Association of High Body Mass Index With Postoperative Complications After Chest Masculinization Surgery.

PURPOSE: Body mass index (BMI) requirements for transgender and nonbinary patients undergoing chest masculinization surgery (CMS) are not standardized and based on small sample sizes. This is the largest and first national retrospective study to determine the association between BMI and postoperative complications. METHODS: The National Surgical Quality Improvement Program 2012-2020 was queried for CMS patients. The primary outcome was incidence of at least one complication within 30 days. Secondary outcomes were incidence of major and minor complications. Body mass index (in kilograms per square meter) was categorized as category 0 (<30), 1 (30-34.9), 2 (35-39.9), 3 (40-44.9), 4 (45-49.9), and 5 (≥50). Logistic regression was used to evaluate the association between BMI and outcomes. RESULTS: Of 2317 patients, median BMI was 27.4 kg/m 2 (interquartile range, 23.4-32.2 kg/m 2 ). Body mass index range was 15.6 to 64.9 kg/m 2 . While increasing BMI was significantly associated with greater odds of at least one complication, no patients experienced severe morbidity, regardless of BMI. Patients with BMI ≥50 kg/m 2 had an adjusted odds ratio [aOR, 95% confidence interval (CI)] of 3.63 (1.02-12.85) and 36.62 (2.96->100) greater odds of at least one complication and urinary tract infection compared with nonobese patients, respectively. Patients with BMI ≥35 kg/m 2 had an adjusted odds ratio (95% CI) of 5.06 (1.5-17.04) and 5.13 (1.89-13.95) greater odds of readmission and surgical site infection compared with nonobese patients, respectively. CONCLUSIONS: Chest masculinization surgery in higher BMI patients is associated with greater odds of unplanned readmission. Given the low risk for severe complications in higher BMI individuals, we recommend re-evaluation of BMI cutoffs for CMS patients.

The Effect of Obesity on Vaginoplasty Outcomes.

BACKGROUND: Some surgeons use body mass index criteria within the patient selection processes before vaginoplasty, thereby limiting access to select obese patients. We sought to better characterize the effect of obesity on postoperative outcomes across multiple vaginoplasty techniques. METHODS: A single-center retrospective review of all transfeminine patients undergoing primary vaginoplasty procedures from December 2018 to July 2022 was conducted. Patients were stratified into cohorts according to the World Health Organization Obesity Class criteria. Data regarding demographics, comorbidities, operative details, postoperative complications, and all-cause revision were collected. RESULTS: A total of 237 patients met the inclusion criteria. Average follow-up duration was 9.1 ± 4.7 months. Multivariate regression revealed that patients with class I and class II/III obesity were associated with higher odds of developing vaginal stenosis (class I: odds ratio [OR], 7.1 [ P = 0.003]; class II/III: OR, 3.4 [ P = 0.018]) and all-cause revision (class I: OR, 3.7 [ P = 0.021]; class II/III: OR, 4.8 [ P = 0.027]). Undergoing either robotic peritoneal or robotic intestinal vaginoplasty was associated with lower odds of delayed wound healing (peritoneal: OR, 0.2 [ P < 0.001]; intestinal: OR, 0.2 [ P = 0.011]). Lastly, adherence to dilation regimen was negatively associated with development of vaginal stenosis (OR, 0.04; P < 0.001). CONCLUSIONS: Patients with obesity may be at a higher risk of developing vaginal stenosis after vaginoplasty, which may ultimately necessitate operative revision. Although patients with obesity may remain surgical candidates, proper preoperative counseling and adherence to postoperative vaginal dilation regimens are critical to optimizing outcomes.

The robotic-assisted free jejunal flap for neovaginal canal creation in gender-affirming vaginoplasties.

INTRODUCTION: One of the biggest challenges with gender-affirming vaginoplasty was the creation of a long-lasting, durable, patent, and self-lubricating neovaginal canal that allowed for spontaneous, pain-free sexual intercourse. The jejunum was a durable, physiologic, and intestinal option to create the neovaginal canal that minimizes the adverse effects of skin graft, peritoneal, and colonic vaginoplasties. Free jejunal vaginoplasties had been performed in cis females for congenital genitourinary anomalies like Mullerian agenesis or after gynecologic-oncologic surgery but had yet to be reported for gender-affirming vaginoplasties. The purpose of this report was to present a technique for a physiologic, intestinal, gender-affirming vaginoplasty without the disadvantages of colonic vaginoplasties. PATIENTS AND METHODS: This report presented six patients, all natal males who identified as female, undergoing robotic-assisted free jejunal flap gender-affirming vaginoplasty. Mean age was 35.8 years (range: 21-66). Mean body mass index was 33.2 kg/m2 (range: 28.0-41.0). The proximal aspect of the neovaginal canal was created intra-abdominally by elevating peritoneal flaps from the posterior bladder wall to be reflected downward into the external neovaginal canal. The jejunal flap was harvested. The greater saphenous vein was harvested to create an arteriovenous loop between the flap vessels and the recipient femoral artery in an end-to-side fashion and a branch of the femoral vein. The jejunal flap was passed intra-abdominally through the groin incision and then trans-peritoneally into the neovaginal canal. The jejunal segment was inset to the proximal peritoneal flaps and the distal inverted penoscrotal skin of the neovaginal introitus. RESULTS: Mean length of the harvest jejunal segment was 19.2 cm (range: 15-20). Mean time to ambulation, foley removal, and first vaginal dilation were 3.3 (range: 3-4), 4.0 (range: 3-5), and 4.5 days (range: 4-6), respectively. By a mean follow-up duration of 8.0 months (range: 1-14), mean vaginal depth and diameter were 7.0 and 1.3 cm (range: 1.0-1.5), respectively. Two (33.3%) patients experienced postoperative complications, including groin hematoma (n = 1, 16.7%) and reoperation for correction of dehiscence of the jejunal flap to the vaginal introitus (n = 1, 16.7%). CONCLUSION: Gender-affirming surgeons should consider a free vascularized segment of jejunum as an option to line the neovaginal canal in the correct patients.

Outcomes in chest feminization patients with a history of illicit hormone use and silicone injections.

Transfeminine patients facing barriers to gender confirming surgery sometimes pursue illicit feminization procedures such as "street" hormones and silicone injections. These procedures often yield complications and disfigurement, making surgeons and insurance companies wary of secondary breast reconstruction. This clinical series assesses illicit treatment among our transfeminine breast surgery patients and describes the presentation, surgical approaches, and outcomes of each patient. A retrospective review of transfeminine patients who underwent chest feminization surgery with a single provider between March 2018 and March 2020 identified patients with a history of illicit hormones or silicone injections. Demographics, comorbidities, preoperative diagnoses and symptoms, surgical details, and postoperative outcomes were collected. Patients were contacted for a follow-up survey concerning outcomes and satisfaction. Of the 41 transfeminine patients reviewed, eight (19.5%) had previous illicit treatment. Seven (17.1%) used non-prescribed hormones, and three (7.3%) received silicone breast injections. Two patients presented with symptoms from silicone injections; the remaining were asymptomatic. Six patients underwent subglandular breast augmentation, one had a reduction mammoplasty, and one underwent an implant exchange. Only one patient had postoperative complications that healed without surgical intervention. This series emphasizes the need to assess the prevalence of silicone injections and illicit hormone use among transgender chest feminization patients. The use of these substances was relatively high in our population compared to national averages; however, there is a low risk of postoperative complications. Providers may perform breast surgery in patients with a history of illicit augmentation practices after careful evaluation and surgical planning.

Delivery of nipple-sparing mastectomy within a single healthcare system: The impact of provider preferences.

Nipple-sparing mastectomy (NSM) offers superior esthetic outcomes without sacrificing oncologic safety for select patients requiring mastectomy. While disparities in oncologic care are well established, no study to date has investigated equitable delivery of the various mastectomy types. The objective of this study is to examine multilevel factors related to the distribution of NSM. Patients undergoing mastectomy between 2014 and 2018 across eight hospitals in a single healthcare system were retrospectively reviewed. Patients were categorized by mastectomy type-NSM or other mastectomy (OM). Patient information such as age, race, comorbidities, and median income by ZIP code was collected. Disease characteristics, such as mastectomy weight, breast cancer stage, and treatment history, were identified. Provider and system-level variables, such as specific provider, hospital of operation, and insurance status, were determined. Bivariate analysis was used to identify variables for inclusion in a backward multivariable model. A cohort of 1202 mastectomy patients was identified, with 388 receiving NSM. The average age was 55.8 years (NSM: 48.8, OM: 59.1, P < .001). 39.8% of white patients (n = 242) and 20.0% of African American patients (n = 88) received NSM (P < .001). Average mastectomy weight was 384.3 (SD 195.7) in the NSM group, compared to 839.4 (SD 521.1) in the OM group (P < .001). 41.4% (n = 359) of patients treated at academic centers, and 6.9% (n = 21) of patients treated at community centers received NSM (P < .001). In the multivariate model, the factor with the largest impact on NSM was specific provider. Odds of NSM decreased by 76%-88% for certain surgeons, while odds increased by 63 times for one surgeon. This study utilizes a large multi-institutional database to highlight disparities in NSM delivery. Expectedly, younger, relatively healthy patients, with smaller breast size were more likely to undergo NSM, in accordance with surgical guidelines. However, when all other factors were controlled, provider preferences played the most significant role in NSM delivery rates. These findings demonstrate the need for practice reexamination to ensure equitable access to NSM.

Does surgeon handedness or experience predict immediate complications after mastectomy? A critical examination of outcomes in a single health system.

Surgeons often seek to perfect their technical dexterity, and hand dominance of the surgeon is an important factor given the constraints of operative field laterality. However, experience often dictates how surgeons are able to compensate. While surgeons have experienced preference for the ipsilateral breast, the impact of surgeon handedness, experience, and volume has not been directly examined in a single study. A retrospective chart review of five breast surgeons (2 LHD) at a single institution identified 365 mastectomy patients, totaling 594 breasts, between January 2015 and June 2018. The breasts were identified as ipsilateral or contralateral based on the surgeons' handedness. Surgeons were grouped based on length of surgical experience, three with ≥15 years and two with <15 years. Surgeons with greater experience were the highest volume surgeons in this series. Data included patient demographics, breast and oncologic history, surgical techniques, and surgical outcomes including complications. A total of 270 nonprophylactic and 324 prophylactic mastectomies were identified, of which 529 were performed by surgeons with greater than 15 years of experience and 65 by surgeons with less than 15 years. The overall complication rate was 33.5% (n = 199), of which 18.0% (n = 107) were on the ipsilateral breast and 15.5% (n = 92) were on the contralateral breast. 9.1% of complications required re-operation (n = 54). The odds of any complication on the ipsilateral breast were 2.9 times higher than complications on the contralateral breast when looking exclusively at surgeons with <15 years of experience (P = .0353, OR = 2.92, 1.06-8.03). Surgeons with <15 years of experience have a 2.71 (P = .05, OR 2.71, 1.361-5.373) increase in any ischemic complication and a 16 times (P < .0001, OR = 16.01, 5.038-50.933) increase in major operative ischemic complications. Our study finds that surgeons with less than 15 years of surgical experience have a 2.9 times higher rate of overall complication when operating on the ipsilateral breast. However, years of experience and surgeon volume have a much greater impact on any and ischemic complications after mastectomy.

Incidence of Complications in Delayed Abdominal-Based Flap Breast Reconstruction Using a Drainless Recipient Site: A Case Series.

BACKGROUND: Seroma is a common complication after breast surgery such as mastectomy and immediate reconstruction. However, there is a lack of evidence for the utility of drains in the recipient site in delayed autologous breast reconstruction. We reviewed our experience with delayed abdominal-based flap breast reconstruction with a drainless recipient site. METHODS: A single-surgeon retrospective case review was performed for delayed abdominal-based flap breast reconstruction using drainless recipient sites from May 2018 to June 2019. Primary outcomes were recipient-site complications. RESULTS: Thirty-one delayed abdominal-based flap breast reconstructions that did not use drains in the recipient site were identified in 22 patients. Mean age was 52.8 years (SD, 9.7 years). Mean body mass index was 30.1 kg/m (interquartile range [IQR], 28.2-35.0 kg/m). Common comorbidities were obesity (45.4%), prior tobacco use (31.8%), and diabetes (10.0%). Median time to abdominal-based flap reconstruction was 27.5 months (IQR, 9.9-105.2 months). There were 22 muscle-sparing transverse rectus abdominis musculocutaneous flaps and 9 deep inferior epigastric artery perforator flaps performed. Ten patients (45.4%) underwent bilateral reconstruction. Mean operative time was 302 minutes (SD, 85 minutes). Flap take back occurred in 1 case (3.2%). Mean length of stay was 4 days (SD, 0.8 days). Recipient-site complications were healing complications (32.3%), seroma (3.2%), hematoma (3.2%), and fat necrosis (19.4%). Median follow-up was 4.2 months (IQR, 2.5-11.5). CONCLUSIONS: In this case series, our data indicate that delayed autologous reconstruction without drain placement at the recipient site has been proven to be safe and successful and did not increase the rate of seroma or other complications. Adopting a drainless approach may also improve patient comfort and satisfaction.

The "String of Pearls" technique for increased surface area and lymphedematous fluid drainage in right gastroepiploic-vascularized lymph node transfer: A report of two cases.

We present our "String of Pearls" technique for upper and lower extremity lymphedema based off the right gastroepiploic artery. The entire laprascopically harvested omentum is placed through a longitudinal incision at the lymphedematous area, and anastomosed proximally, with additional distal venous outflow. This approach preserves the native lymphaticovenous architecture, distributes free lymphatic tissue along the axis of the extremity, and allows for scar release. The additional vein serves to restore bidirectional physiologic drainage inherent in the omentum and providing further lymphaticovenous drainage. We present two cases of upper and lower extremity lymphedema as a result of malignancy treated using this method. The first case was a result of breast cancer in a 55-year-old female with orthotopically placed omentum, and the second case a result of malignant nodular fasciitis in the distal lower extremity in a 56-year-old female with distally placed omentum. No complications occurred. At 3 months follow up, there is a 25% and 28% reduction in lower and upper extremity volume, respectively, with no recurrent cellulitis episodes. The safety and feasibility of placement of the entire omentum longitudinally with additional venous anastomosis are apparent. However, long-term studies are required.

Outcomes and Cost Analysis in High-Risk Patients Undergoing Simultaneous Free Flap Breast Reconstruction and Gynecologic Procedures.

BACKGROUND: For patients with BRCA mutations, a simultaneous procedure that combines risk-reducing operation of the ovaries with mastectomy and breast reconstruction is an attractive option. The purpose of this study was to assess the outcomes and associated cost of performing simultaneous mastectomy, free flap breast reconstruction (FFR), and gynecologic procedure. METHODS: A retrospective chart review was performed on patients who underwent bilateral FFR from 2005 to 2012. Four hundred twenty-two patients were identified who underwent bilateral breast reconstruction without a simultaneous gynecologic procedure. Forty-two patients were identified who underwent simultaneous FFR and gynecologic procedure. Clinical outcomes, medical and surgical complications, and hospital costs were analyzed and compared between the 2 groups. RESULTS: A total of 928 free flaps were performed on 464 patients. Forty-two patients had a simultaneous gynecologic procedure at the time of breast reconstruction. Twenty-three (54.8%) patients within the study group underwent simultaneous bilateral salpingo oophorectomy (BSO), whereas the other 19 (45.2%) underwent both total abdominal hysterectomy and BSO. Eighty-four free flaps were performed in this cohort (n = 48 muscle-sparing transverse rectus abdominis myocutaneous, n = 28 deep inferior epigastric perforator, n = 4 superficial inferior epigastric perforator, n = 4 transverse upper gracilis). Mean operative time was 573 minutes. Mean hospitalization was 5.3 days. Postoperatively, 4 patients experienced an anastomotic thrombosis; 2 patients had an arterial thrombosis and 2 patients had a venous thrombosis. There were 2 flap failures, 2 patients with mastectomy skin flap necrosis, 11 patients who developed breast wound healing complications, and 6 patients who developed abdominal wound healing complications. Surgical and medical complication rates did not differ significantly between those who had simultaneous procedures, and those who did not. There was a statistically significant difference in the average total cost when comparing the group of patients receiving prophylactic mastectomy/FFR/total abdominal hysterectomy and/or BSO versus the patients who did not have combined gynecologic procedures at the time of reconstruction ($22,994.52 vs $21,029.23, P = 0.0004). CONCLUSIONS: For the high-risk breast cancer patient, a combined mastectomy, free flap reconstruction, and gynecologic procedure represents an attractive and safe option.

The Clinical Role of Intraoperative Core Temperature in Free Tissue Transfer.

BACKGROUND: Lengthy microvascular procedures carry hypothermia risk, yet limited published data evaluate the overall impact of core temperature on patient and flap morbidity. Although hypothermia may contribute to complications, warming measures are challenged by conflicting reports of intraoperative hypothermia improving anastomotic patency. METHODS: A retrospective review included all free flaps performed by plastic surgeons at an academic medical center from December 2005 to December 2010. Intraoperative core temperatures were measured by esophageal probe, and median values recorded over 5-minute intervals yielded a case mean (Tavg), maximum (Tmax), and nadir (Tmin). Outcomes included flap failure, pedicle thrombosis, recipient site infection and complications associated with patient, and flap morbidity. Analysis used Student t test, Fisher exact test, Probit, and logistic regression. RESULTS: Of 156 consecutive free tissue transfers, the median Tavg, Tmax, and Tmin were 36.5°C, 37.1°C, and 35.8°C, respectively. The flap failure rate was 7.7% (12/156) and pedicle thrombosis occurred in 9 (6%) cases. Core temperatures did not associate with overall flap failure or pedicle thrombosis but recipient site infection occurred in 21 (13%) patients who had significantly lower mean core temperatures (Tavg=36.0°C, P<0.01). Lower Tavg and Tmax significantly predicted recipient site infection (P<0.01 and P<0.05, respectively). Cut-point analysis revealed significant increases in recipient site infection risk at Tavg less than 37.0°C (P=0.026) and Tmin less than or equal to 34.5°C (P=0.020). CONCLUSIONS: Intraoperative hypothermia posed significant risk of flap infection with no benefit to anastomotic patency in free tissue transfer.

Adjuvant radiation therapy increases disease-free survival in stage IB Merkel cell carcinoma.

Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous malignancy. Adjuvant radiation increases survival in advanced stages, but efficacy in stage I disease is unknown. A retrospective review included all patients treated for stage I MCC during a 15-year period at Vanderbilt University Medical Center. Among 42 patients, 26 (62%) had a negative sentinel lymph node biopsy (stage IA) and 16 (38%) had clinically negative lymph nodes (stage IB) at the time of resection. Analysis using Cox regression revealed that higher stage and absence of adjuvant radiation are associated with increased disease recurrence (hazard ratio, 6.29; P=0.003 and hazard ratio, 4.69; P=0.013, respectively). Controlling for stage, radiation therapy significantly increased disease-free survival among patients with stage IB disease (P=0.0026) in a log-rank test comparing Kaplan-Meier curves. These findings support adjuvant radiation therapy in stage IB MCC patients with clinically negative lymph nodes who do not undergo sentinel lymph node biopsy.

Body Contouring as Gender-Affirming Surgery in Transgender Patients: A Systematic Review of the Current Literature.

Background: There is an increasing demand for body contouring and gender-affirming surgeries, and so is the need to compare outcomes between techniques. Gender dysphoria is a discrepancy between gender identity and the sex assigned at birth. One way to address this is to perform procedures to enable patients to look according to their desired gender identity. Gaps in knowledge regarding the best approaches and which surgical techniques yield the most patient satisfaction remain. This article summarizes up-to-date studies, including upper and lower body contouring procedures. Methods: A systematic review was performed using terms related to body contouring in gender-affirming surgery for transgender patients. All articles included surgical and patient-reported outcomes following either chest or lower body contouring procedures. Results: 15 studies, including trans male chest wall contouring, trans female breast augmentation, and lower body contouring, with 1811 patients, fulfilled the inclusion criteria. The double incision (DI) techniques consistently resected more tissue and had better BODY Q scores than non-overweight patients. Bleeding was increased in periareolar, semicircular, and obese patients with DI techniques. Nipple depigmentation and sensation loss were more common with double-incision-free nipple graft techniques (DIFNG). Lower body contouring patients had average implant sizes bigger than 200 mL and reported 2 gluteal implant displacements, 1 exposure, and one rupture. Eight percent of patients who underwent large-volume fat grafting reported dissatisfaction due to fat reabsorption. Conclusions: The debate between the double incision and periareolar techniques continues. Variations of the DIFNG technique continue to be the most common approach; however, nipple depigmentation and loss of sensation are also more common with it. Regarding increased bleeding with periareolar techniques, there is still no evidence that hormonal therapy may be playing a role in it. For lower-body trans female contouring, implants could help with the longevity of contouring results in patients needing large-volume fat grafting. There is an increasing evaluation of gender-affirming body contouring patient-reported outcomes; however, there is still a need for a validated way to report satisfaction scores in lower body contouring. Validated surveys could help identify surgical candidates based on satisfaction patterns, specifically for transgender and non-binary patients.

Factors influencing intraoperative conversion from double- to single-incision mastectomy with free nipple grafts in 352 transgender and non-binary patients.

BACKGROUND: Double-incision mastectomy (DIM) with free nipple grafts (FNG) is a common technique employed in gender-affirming mastectomy (GAM), but is associated with a high scar burden. Intraoperatively, the surgeon may opt for a single-incision mastectomy (SIM) along the inframammary folds (IMF) to optimize aesthetic outcomes. This study sought to identify factors predictive of intraoperative conversion. METHODS: From February 2018 to November 2022, TGNB patients who underwent GAM at a single institution were retrospectively reviewed. Data regarding patient characteristics, perioperative details, postoperative complications, and aesthetic satisfaction were collected. RESULTS: A total of 352 patients were identified. Median age and body mass index (BMI) were 25.0 years (IQR: 9.0) and 28.5 kg/m2 (IQR: 8.5), respectively. Most patients received IMF incisions (n = 331, 94.0%); of whom, 66 (19.9%) underwent intraoperative conversion from DIM to SIM with FNG. Larger breast cup-size (p < 0.001) and a greater degree of ptosis (p = 0.002) preoperatively were significantly associated with intraoperative conversion to SIM. There was no significant association between intraoperative conversion and the ratio of intermammary distance to the width of the chest wall (p = 0.086). Overall complication rates were significantly higher among patients with diabetes mellitus (p = 0.015) and a greater degree of ptosis (p = 0.018). 77.8% (n = 274) of patients were satisfied with their aesthetic outcome. NPWT usage was associated with higher rates of aesthetic satisfaction (83.6% vs. 77.8%; p = 0.005). CONCLUSION: Patients with larger breast cup size and greater degree of ptosis should be counseled preoperatively that they may be at a higher risk of conversion to a singular incision.

Perioperative Patient-Initiated Communication in Gender-Affirming Mastectomy.

Background: Gender-affirming mastectomy (GAM) improves the psychosocial functioning and quality of life of transgender and non-binary (TGNB) individuals. However, the perioperative period is often marked by emotional stress, concerns about surgical outcomes, and physical discomfort. While inpatient procedures provide multiple opportunities to engage with and educate patients, outpatient surgeries, such as GAM, pose a unique challenge as patients are followed for <24 h postoperatively. Given the heightened emotional and psychological distress related to gender dysphoria TGNB individuals often experience, addressing these gaps can significantly improve outcomes. This study aims to characterize patient and surgical characteristics associated with patient-initiated communication (PIC) frequency in this population. Methods: A single-center retrospective review of TGNB patients undergoing GAM from February 2018 to November 2022 was conducted. Demographics, surgical characteristics, and frequency of and reasons for perioperative PIC (30 days before and after surgery) were recorded. The primary outcome was the incidence of perioperative PIC. The secondary outcomes included (1) the rationale for PIC and (2) patient and surgical characteristics associated with PIC. Results: A total of 352 patients were included. Of these, 285 (74.6%) initiated communication in the perioperative period, totaling 659 PICs. The median age was 25.0 (interquartile range [IQR]: 9.0) years. The median body mass index (BMI) was 28.5 (IQR: 8.5) kg/m2. The mean number of PICs was 0.7 ± 1.3 preoperatively and 1.3 ± 1.7 postoperatively (p < 0.001). The most frequent preoperative PIC subjects were administrative issues (AI; n = 66, 30.7%), preoperative requirements (n = 43, 20.0%), and cost and insurance (n = 33, 15.0%). The most frequent postoperative PIC subjects were wound care (n = 77, 17.3%), AI (n = 70, 15.0%), activity restrictions (n = 60, 13.5%), drainage (n = 56, 12.6%), and swelling (n = 37, 8.3%). Collectively, older patients (ß = 0.234, p = 0.001), those with a history of major depressive disorder or generalized anxiety disorder (2.4 ± 3.0 vs. 1.7 ± 1.9; p = 0.019), and those without postoperative drains (n = 16/17, 94.1% vs. n = 236/334, 70.7%; p = 0.025) engaged in higher levels of PIC. There were no significant associations between other patient characteristics, perioperative details, or complications and PIC frequency. Conclusions: Perioperative PIC is prevalent among the majority of GAM patients at our institution, with age, psychiatric diagnosis, and postoperative drain use identified as significant predictors. To mitigate PIC frequency, it is crucial to ensure adequate support staffing and provide comprehensive postoperative instructions, particularly concerning activity restrictions and drainage management. These interventions may reduce PICs in high-volume centers. Further research should investigate targeted interventions to further support TGNB patients during the perioperative period.

Surgical techniques and outcomes of thyroid chondroplasty in transfeminine individuals: A systematic review.

Thyroid chondroplasty (TC) in facial gender-affirming surgery (FGAS) is aimed at modifying the thyroid cartilage to achieve a more feminine laryngeal appearance. This study evaluated open versus endoscopic techniques to TC and associated outcomes and complications. A systematic review (SR) of articles pertaining to TC was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Twelve articles representing 368 patients were included for analysis. Nine articles described open approaches, and three articles described endoscopic techniques. The rate of total complications was 4.3% (n = 12) in the open approach compared to 15% (n = 13) in the endoscopic approach. Positive esthetic results were reported in 92% of cases performed with the open approach and 90% with the endoscopic approach. In the open approach, seven (2.5%) patients requested additional removal of cartilage, and three (1.1%) requested scar revision. In the endoscopic approach, three (3.7%) patients requested additional cartilage removal. In addition, data of individuals who underwent "cervical tracheoplasty" for gender dysphoria from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was reviewed, and there was no incidence of wound or major complications among patients who underwent tracheoplasty alone. Although the advantage of the endoscopic approach is a scarless neck incision, the rate of complications is higher with the open approach. Endoscopic approaches are still not widely used, and continued investigations are warranted to improve familiarity with this approach and reduce postoperative complications.

Perioperative misgendering experiences in patients undergoing gender-affirming surgery: a call for a gender-inclusive healthcare environment.

Background: Transgender individuals have long experienced discrimination and exclusion from medicine. Misgendering occurs when an individual is referred to using a gender or address incongruent with their identity. We evaluated the incidence of misgendering throughout the perioperative experience for patients undergoing gender-affirming surgery (GAS). Methods: Patients diagnosed with gender dysphoria who previously received GAS by the senior author were contacted to complete an IRB-approved survey to evaluate instances of misgendering while in the hospital for GAS. Study results were summarized using descriptive statistics. Results: Of 471 patients contacted, 182 completed the survey (38.6%). The most cited gender identity was transfemale (28.0%). Most patients reported respect for their gender identity (60.4%) and name (76.8%) during their perioperative experience. Twenty-two percent cited triggering experiences, and 15.4% reported interactions with healthcare employees causing them to reach out to a support system. Misgendering most commonly included incorrect use of patients' preferred names and/or pronouns (n = 50, 86.2%), most commonly at surgical check-in (n = 10, 45.5%). Recommendations to improve feelings of gender congruence during patients' stay included updated names and gender identities in electronic medical records (80.8%), and names and pronouns listed on curtains and doors (52.3%) and name tags (51.5%). Conclusions: Until now, the exact incidence of misgendering among patients seeking GAS have not been well established. Despite high levels of satisfaction, a large proportion still reported serious instances of misgendering. Improvements must be made to the perioperative experience to reduce misgendering and provide support and comfort during the sensitive period surrounding patients' gender transition.Level of evidence: Not gradable.

Selecting a chest masculinization plastic surgeon: a survey of transgender patients.

Background: Chest masculinization is a commonly performed gender-affirming procedure in transmasculine and non-binary patients and has increased in prevalence in recent years despite continued barriers to surgical care. With the expansion of insurance coverage and trained surgeons, patients at times have the opportunity to be selective in choosing their gender-affirming surgeon. This study aimed to investigate factors that transmasculine individuals consider important when selecting their chest masculinization plastic surgeon. Methods: All patients who underwent chest masculinization with a single surgeon between January 2018 and December 2021 were surveyed via an online questionnaire to rate 21 factors associated with surgeon selection. Multiple-choice questions and free text space were included to further clarify patient preferences. Results were analyzed to rate factors in order of importance. Results: One hundred three individuals completed the survey, generating a response rate of 49.5%. Average patient age at time of surgery was 27.0 years, and 2.0% of patients had prior gender affirmation surgery (GAS). The top five most important factors were surgeon specialization in GAS, insurance coverage, board certification, number of times surgeon has performed procedure, and availability of Before and After photographs. The five least important factors were age of surgeon, medical publications, availability of YouTube videos, location of training, and surgeon presence on social media. Conclusions: Transmasculine patients employ distinct criteria when selecting a chest masculinization gender-affirming plastic surgeon. An improved understanding of these factors informs providers of ways to enhance patient access to information and gender-affirming care.Level of evidence: Not gradable.

Intra-operative evaluation of textured anatomic implant rotation: a prospective study.

BACKGROUND: Textured implants were developed with the goal of reducing rates of capsular contracture and preventing implant malposition (eg., malrotation). Recent evidence has questioned whether textured implants are as resistant to malrotation as previously reported. METHODS: Women presenting to a single healthcare system for removal of textured implants were prospectively enrolled in the study from September 2019 to July of 2022. Patients who underwent removal of an anatomic, textured implant in the operating room were included in the study, while those who did not undergo implant removal, or were found to have a smooth implant, or a round, textured implant were excluded. The degree of implant rotation upon removal of the implant was measured intra-operatively. Implant specific factors, as well as patient demographics, clinical factors, and operative characteristics were collected. RESULTS: A total of 51 patients (80 implants) were included in the study. 45% of implants were malrotated (rotated >30 degrees) and the median degree of rotation was 30. Having more than one previous revision of the breast pocket was predictive of implant rotation (42 degrees) on multivariate linear regression analysis. Patients who presented with a complaint of "aesthetic dissatisfaction" had 2.89 increased odds of having an implant rotated > 30 degrees. CONCLUSION: Our study found a high rate of malrotation of textured, shaped implants upon explantation.

Hydrophilic polymers enhance early functional outcomes after nerve autografting.

BACKGROUND: Approximately 12% of operations for traumatic neuropathy are for patients with segmental nerve loss, and less than 50% of these injuries obtain meaningful functional recovery. Polyethylene glycol (PEG) therapy has been shown to improve functional outcomes after nerve severance, and we hypothesized this therapy could also benefit nerve autografting. METHODS: We used a segmental rat sciatic nerve injury model in which we repaired a 0.5-cm defect with an autograft using microsurgery. We treated experimental animals with solutions containing methylene blue (MB) and PEG; control animals did not receive PEG. We recorded compound action potentials (CAPs) before nerve transection, after solution therapy, and at 72 h postoperatively. The animals underwent behavioral testing at 24 and 72 h postoperatively. After we euthanized the animals, we fixed the nerves, sectioned and immunostained them to allow for quantitative morphometric analysis. RESULTS: The introduction of hydrophilic polymers greatly improved morphological and functional recovery of rat sciatic axons at 1-3 d after nerve autografting. Polyethylene glycol therapy restored CAPs in all animals, and CAPs were still present 72 h postoperatively. No CAPS were detectable in control animals. Foot Fault asymmetry scores and sciatic functional index scores were significantly improved for PEG therapy group at all time points (P < 0.05 and P < 0.001; P < 0.001 and P < 0.01). Sensory and motor axon counts were increased distally in nerves treated with PEG compared with control (P = 0.019 and P = 0.003). CONCLUSIONS: Polyethylene glycol therapy improves early physiologic function, behavioral outcomes, and distal axonal density after nerve autografting.

Preoperative anemia predicts thrombosis and free flap failure in microvascular reconstruction.

Patients undergoing microvascular reconstruction are often anemic from a combination of iatrogenic hemodilution and acute blood losses. No major clinical study describes the impact of preoperative anemia on free flap morbidity. The plastic surgery service at a high-volume academic center performed 156 free flaps among 147 patients from December 2005 to December 2010. One hundred thirty-two had a preoperative hemoglobin (Hb) or hematocrit (Hct), with mean values of 11.8±2.4 g/dL and 35.2%±7.0%, respectively. The overall failure rate was 9% (12/132), primarily from vascular thrombosis (6/12). Through logistic regression analysis, Hb and Hct were significant predictors of flap failure (P<0.005) and vascular thrombosis (P<0.05). Fisher exact test revealed a significant increase in failure risk at Hct level less than 30% (Hb<10 g/dL) (relative risk, 4.76, P=0.006), and probit analysis demonstrated an exposure-response relationship to decreased Hct level (P<0.005). These findings support that preoperative anemia could significantly impact free flap morbidity.
