Technical Pearls and Pitfalls of Facial Feminization Surgery: A Review of Techniques From a Single Institutional Practice.

BACKGROUND: Facial feminization surgery (FFS) is an emerging practice that falls under the broader umbrella of gender-affirming surgery. Various approaches exist to feminize the face, yet few published articles describe in detail the techniques of each component procedure. Considering the diversity of interventions employed, the objective of this manuscript is to highlight FFS techniques utilized by the senior author and create a corresponding media gallery. METHODS: All patients with the diagnosis of gender dysphoria that were referred to the senior author for FFS consultation between June 2017 and August 2022 were reviewed. Data were retrospectively collected from electronic medical records according to the institutional review board (IRB)-approved study protocol. Data collected and analyzed included demographics, operative documentation, and postoperative follow-up. Multimedia material was collected intraoperatively and postoperatively. RESULTS: A total of 231 patients underwent 262 operations with a total of 1224 FFS procedures. The average follow-up time was 7.7 ± 11 months. Out of the 262 operations, 24 (9.2%) patients experienced minor complications, including 3 (1.1%) with wound dehiscence, 13 (5.0%) with hematomas, and 14 (5.3%) with postoperative infection requiring antibiotics. Of those, 3 (1.1%) required a return to the operating room for washout or removal of malar implants. CONCLUSION: Although there is a consensus on the fundamental surgical principles to achieve adequate feminization of the facial architecture, the specific techniques to do so differ according to individual practices. As techniques diverge, so do their risk profiles and outcomes; techniques must, thus, align with patients' interventional goals. The material presented here is one of many that can support trainees and junior surgeons as they build a gender-affirming practice.

Meta-Analysis of Validated Quality of Life Outcomes Following Voice Feminization in Transwomen.

OBJECTIVES: For transwomen undergoing voice feminization interventions, fundamental frequency (F 0 ; vocal pitch) is a commonly reported functional outcome measure in the literature. However, F 0 may not correlate well with improvement in quality of life (QoL). Several validated voice-related QoL instruments have been used to assess QoL improvement in these patients, yet there is no consensus on the most appropriate instrument. This systematic review and meta-analysis aimed to assess the relationship between change in F 0 and QoL improvement following voice feminization, and to compare validated QoL instruments commonly used in this population. DATA SOURCES: PubMed, Cochrane, and Embase. REVIEW METHODS: A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Primary studies of transwomen undergoing voice feminization, reporting validated QoL outcomes were included. Meta-analyses for associations between mean change in QoL score and mean change in F 0 , as well as variations in mean change in QoL score by QoL instrument, were performed using a multilevel mixed effects model. RESULTS: No statistically significant correlation was found between change in F 0 and QoL score improvement post-intervention. Different validated instruments showed statistically significant variation in QoL score change, with the Trans Women Voice Questionnaire (TWVQ) capturing a greater improvement in QoL score relative to other instruments. CONCLUSIONS: Lack of correlation between changes in F 0 and QoL improvement further supports that F 0 alone is insufficient to assess the efficacy of voice feminizing interventions. Validated QoL measures are useful adjuncts. Of these, the TWVQ appears to be the most sensitive for measurement of QoL improvement following voice feminization.

Comparative Outcomes of Malar Implants Versus Fat Transfer to Cheeks Among Transfeminine Individuals Undergoing Malar Augmentation.

BACKGROUND: Malar augmentation is a key procedure sought out by transfeminine individuals seeking to feminize their facial appearance. Different surgical techniques have been described in the literature including fat transfer to the cheeks and malar implant placement. Because of the paucity of information in the literature, there is no consensus on best practices for this procedure. The objective of our study is to determine the effectiveness and safety of malar implants as compared with fat transfer to the cheeks in transfeminine individuals. METHODS: We examined all patients with the diagnosis of gender dysphoria that were referred to the senior author seeking consultation for feminizing facial procedures between June 2017 and August 2022. Patients who underwent fat transfer to the cheeks or malar implant placement were included in our study. We reviewed the electronic medical record of each patient, and we retrieved and analyzed data regarding demographics, medical and surgical history, operative dictations, clinic notes, and postoperative follow-up. Univariate analysis was used to assess for differences in postoperative complications between these 2 groups. RESULTS: We identified 231 patients underwent feminizing facial gender affirming surgery, with 152 patients receiving malar augmentation through malar implants or fat grafting. One hundred twenty-nine patients (84.9%) underwent malar implant placement and 23 (15.1%) underwent fat grafting to the cheeks. The mean follow-up time was 3.6 ± 2.7 months. Patient satisfaction was greater in the malar implant group (126/129, 97.7%) compared with the fat transfer group (20/23, 87%, P < 0.045). Two patients who received implants (1.8%) experienced postoperative complications. No patient undergoing fat transfer experiences similar adverse outcomes. Nevertheless, the difference was not statistically significant (P = 1.00). CONCLUSIONS: Our findings support the contention that malar implants are a safe alternative for malar augmentation among transfeminine individuals. While autologous fat transfer to the cheek is an indispensable option in patients requiring minor malar enhancement, malar implants offer a more permanent option with a better aesthetic outcome in patients requiring major malar enhancement. To minimize postoperative complications, surgeons should emphasize patient compliance with postoperative directions.

Systematic Review and Meta-analysis of Facial Anthropometric Variations Among Cisgender Females of Different Ethnicities: Implications for Feminizing Facial Gender Affirming Surgery.

BACKGROUND: Feminizing Facial Gender-Affirming Surgery (FFGAS) is gaining popularity among the diverse population of patients impacted by gender incongruence. However, most studies examining facial femininity are based on Caucasians. Thus, it is unclear if ethnic differences exist in anthropometric measures relevant to FFGAS procedures. This study aims to analyze ethnic anthropometric variations in the cisgender female face to identify differences that are potentially relevant to FFGAS. METHODS: A systematic review and meta-analysis of the PubMed, EMBASE, and Cochrane databases was performed following PRISMA guidelines on June 25, 2021. Original studies reporting facial anthropometry in cisgender women were included. Anthropometric measures of interest included mandibular and zygomatic width, facial and forehead height, and nasolabial angle. A meta-analysis was performed using a linear mixed-effects model for each anthropometric measure. RESULTS: A total of 1246 abstracts were screened, yielding 21 articles that met the inclusion criteria. Facial anthropometric data of 4792 cisgender females of 16 different ethnicities were analyzed. This meta-analysis demonstrated that compared with Caucasian cisgender women, Japanese, Chinese, and Korean cisgender women had a wider mandible (Japanese +20.13 mm [SE 4.43, P <0.001, P value adjusted for multiple comparisons (p-adj)=0.002], Chinese +16.22 mm [SE 4.39, P =0.002, p-adj=0.013]; and Korean +14.46 mm [SE 3.97, P =0.002, p-adj=0.014]). Further, when compared with Caucasian cisgender women, Chinese cisgender women demonstrated a larger zygomatic width, African American cisgender women tended to have smaller nasolabial angles, and Indian and Japanese cisgender women tended to have a smaller and larger facial height, respectively. However, following P value adjustment for multiple comparisons, these differences were not found to be statistically significant. CONCLUSIONS: We found that mandibular width tends to be greater for Japanese and Chinese cisgender women relative to Caucasian cisgender women. This data may be useful in counseling patients during preoperative evaluations ahead of mandibular reduction. No other anthropometric features were found to be significantly different among the ethnic groups studied. This portends that current approaches to FFGAS, which emphasize patient-specific needs and maintenance of a harmonious appearance, may require minimal or no adjustment to account for ethnic facial anthropometric differences.

Recipient Selection Criteria for Facial Transplantation: A Systematic Review.

BACKGROUND: Recipient selection is an important determinant of surgical outcomes in facial transplantation (FT). Appropriately, each FT program develops their own guidelines for recipient selection criteria. Currently, there is no resource to simultaneously assess and identify similarities and differences between these guidelines. Such information could be useful in distinguishing areas of FT that are well understood from those that could benefit from further exploration. METHODS: We performed a systematic review of the scientific literature from inception to June 18, 2021, using Pubmed, Embase, Cochrane Library, and Scopus to identify articles pertaining to recipient selection criteria. Clinical trials were identified through the Clinicaltrials.gov registry. United States and international program websites were reviewed for patient-facing information. RESULTS: Our systematic review yielded 90 suitable articles, 8 clinical trials, and 7 program websites containing the recipient selection criteria of 24 different FT programs. The most reported on recipient criteria were age, positive human immunodeficiency viral status (HIV+), positive hepatitis C viral status, psychosocial stability, and medical compliance. Other criteria were rarely addressed, such as blindness and recipient immune status. CONCLUSIONS: Guidelines among different face transplant programs are changing over time. We found consensus on certain recipient selection criteria, but the majority remain program or surgeon dependent, emphasizing that FT is still an evolving procedure. Although most programs reported on their recipient selection criteria, the rationale was often missing. Further discussion about recipient selection criteria and the reasoning behind employing or changing them will help advance the field.

Quantification of Facial Allograft Edema During Acute Rejection: A Software-Based 3-Dimensional Analysis.

BACKGROUND: Acute rejection (AR) is a common complication in facial transplant (FT) patients associated with allograft edema and erythema. Our study aims to demonstrate the feasibility of using software-based 3-dimensional (3D) facial analysis to quantify edema as it resolves during/after AR treatment in an FT patient. METHODS: Our patient is a 23-year-old man who underwent a face and bilateral hand allotransplant in August 2020. The Vectra H1 (Canfield, Fairfield, NJ) portable scanner was used to capture 3D facial images at 8 time points between postoperative day (POD) 392 and 539. The images were analyzed with the Vectra Software using a rejection-free image (POD 539) as a control. RESULTS: Edema increased in the periorbital, lower third, and submandibular regions before AR treatment (POD 392-415). At POD 448, total facial edema was reduced to near baseline values in response to plasmapheresis and thymoglobulin (+156.94 to +28.2 mL). The fastest and most notable response to treatment was seen in the periorbital region, while some edema remained in the submandibular (+19.79 mL) and right lower third (+8.65 mL) regions. On POD 465, after the initial improvement, the edema increased but was resolved with steroid use. Facial edema did not correlate with the histopathological evaluation in our patient. CONCLUSIONS: We demonstrated the feasibility of analyzing 3D facial images to quantify edema during/after AR treatment in an FT patient. Our analysis detected edema changes consistent with AR followed by an improvement after treatment. This technology shows promise for noninvasive monitoring of FT patients.

Techniques and Trends of Facial Feminization Surgery: A Systematic Review and Representative Case Report.

BACKGROUND: Facial feminization surgery is composed of a variety of craniomaxillofacial surgical procedures that are increasingly sought after by male-to-female transgender patients and by those seeking feminization of the face. Facial feminization surgery can play a prominent role in alleviating gender dysphoria. In consideration of an observed increase in gender-affirming procedures performed in recent years, a broad knowledge base in the techniques, outcomes, and challenges of facial feminization surgery should be established by surgeons offering these procedures. Our review was designed to critically appraise the current literature and inform future advancements in gender-affirming surgical practice. In addition, we detail a representative case to illustrate the senior author's approach to full facial feminization. METHODS: A comprehensive literature search of the PubMed, EMBASE, and Cochrane databases was conducted for studies published through June 2020 using following the search terms: "Face" OR "facial" OR "craniofacial" AND "Feminization" OR "Feminization Surgery" OR "Gender Reassignment" OR "Gender Affirming Surgery" OR "Gender Confirmation Surgery." Data on procedures, outcomes, patient age, follow-up time, complications, and patient satisfaction were collected. The data were categorized by facial thirds and then further stratified by facial feature. RESULTS: Our search yielded 388 articles. Thirty articles fit our inclusion criteria, and of these, 23 articles were included in the review. We extracted primary data pertaining to 3554 patients with an age range of 18 to 73 who underwent 8506 total procedures. Most of the procedures addressed the upper facial third (hairline, forehead, and brow), comprising 49.1% of total procedures performed. Further categorization by facial feature revealed that the most commonly addressed feature was the forehead (34.6% of procedures), followed by the nose (12.8%) and the chin (12.2%). In studies that used quantitative measures to gauge patient-reported outcomes, satisfaction was high. CONCLUSIONS: Facial feminization surgery seems to be safe, whether it is conducted in a single stage or as a staged procedure. Patients report high satisfaction and better gender congruency after facial feminization procedures. Further research is needed to establish best surgical practice and gauge patient satisfaction beyond the length of average follow-up and determine the frequency with which adjunctive procedures are sought out.

Single Versus Double Venous Anastomosis Microvascular Free Flaps for Head and Neck Reconstruction.

ABSTRACT: Venous congestion accounts for most microvascular free tissue flaps failures. Given the lack of consensus on the use of single versus dual venous outflow, the authors present our institutional experience with 1 versus 2 vein anastomoses in microvascular free flap for head and neck reconstruction. A retrospective chart review was performed on all patients undergoing free flaps for head and neck reconstruction at our institution between 2008 and 2020. The authors included patients who underwent anterolateral thigh, radial forearm free flap, or fibula free flaps. The authors classified patients based on the number of venous anastomoses used and compared complication rates. A total of 279 patients with a mean age of 55.11 years (standard deviation 19.31) were included. One hundred sixty-eight patients (60.2%) underwent fibula free flaps, 59 (21.1%) anterolateral thigh, and 52 (18.6%) radial forearm free flap. The majority of patients were American Society of Anesthesiologists classification III or higher (N = 158, 56.6%) and had history of radiation (N = 156, 55.9%). Most flaps were performed using a single venous anastomosis (83.8%). Univariate analysis of postoperative outcomes demonstrated no significant differences in overall complications (P = 0.788), flap failure (P = 1.0), return to the Operating Room (OR) (P = 1.0), hematoma (P = 0.225), length of hospital stay (P = 0.725), or venous congestion (P = 0.479). In our cohort, the rate of venous congestion was not statistically different between flaps with 1 and 2 venous anastomoses. Decision to perform a second venous anastomoses should be guided by anatomical location, vessel lie, flap size, and intraoperative visual assessment.

Consideration of Human Immunodeficiency Status in Patients Seeking Facial Feminization Surgery.

ABSTRACT: Facial feminization surgery (FFS) with its proven safety and efficacy has become a mainstay surgical approach for those desiring gender-specific perceived feminine facial aesthetics. To date, specific characteristics of patients seeking FFS have been limited, with no studies investigating the role of the Human Immunodeficiency Virus (HIV) on FFS outcomes. The potential clinical implications of HIV and more specifically HIV-associated lipodystrophy, which can cause facial lipoatrophy, require further investigation. Given the importance of midface projection in feminizing the face, the authors aimed to investigate any associations HIV or Highly Active Antiretroviral Therapy may have on outcomes, including clinical consequences of facial lipoatrophy. The authors performed a retrospective chart review of all patients with a diagnosis of gender dysphoria referred to the senior author (EDR) for FFS between 2017 and 2020. Patients were grouped based on HIV status and demographics, history, and outcomes were assessed. Seventy-seven patients were included, with 28 patients (36.4%) having a diagnosis of HIV. A total of 25 (32.5%) and 23 (29.9%) patients underwent malar fat grafting and cheek implants, respectively. No significant difference was found between HIV-positive and HIV-negative patients when looking at the use of malar fat grafting, cheek implants, age, or complication rates. To the best of our knowledge, this study presents the largest cohort of HIV status assessment of FFS patients to date. Future studies, particularly on the long-term outcomes, are warranted, as is continued information sharing among providers and centers performing FFS, in order to continue advancing the literature and subsequently patient care.

Current Trends in Facial Feminization Surgery: An Assessment of Safety and Style.

BACKGROUND: Facial feminization surgery (FFS) plays an instrumental role in the process of gender affirmation. These procedures are becoming increasingly appreciated for their ability to improve patient satisfaction and gender identity in a way that alleviates gender dysphoria and improves the quality of life. Despite the recent surge in popularity across the US, the current literature lacks evidence on the safety profile of combined facial feminization procedures. Our goal was to determine the safety profile of facial feminization procedures registered on a national surgical database. METHODS: Patients with a primary diagnosis of gender dysphoria undergoing facial surgical procedures were identified from the National Surgical Quality Improvement Program database between the years 2013 and 2018. Demographic characteristics along with 30-day postoperative complications were recorded. Logistic regression models adjusted for confounders were used to determine the independent predictors of postoperative complications. RESULTS: A cohort of 77 patients who underwent a total of 220 procedures was identified. The number of patients undergoing surgery per year increased from three (3.9%) in 2013 to 41 (53.2%) in 2018, a 13.6-fold increase. The most commonly performed procedure was forehead contouring/frontal sinus setback, performed on 52 patients (67.5%), followed by orbital contouring (n = 37, 48%), rhinoplasty (n = 34, 44%), mandibuloplasty (n = 34, 44%), chondrolaryngoplasty (n = 27, 35.1%), genioplasty (n = 11, 14%), brow lift (n = 9, 11.7%), cheek augmentation (n = 9, 11.7%), and lip lift (n = 7, 9.1%). The number of patients who underwent 5 or more procedures in a single anesthetic event was 41 (53.2%). The complication rate was 3.9%. Univariate analysis suggested an association between older age and postoperative morbidity (P  < 0.02). However, this was not found to be an independent predictor on multivariate analysis adjusted for confounders (P < 0.083). Additionally, an increase in operative time and the number of procedures performed during a single anesthetic were not independent predictors of 30-day postoperative complications (P < 0.317 and P  < 0.19, respectively). CONCLUSIONS: FFS can be safely performed and has a low risk of postoperative morbidity. The number of patients seeking FFS surgery has risen exponentially, with the highest demand seen for the reconstruction of the upper facial third. These findings should guide expectations for patients seeking FFS, as well as for plastic surgeons looking to perform multiple procedures per anesthetic event.

Comparative Outcomes of Partial and Full Facial Feminization Surgery: A Retrospective Cohort Study.

BACKGROUND: The demand for facial feminization surgery (FFS) amongst transgender women is on the rise, and requests for a single-stage full FFS (F-FFS) are becoming more frequent. The specific aim of this article is to present our institutional experience with both partial-FFS (P-FFS) and F-FFS with a specific emphasis on safety of each approach. METHODS: We examined the electronic medical record of all patients with the diagnosis of gender dysphoria that were referred to the senior author for FFS consultation at our institution, between June 2017 and October 2020. Patients were sub-grouped into those who underwent F-FFS (upper, middle, and lower facial thirds in a single anesthetic event) and those who underwent P-FFS. Univariate analysis was used to assess for difference in postoperative complications. RESULTS: We identified 77 patients who underwent 382 total procedures. The mean follow-up time was 7.5 months (Sd = 7.3) (interquartile range 1.75-12.0 months). Fifty-one (71.4%) patients underwent F-FFS and 21 (28.6%) patients underwent P-FFS. Compared to P-FFS, F-FFS was not associated with an increase in postoperative complication (1 out of 21 [4.8%] versus 4 out of 51 [7.8%]) ( P < 0.556). When comparing characteristics of patients with postoperative complications to patients with no postoperative complications, the average body mass index was significantly higher (30.9 versus 25.4, respectively). ( P < 0.029). CONCLUSIONS: Full-FFS is a set of procedures that has gained increased popularity among male-to-female transgender patients. Our results support the understanding that F-FFS is a safe and reliable approach, which may be preferable to patients and providers alike.

Immunologic Outcomes in Cross-Sex Solid Organ Transplants: A Systematic Review and Meta-Analysis to Inform Vascularized Composite Allotransplantation.

BACKGROUND: Of nearly 90 hand and 50 face transplant recipients, only five have received a cross-sex vascularized composite allotransplantation (CS-VCA). CS-VCA has the potential to expand the donor pool and has been proven anatomically feasible and ethically acceptable in previous studies. However, there is a lack of immunologic data. This study evaluated the immunologic feasibility of CS-VCA through analysis of the solid organ transplant literature, given the paucity of CS-VCA data. The authors hypothesize that rates of acute rejection (AR) and graft survival (GS) in CS versus same-sex (SS) solid organ transplantation are similar. METHODS: A systematic review and meta-analysis were performed. Studies comparing GS or AR episodes in CS and SS adult kidney (KT) and liver transplant (LT) populations were included. Odds ratios were calculated for overall GS and AR for all SS and CS transplant combinations [male-to-female (MTF), female-to-male, and overall]. RESULTS: A total of 693 articles were initially identified with 25 included in the meta-analysis. No significant difference in GS was noted between SS-KT versus CS-KT [OR, 1.04 (95% CI, 1.00 to 1.07); P = 0.07), SS-KT versus MTF-KT [OR, 0.97 (95% CI, 0.90 to 1.04); P = 0.41), and SS-LT versus MTF-LT [OR, 0.95 (95% CI, 0.91 to 1.00); P = 0.05). No significant difference in AR was noted between SS-KT versus MTF-KT [OR, 0.99 (95% CI, 0.96 to 1.02); P = 0.57), SS-LT versus CS-LT [OR, 0.78 (95% CI, 0.53 to 1.16); P = 0.22], or SS-LT versus female-to-male LT [OR, 1.03 (95% CI, 0.95 to 1.12); P = 0.47]. For the remaining pairings, GS was significantly increased and AR was significantly decreased in the SS transplants. CONCLUSIONS: Published data suggest immunologic feasibility of CS-KT and CS-LT with the potential for generalization to the VCA population. CLINICAL RELEVANCE STATEMENT: In theory, CS-VCA could expand the potential donor pool, ultimately leading to decreased wait times for recipients and improve the likelihood of establishing a immunologically favorable donor-recipient match.

Gender-affirming hysterectomy in the United States: A comparative outcomes analysis and potential implications for uterine transplantation.

PURPOSE: Hysterectomy is a gynecological procedure sometimes performed as part of the gender-affirming process for transgender and gender-expansive patients assigned female at birth. Our goal was to compare surgical outcomes between patients undergoing gender-affirming hysterectomy and patients undergoing hysterectomy for benign menstrual disorders. We then explored the implications of gender-affirming hysterectomy for uterine transplantation. METHODS: We performed a retrospective cohort study using data from the American College of Surgeons National Surgical Quality Improvement Program database from 2009 through 2018. We identified patients undergoing hysterectomy in the United States based on Current Procedural Terminology code. We used the International Classification of Diseases 9 or 10 codes to identify patients with benign menstrual disorders (non-gender-affirming group) and gender dysphoria (gender-affirming group). We compared patient characteristics and surgical complications. RESULTS: Of the 40,742 patients that met inclusion criteria, 526 (1.3%) patients were individuals with gender dysphoria. Compared to patients who underwent hysterectomy for benign menstrual disorders, gender-affirming patients were younger, were healthier, had a lower prevalence of diabetes, and were more likely to undergo surgery in the outpatient setting, with shorter time to discharge. Complication rates were similar between groups. Logistic regression controlling for the American Society of Anesthesiology classification determined the difference of return to the operating room was not statistically significant (OR 1.082; 95% CI, 0.56-2.10; p = 0.816). CONCLUSION: Gender-affirming hysterectomy has a safety profile similar to hysterectomy performed for benign menstrual disorders. Researchers should further explore the possibility of uterus donation among these patients as they may be suitable candidates.

Recognizing Racial Disparities in Postoperative Outcomes of Gender Affirming Surgery.

Purpose: Given the increasing frequency with which gender affirming surgery (GAS) is performed, understanding risk factors for poor outcomes is imperative. Recent investigations highlight inferior health outcomes experienced by Black transgender and gender expansive (TGE) individuals. Herein, we evaluate the relationship between race and postoperative outcomes in TGE patients undergoing GAS, utilizing the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). Methods: We conducted a retrospective review of ACS NSQIP from 2010 to 2018. Patients with a primary diagnosis of gender dysphoria undergoing GAS were identified and grouped by race. Patient characteristics and 30-day postoperative outcomes were recorded. Univariate analysis was used to compare patient characteristics and postoperative outcomes across groups. Multivariate logistic regression was used to determine independent predictors of complications. Results: We included 2308 patients (1780 White, 419 Black, 109 Asian). Gender, body mass index, smoking status, and type of surgery performed differed significantly between groups (p < 0.001). Univariate analysis revealed significant differences in 30-day readmission and organ space surgical site infection (SSI) across groups (p = 0.03). Multivariate logistic regression, adjusted for confounders, revealed that Black patients had higher odds of reoperation (odds ratio [OR] 1.82, p = 0.047), 30-day readmission (OR 2.46, p = 0.003), and organ space SSI (OR 4.65, p = 0.024) than White patients. Conclusion: We found that race was an independent predictor of important short-term postoperative outcomes in GAS. Inclusive clinical research, effective engagement with the TGE community, and surgery-specific enhanced recovery after surgery protocols may help address disparities, but we must acknowledge race as a social determinant of health.

Gender Affirmation Surgery on the Rise: Analysis of Trends and Outcomes.

Purpose: Gender-affirming surgery (GAS) has become an important component of the treatment of gender dysphoria. Although the frequency of these procedures is on the rise, a complete safety profile has yet to be established. The goal of our study is to analyze the trends and outcomes of these surgical procedures. Methods: All patients with a primary diagnosis of gender dysphoria undergoing GAS were identified from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database between the years 2009 and 2018. Patient demographics and 30-day postoperative outcomes were recorded. We performed a multivariate logistic regression for postoperative complications, controlling for several confounding variables. Results: We identified 2956 patients, of which 1767 (59.78%) were transgender men and 1189 (40.22%) were transgender women. The number of patients undergoing GAS per year increased from 7 in 2010 to 1069 in 2018, a 152-fold increase. For patients undergoing top surgery, Black race (odds ratio [OR] = 2.255, 95% confidence interval [CI] 1.189-4.277, p = 0.013) and diabetes (OR = 4.156, 95% CI 1.571-10.999, p = 0.004) were independent predictors of 30-day postoperative complications. For patients undergoing bottom surgery, total operative time in minutes (OR = 1.005, 95% CI 1.003-1.007, p = 0.001) was an independent predictor of 30-day postoperative complications. Conclusion: The demand for GAS has increased exponentially since 2014. While postoperative complication rates are acceptable, Black race was shown to be an independent predictor of postoperative morbidity in patients undergoing top surgery, a finding that calls for further investigation of racial disparities among transgender patients.

Patient-centred outcomes and dental implant placement in computer-aided free flap mandibular reconstruction: a systematic review and meta-analysis.

Computerised surgical planning (CSP) and computer-aided design and manufacturing (CAD/CAM) have been demonstrated to increase surgical accuracy and reduce operative time in free flap mandibular reconstruction, but evidence is lacking as to their impact on patient-centred outcomes. Implant-supported dental prostheses, however, have been associated with improved quality of life outcomes following free flap mandibular reconstruction. We aim to review reported patient-centred outcomes in mandibular reconstruction with CSP and CAD/CAM and determine whether use of these technologies is associated with higher rates of dental implant placement following free flap mandibular reconstruction. On December 20, 2020, a systematic review and meta-analysis were conducted according to PRISMA guidelines for studies reporting quality of life, functional outcomes, and rates of dental implant placement in computer-aided free flap mandibular reconstruction. A random-effects meta-analysis was performed to compare dental implant placement rates between surgeries using CSP and those using conventional freehand techniques. A total of 767 articles were screened. Nine articles reporting patient-centred outcomes and 16 articles reporting dental implant outcomes were reviewed. Of those reporting dental implant outcomes, five articles, representing a total of 302 cases, were included in the meta-analysis. Use of CSP was associated with a significant increase in the likelihood of dental implant placement, with an odds ratio of 2.70 (95% CI 1.52 to 4.79, p = 0.0007). Standardised reporting methods and controlled studies are needed to further investigate the impact of CSP and CAD/CAM technologies on functional outcomes and patient-reported quality of life in free flap mandibular reconstruction. Use of CSP and CAD/CAM technologies is associated with higher rates of dental implant placement in patients undergoing free flap mandibular reconstruction when compared to conventional freehand techniques.

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.

Double-Barrel Versus Single-Barrel Fibula Flaps for Mandibular Reconstruction: Safety and Outcomes.

OBJECTIVES/HYPOTHESIS: Fibula flaps are routinely used for osseous reconstruction of head and neck defects. However, single-barrel fibula flaps may result in a height discrepancy between native mandible and grafted bone, limiting outcomes from both an aesthetic and dental standpoint. The double-barrel fibula flap aims to resolve this. We present our institution's outcomes comparing both flap designs. STUDY DESIGN: Retrospective cohort study. METHODS: We conducted a retrospective review of all patients undergoing free fibula flap mandibular reconstruction at our institution between October 2008 and October 2020. Patients were grouped based on whether they underwent single-barrel or double-barrel reconstruction. Postoperative outcomes data were collected and compared between groups. Differences in categorical and continuous variables were assessed using a Chi-square test or Student's t-test, respectively. RESULTS: Out of 168 patients, 126 underwent single-barrel and 42 underwent double-barrel reconstruction. There was no significant difference in postoperative morbidity between approaches, including total complications (P = .37), flap-related complications (P = .62), takeback to the operating room (P = .75), flap salvage (P = .66), flap failure (P = .45), and mortality (P = .19). In addition, there was no significant difference in operative time (P = .86) or duration of hospital stay (P = .17). After adjusting for confounders, primary dental implantation was significantly higher in the double-barrel group (odds ratio, 3.02; 95% confidence interval, 1.2-7.6; P = .019). CONCLUSION: Double-barrel fibula flap mandibular reconstruction can be performed safely without increased postoperative morbidity or duration of hospital stay relative to single-barrel reconstruction. Moreover, the double-barrel approach is associated with higher odds of primary dental implantation and may warrant further consideration as part of an expanded toolkit for achieving early dental rehabilitation.
