, and solid organs: 85.2%). Among VCAs, willingness to donate facial allografts was significantly different in same-sex versus cross-sex contexts (64.4% vs 56.4%; P = 0.008). Participants were also significantly more likely to donate VCAs to same-sex recipients on behalf of themselves versus loved ones (P < 0.05). There was significantly lower willingness to receive cross-sex versus same-sex facial (P = 0.022) and genital allografts (P = 0.022). Education on the preservation of recipient masculinity or femininity in cross-sex facial transplantation increased participants' willingness to receive a cross-sex face transplant from 56.4% to 71.3% (P = 0.001). CONCLUSIONS: This study highlights the urban public's acceptance of VCA donation or reception regardless of sex mismatch. There is increased willingness to receive a cross-sex face transplant after education, highlighting opportunities for future focused interventions to increase public awareness and ultimately the donor pool.

Establishing a Clinically Applicable Methodology for Skin Color Matching in Vascularized Composite Allotransplantation.

Skin color matching in vascularized composite allotransplantation (VCA) is an important determinant of aesthetic outcomes. The process of color matching is infrequently described in the literature. The Pantone SkinTone Guide (PSTG) is a handheld tool comprised of realistic skin tone swatches with a corresponding virtual swatch system. A color match acceptability threshold (AT) is defined as the point beyond which >50% of observers deem a given skin tone pairing as unacceptable. In this study, color match acceptability thresholds were developed using the PSTG to help standardize donor-recipient color matching. Four representative colors were chosen across the skin tone spectrum. These standard colors were used to develop a survey asking participants to determine the acceptability of color pairings. Using survey results, ATs were determined for changes in lightness, undertone, and lightness and undertone combined for each of the standard colors. Inter- and intra-rater reliability were determined using Fleiss's Kappa. Participants were more critical of skin tone pairings on the darker versus the lighter end of the spectrum, as evidenced by higher thresholds observed for lighter sample pairs. Additionally, observers were more critical of differences in skin lightness compared with differences in undertone. Intra-rater reliability was fair to substantial, and inter-rater reliability was fair to moderate. The PSTG can be used as a clinical tool to improve the aesthetic outcomes of skin-containing vascularized composite allotransplantation procedures by optimizing donor-recipient skin color matching. This can allow clinicians to complement visual judgment with quantitative reference.
