Predictors of Long-Term Protraction Headgear Success in Patients With Cleft Lip and Palate: A 5-Year Follow-Up.

Patients with cleft lip and palate (CLP) characteristically present with maxillary hypoplasia and class III malocclusion. Protraction headgear (PHG) is a commonly used treatment for this type of malocclusion, with the goal of reducing future surgical needs. The purpose of this study was to evaluate the long-term effects of PHG treatment and determine the pretreatment predictors of long-term PHG success in patients with CLP. Twenty-nine patients with CLP who had undergone PHG treatment from 2012 to 2017 at a single institution were retrospectively analyzed. Patients were included if they had a lateral cephalogram or CBCT before, immediately after, and at least 5 years after their PHG treatment. Patients were divided into surgery and nonsurgery groups based on their 5-year follow-up clinical presentation. Student t tests, Wilcoxon signed-rank test, and a multivariate logistic regression model were used to compare pretreatment and post-treatment changes in both groups. Immediately post-treatment, the maxilla advanced 2.6 mm, the maxillary dentition advanced 4.7 mm, and the mandible rotated downward 5.0 mm and backward 2.6 mm. At long-term follow up the maxilla advanced 0.0 mm while the mandible advanced an additional 7.5 mm. Thus, PHG treatment is effective at improving class III malocclusion in the short term, but may not prevent future surgical need for patients with more severe skeletal discrepancies. Variables predictive of future surgical need include ANB, anterior facial height, overjet, and starting age of treatment, with ANB as the most reliable early predictor.

Comparison of the Effects of Postoperative Arm Restraints and Mittens on Cleft Lip Scar Quality after Primary Repair.

Introduction: Postoperative management following primary cleft lip repair varies across institutions, cleft care teams, and individual surgeons. Postoperative precautions employed after cleft lip repair include dietary restrictions, pacifier limitations, and immobilization, with arm restraints long being used. Yet, restraint distress has led to the exploration of other forms of immobilization. Thus, this study aims to assess cleft lip scar quality and complication rates after postoperative immobilization with arm restraints versus hand mittens. Methods: A retrospective review of patients with unilateral cleft who underwent primary repair with the senior surgeon was done. Data on demographics, surgical characteristics, and immobilization utilized were gathered. A survey with pictures of postoperative scars were sent to laypeople who assessed scar quality with Modified Scar-Rating Scale scores for surface appearance, height, and color of the scar tissue. Statistical analysis was carried out for significance. Results: Twenty-eight patients with a unilateral cleft underwent arm restraints after primary lip repair, and twenty-seven utilized mittens. In total, 42 medical students completed the scar assessment. Photographs were taken an average of 23.9 (±5.8) and 28.2 (±11.9) months postoperatively in the restraint and mitten groups, respectively (p = 0.239). There were no statistically significant differences in scores between scar surface, height, color, or overall scar appearance. Complication rates were also similar between groups. Conclusions: Arm restraints appear to have no additional benefit relative to scar quality, as compared to mittens. Considering the arm restraints' burden of care, mittens should be considered as a measure to protect the lip after primary repair.

Change in Lower Lip Position After Le Fort I Advancement in Patients with Bilateral vs. Unilateral Cleft Lip and Palate.

To compare lower lip changes after Le Fort I advancement surgery in patients with a cleft.Single institution, retrospective review.Academic tertiary referral hospital.Skeletally mature patients with a cleft who underwent one-piece Le Fort I advancement surgery who had a lateral cephalogram or cone-beam computed tomography (CBCT) scan preoperatively and at least 6 months postoperatively. Patients who underwent concomitant mandibular surgery or genioplasty were excluded. 64 patients were included: 45 male and 19 female, 25 with BCLP and 39 with UCLP. The mean age at surgery was 18.4 years.Single jaw one-piece Le Fort I advancement surgery.Standard lateral cephalometric landmarks of the bony skeleton and soft tissue were compared before and after Le Fort I advancement. Pearson correlation coefficients (r) were calculated to measure the correlation between lower lip position and other soft and hard tissue changes.After comparable maxillary advancements [BCLP: 7.2 mm (95% CI: 6.2-8.3 mm), UCLP: 6.4 mm (95% CI: 5.7-7.0 mm)] the horizontal upper-to-lower lip discrepancy significantly improved in both groups. The lower lip became thinner and more posteriorly positioned. Changes in lower lip position correlated strongly with mandibular bony landmarks and moderately with upper lip position, but poorly with maxillary landmarks.Le Fort I advancement results in posterior displacement of the lower lip and better lip competence, thereby improving facial harmony. This lower lip change is not predictable by degree of maxillary advancement, and does not differ in patients with BCLP vs. UCLP.

Contemporary Prevalence of Oral Clefts in the US: Geographic and Socioeconomic Considerations.

Background: Socio-economic status, living environments, and race have been implicated in the development of different congenital abnormalities. As orofacial clefting is the most common anomaly affecting the face, an understanding of its prevalence in the United States and its relationship with different determinants of health is paramount. Therefore, the purpose of this study is to determine the modern prevalence of oral-facial clefting in the United States and its association with different social determinants of health. Methods: Utilizing Epic Cosmos, data from approximately 180 US institutions were queried. Patients born between November 2012 and November 2022 were included. Eight orofacial clefting (OC) cohorts were identified. The Social Vulnerability Index (SVI) was used to assess social determinants of health. Results: Of the 15,697,366 patients identified, 31,216 were diagnosed with OC, resulting in a prevalence of 19.9 (95% CI: 19.7-20.1) per 10,000 live births. OC prevalence was highest among Asian (27.5 CI: 26.2-28.8) and Native American (32.8 CI: 30.4-35.2) patients and lowest among Black patients (12.96 CI: 12.5-13.4). Male and Hispanic patients exhibited higher OC prevalence than female and non-Hispanic patients. No significant differences were found among metropolitan (20.23/10,000), micropolitan (20.18/10,000), and rural populations (20.02/10,000). SVI data demonstrated that OC prevalence was positively associated with the percentage of the population below the poverty line and negatively associated with the proportion of minority language speakers. Conclusions: This study examined the largest US cohort of OC patients to date to define contemporary US prevalence, reporting a marginally higher rate than previous estimates. Multiple social determinants of health were found to be associated with OC prevalence, underscoring the importance of holistic prenatal care. These data may inform clinicians about screening and counseling of expectant families based on socio-economic factors and direct future research as it identifies potential risk factors and provides prevalence data, both of which are useful in addressing common questions related to screening and counseling.

Association of Commonly Prescribed Antepartum Medications and Incidence of Orofacial Clefting.

BACKGROUND: Pharmacologic agents are often used in the antepartum period, however, studies on their effect on fetal development are limited. Thus, this study aims to examine the effect of commonly prescribed antepartum medications on the development of orofacial clefting. METHODS: Utilizing EPIC Cosmos deidentified data from approximately 180 US institutions was queried. Patients born between January 1, 2013, to January 1, 2023, were included. Eight OC cohorts were identified. Gestational medication use was identified by medications prescribed, provider-administered, or reported use by mothers. Medications used in at least 1 in 10,000 pregnancies were included in this analysis. RESULTS: A total of 12 098 newborns with available maternal pharmacologic data were born with any type of orofacial clefting. Prevalence for all oral clefts, any cleft palate, and any cleft lip were 20.56, 18.10, and 10.60 per 10 000 individuals, respectively. Notable significant exposures include most anticonvulsants, such as lamotrigine (OR1.33, CI 1.10-1.62), and topiramate (OR1.35, CI 1.13-1.62), as well as nearly all SSRIs/SNRIs, including fluoxetine (OR1.34, CI 1.19-1.51), sertraline (OR1.25, CI 1.16-1.34), and citalopram (OR1.28, CI 1.11-1.47). Corticosteroids were also correlated including dexamethasone (OR1.19, CI 1.12-1.27), and betamethasone (OR1.64, CI 1.55-1.73), as were antibiotics, including amoxicillin (OR1.22, CI 1.14-1.30), doxycycline (OR1.29, CI 1.10-1.52), and nitrofuran derivatives (OR1.10, CI 1.03-1.17). CONCLUSION: New associations between commonly prescribed antepartum medications and orofacial clefting were found. These findings should be confirmed as causality is not assessed in this report. Practitioners should be aware of the potential increased risk associated with these medications.

Virtual Reality Simulation of Airway Management Post-Cleft Palate Surgery: A Model for Sustainable and Equitable Education.

BACKGROUND: The effectiveness of virtual-reality (VR) simulation-based training in cleft surgery has not been tested. The purpose of this study was to evaluate learners' acceptance of VR simulation in airway management of a pediatric patient post-cleft palate repair. METHODS: This VR simulation was developed through collaboration between BioDigital and Smile Train. 26 medical students from a single institution completed 10 min of standardized VR training and 5 min of standardized discussion about airway management post-cleft palate repair. They spent 4-8 min in the VR simulation with guidance from a cleft surgery expert. Participants completed pre- and post-surveys evaluating confidence in using VR as an educational tool, understanding of airway management, and opinions on VR in surgical education. Satisfaction was evaluated using a modified Student Evaluation of Educational Quality questionnaire and scored on a 5-point Likert scale. Wilcoxon signed-rank tests were performed to evaluate responses. RESULTS: There was a significant increase in respondents' confidence using VR as an educational tool and understanding of airway management post-cleft palate repair after the simulation (P < .001). Respondents' opinions on incorporating VR in surgical education started high and did not change significantly post-simulation. Participants were satisfied with VR-based simulation and reported it was stimulating (4.31 ± 0.88), increased interest (3.77 ± 1.21), enhanced learning (4.12 ± 1.05), was clear (4.15 ± 0.97), was effective in teaching (4.08 ± 0.81), and would recommend the simulation (4.2 ± 1.04). CONCLUSION: VR-based simulation can significantly increase learners' confidence and skills in airway management post-cleft palate repair. Learners find VR to be effective and recommend its incorporation in surgical education.

Transpalpebral/Blepharoplasty Incision and Supraorbital Craniotomy for the Treatment of Ethmoidal Dural Arteriovenous Fistulas: A Case Series.

BACKGROUND AND OBJECTIVES: Inherent complex angioarchitecture associated with ethmoidal dural arteriovenous fistulas (dAVFs) can make endovascular treatment methods challenging. Many surgical approaches are accompanied by unfavorable cosmetic results such as facial scarring. Blepharoplasty incision of the eyelid offers a minimal, well-hidden scar compared with other incision sites while offering the surgeon optimal visualization of pathogenic structures. This case series aims to report an initial assessment of the safety and efficacy of supraorbital craniotomy by blepharoplasty transpalpebral (eyelid) incision for surgical disconnection of ethmoidal dAVFs. METHODS: Retrospective chart review was conducted for all patients who underwent blepharoplasty incision and craniotomy for disconnection of ethmoidal dAVFs at our institution between October 2011 and February 2023. Patient charts and follow-up imaging were reviewed to report clinical and angiographic outcomes as well as periprocedural and follow-up complications. RESULTS: Complete obliteration and disconnection of ethmoidal dAVF was achieved in all 6 (100%) patients as confirmed by intraoperative angiogram with no resulting morbidity or mortality. Periprocedural complications included one case of transient nasal cerebrospinal fluid leak that was self-limiting and resolved before discharge without intervention. CONCLUSION: Surgical treatment for ethmoidal dAVFs, specifically by transpalpebral incision and supraorbital craniotomy, is a safe and effective treatment option and affords the surgeon greater access to the floor of the anterior fossa when necessary. In addition, blepharoplasty incision addressed patient concerns for facial scarring compared with other incision sites by creating a more well-hidden, minimal scar in the natural folds of the eyelid for patients with an eyelid crease.

Internet-based Digital Simulation for Cleft Surgery Education: A 10-year Assessment of Demographics, Usage, and Future Directions.

Background: In October 2012, an open-access, multimedia digital cleft simulator was released. Its purpose was to address global disparities in cleft surgery education, providing an easily accessible surgical atlas for trainees globally. The simulator platform includes a three-dimensional surgical simulation of cleft care procedures, intraoperative videos, and voiceover. This report aims to assess the simulator's demographics and usage in its tenth year since inception. Finally, we also aim to understand the traction of virtual reality in cleft surgical education. Methods: Usage data of the simulator over 10 years were retrospectively collected and analyzed. Data parameters included the number of users, sessions, countries reached, and content access. An electronic survey was emailed to registered users to assess the benefits of the simulator. Results: The total number of new and active simulator users reached 7687 and 12,042. The simulator was accessed an average of 172.9.0 ± 197.5 times per month. Low- to middle-income regions accounted for 43% of these sessions. The mean session duration was 11.4 ± 6.3 minutes, yielding a total screen time of 3022 hours. A total of 331 individuals responded to the survey, of whom 80.8% found the simulator to be very useful or extremely useful. Of those involved in education, 45.0% implemented the simulator as a teaching tool. Conclusions: Global utilization of the simulator has been sustained after 10 years from inception with an increased presence in low- to middle-income nations. Future similar surgical simulators may provide sustainable training platforms to surgeons in low- and high-resource areas.

LeFort I Horizontal Osteotomy: Defining the Feasibility of the "High Osteotomy".

OBJECTIVE: To define "high osteotomy" and determine the feasibility of performing this procedure. DESIGN: Single institution, retrospective review. SETTING: Academic tertiary referral hospital. PATIENTS, PARTICIPANTS: 34 skeletally mature, nonsyndromic patients with unilateral CLP who underwent Le Fort I osteotomy between 2013 and 2020. Patients with cone-beam computed tomography (CBCT) scans completed both pre- (T1) and post-operatively (T2) were included. Patients with bilateral clefts and rhinoplasty prior to post-operative imaging were excluded. INTERVENTIONS: Single jaw one-piece Le Fort I advancement surgery. MAIN OUTCOME MEASURES: Measurements of the superior ala and inferior turbinates were taken from the post-operative CBCT. RESULTS: The sample included 26 males and 8 females, 12 right- and 22 left-sided clefts. The inferior turbinates are above the superior alar crease at a rate of 73.53% and 76.48% on the cleft and non-cleft sides, respectively. One (2.9%) osteotomy cut was above the level of the cleft superior alar crease, and no cuts were above the level of the non-cleft superior ala. On average, the superior ala was 2.63 mm below the inferior turbinates. The average vertical distances from the superior alar crease and the inferior turbinates to the base of the non-cleft side pyriform aperture were 12.17 mm (95% CI 4.00-20.34) and 14.80 mm (95% CI 4.61-24.98), respectively. To complete a "high osteotomy," with 95% confidence, the cut should be 20.36 mm from the base of the pyriform aperture. CONCLUSIONS: A "high" osteotomy is not consistently possible due to the relationship between the superior alar crease and the inferior turbinate.

Long-Term Outcomes in Prepectoral versus Subpectoral Two-Stage Implant-Based Breast Reconstruction after Nipple-Sparing Mastectomy.

BACKGROUND: Implant-based breast reconstruction remains the most often used method following mastectomy, but data are lacking regarding differences in complications and long-term patient-reported outcomes for two-stage subpectoral versus prepectoral reconstruction. This study sought to better understand the risks and impact of these reconstructive approaches on overall satisfaction. METHODS: Patients who underwent unilateral or bilateral nipple-sparing mastectomy and two-stage implant-based reconstruction from 2014 to 2019 were identified from the electronic medical records and contacted via email to complete the BREAST-Q survey. Overall satisfaction was measured by the question, "How happy are you with the outcome of your breast reconstruction?" using a six-point Likert scale. Patients were grouped into subpectoral or prepectoral cohorts. Complications were evaluated retrospectively. Only patients who were at least 6 months from their final reconstruction were included in the analysis. RESULTS: Of the 582 patients contacted, 206 (35%) responded. The subpectoral ( n = 114) and prepectoral ( n = 38) groups did not differ significantly by demographic or treatment characteristics. BREAST-Q scores were also comparable. Complication rates were similar, but prepectoral patients had a significantly higher rate of capsular contracture (16% versus 4%, P < 0.05). Bivariate ordered logistic regression identified prepectoral implant placement, having any postoperative complication, and capsular contracture as predictors of less overall happiness. CONCLUSIONS: The authors' study suggests that prepectoral patients may have slightly higher complication rates but are as satisfied as subpectoral patients after at least a year of follow-up. Further studies should investigate risk factors for capsular contracture, how the risk changes over time, and how the risk affects patient satisfaction.

Gender-Affirming Facial Feminization Surgery at a Public, Safety-Net Hospital: A Single-Center Early Experience.

BACKGROUND: Facial feminization surgery (FFS) remains inaccessible to many transgender patients. Zuckerberg San Francisco General Hospital (ZSFG) was among the first public, safety-net hospitals to perform FFS. The purpose of this study is to examine the postoperative outcomes of patients who underwent FFS at ZSFG and describe barriers to providing FFS in a public hospital setting. METHODS: A retrospective review identified patients who underwent FFS at ZSFG. Demographic data, comorbidity profiles, postoperative outcomes, and hospital utilization data were collected from the medical records. FACE-Q modules (scored 0-100) were used to survey patient satisfaction at least 1 year postoperatively. RESULTS: Seventeen patients underwent comprehensive FFS surgery at ZSFG. The median age was 41 years [interquartile range (IQR): 38-55], median body mass index was 26.4 (IQR: 24.1-31.3). Patients underwent a median of 9 procedures, the most common of which included frontal cranioplasty (n=13, 77%), open brow lift (n=13, 77%), rhinoplasty (n=12, 71%), and mandible contouring (n=12, 71%). There were no complications, readmissions, or reoperations within 30 days. Patients reported high satisfaction with the surgical outcome (median: 87, IQR: 87-100), excellent postoperative psychological functioning (median: 100, IQR: 88-100), and low levels of appearance-related distress (median: 3, IQR: 0-35). An estimated 243 operating room hours and 51 inpatient bed days were required to cover all FFS procedures. CONCLUSIONS: Performing FFS in a public, safety-net hospital was associated with zero postoperative complications, few revision procedures, and excellent patient satisfaction. Limited operating room hours and inpatient availability represented barriers to providing FFS in this setting.

Disparities in Timing of Alveolar Bone Grafting and Dental Reconstruction in Patients With Clefts.

This study sought to identify disparities in the timing of alveolar bone grafting (ABG) surgery and the replacement strategy for missing maxillary lateral incisors for patients with clefts.A retrospective record review identified patients who underwent ABG. Multivariable regression analyzed the independent contribution of each variable.This institutional study was performed at the University of California, San Francisco.Patients who presented under age 12 and underwent secondary ABG between 2012 and 2020 (n = 160).The age at secondary ABG and the recommended dental replacement treatment for each patient, either dental implantation or canine substitution.The average age at ABG was 10.8 ± 2.1 years, 106 (66.3%) patients were not White, and 80 (50.0%) had private insurance. Independent predictors of older age at ABG included an income below $ 50 000 as estimated from ZIP code (ß = 15.0 months, 95% CI, 5.7-24.3, P = .002) and identifying as a race other than White (ß = 10.1 months, 95% CI, 2.1-18.0, P = .01). After ABG, patients were more likely to undergo dental implantation over canine substitution if they were female (odds ratio [OR] = 4.3, 95% CI, 1.3-17.1, P = .02) or had private insurance (OR = 12.5, 95% CI, 2.2-143.2, P = .01).Patients who were low-income or not White experienced delays in ABG, whereas dental implantation was more likely to be recommended for patients with private insurance. Understanding the sources of disparities in dental reconstruction of cleft deformities may reveal opportunities to improve equity.

Racial and Socioeconomic Disparities in Prompt Craniosynostosis Workup and Treatment.

The purpose of this study was to identify racial and socioeconomic disparities in craniosynostosis evaluation and treatment, from referral to surgery. Patients diagnosed with craniosynostosis between 2012 and 2020 at a single center were identified. Chart review was used to collect demographic variables, age at referral to craniofacial care, age at diagnosis, age at surgery, and surgical technique (open versus limited incision). Multivariable linear and logistic regression models with lasso regularization assessed the independent effect of each variable. A total of 298 patients were included. Medicaid insurance was independently associated with a delay in referral of 83 days [95% confidence interval (CI) 4-161, P=0.04]. After referral, patients were diagnosed a median of 21 days later (interquartile range 7-40), though this was significantly prolonged in patients who were not White (ß 23 d, 95% CI 9-38, P=0.002), had coronal synostosis (ß 24 d, 95% CI 2-46, P=0.03), and had multiple suture synostosis (ß 47 d, 95% CI 27-67, P<0.001). Medicaid insurance was also independently associated with diagnosis over 3 months of age (risk ratio 1.3, 95% CI 1.1-1.4, P=0.002) and undergoing surgery over 1 year of age (risk ratio 3.9, 95% CI 1.1-9.4, P=0.04). In conclusion, Medicaid insurance was associated with a 3-month delay in referral to craniofacial specialists and increased risk of diagnosis over 3 months of age, limiting surgical treatment options in this group. Patients with Medicaid also faced a 4-fold greater risk of delayed surgery, which could result in neurodevelopmental sequelae.

Superior Long-term Appearance of Strip Craniectomy Compared with Cranial Vault Reconstruction in Metopic Craniosynostosis.

BACKGROUND: Strip craniectomy with orthotic helmet therapy (SCOT) is an increasingly supported treatment for metopic craniosynostosis, although the long-term efficacy of deformity correction remains poorly defined. We compared the longterm outcomes of SCOT versus open cranial vault reconstruction (OCVR). METHODS: Patients who underwent OCVR or SCOT for isolated metopic synostosis with at least 3 years of follow-up were identified at our institution. Anthropometric measurements were used to assess baseline severity and postoperative skull morphology. Independent laypersons and craniofacial surgeons rated the appearance of each patient's 3D photographs, compared to normal controls. RESULTS: Thirty-five patients were included (15 SCOT and 20 OCVR), with similar follow-up between groups (SCOT 7.9 ± 3.2 years, OCVR 9.2 ± 4.1 years). Baseline severity and postoperative anthropometric measurements were equivalent. Independent adolescent raters reported that the forehead, eye, and overall appearance of SCOT patients was better than OCVR patients (P < 0.05, all comparisons). Craniofacial surgeons assigned Whitaker class I to a greater proportion of SCOT patients with moderate-to-severe synostosis (72.2 ± 5.6%) compared with OCVR patients with the same severity (33.3 ± 9.2%, P = 0.02). Parents of children who underwent SCOT reported equivalent satisfaction with the results of surgery (100% versus 95%, P > 0.99), and were no more likely to report bullying (7% versus 15%, P = 0.82). CONCLUSIONS: SCOT was associated with superior long-term appearance and perioperative outcomes compared with OCVR. These findings suggest that SCOT should be the treatment of choice for patients with a timely diagnosis of metopic craniosynostosis.

The Incidence of Breast Cancer After Gender-Affirming Mastectomy in Transmen.

BACKGROUND: The incidence of breast cancer in transmale patients and their continued risk after gender-affirming mastectomy (GAM) has not been well established. Plastic surgeons who offer GAM are often one of the few medical professionals sought out by this population, placing them in a unique position to not only deliver surgical care but also improve access to preventative cancer care. METHODS: We reviewed the senior author's experience with GAMs over the past 5 years for any incidence of breast cancer noted after or at time of surgery. We subsequently performed a thorough review of the literature for cases of breast cancer in transmen, to provide a comprehensive overview of screening, therapy, and postoperative surveillance practices. RESULTS: We identified 2 cases of breast cancer (ages 49 and 54 years) found on routine examination of pathology specimens after GAM at our institution. Both patients had been taking hormone therapy for the past 1 year. Pathology specimen revealed low-grade estrogen receptor-/progesterone receptor-positive ductal carcinoma in situ in 1 patient, and estrogen receptor-/progesterone receptor-positive invasive ductal carcinoma in the other. Both patients were referred to oncology for appropriate treatment, and both elected to continue their exogenous hormone therapy for personal reasons.Review of the literature demonstrated 36 other cases of documented breast cancer in transmen. Sixty-seven percent (24) were found after GAM, and of those, 50% were incidentally found on pathology specimen. At least 50% were found to be either estrogen-, progesterone-, or androgen receptor-positive cancers. At least 17% of cases documented continued use of masculinizing hormone therapy after cancer diagnosis. CONCLUSIONS: Most documented cases of breast cancer in transmen were diagnosed after gender-affirming surgery, which would suggest residual breast tissue does pose some risk for breast cancer. In addition, those diagnosed with cancer may elect to continue exogenous testosterone therapy despite potential added risks with hormone-receptor positivity. These cases highlight the need for agreement in current screening practices, surgical recommendations, and continuation of masculinizing hormone therapy.Plastic surgeons have the unique opportunity to educate these patients on appropriate breast cancer-related surveillance both before and after chest surgery.

Quantifying the Psychosocial Benefits of Masculinizing Mastectomy in Trans Male Patients with Patient-Reported Outcomes: The University of California, San Francisco, Gender Quality of Life Survey.

BACKGROUND: Gender-affirming surgery is a medically necessary treatment to alleviate gender dysphoria for transgender patients. Although previous studies suggest improved psychosocial outcomes after gender-affirming surgery, there are no transgender-specific instruments available to assess its effects on patient quality of life. METHODS: Using qualitative methods, the authors developed the first quality-of-life survey, the University of California, San Francisco, Gender Quality of Life (UCSF Gender QoL) survey, for trans male patients undergoing gender-affirming mastectomy. The UCSF Gender QoL survey was then administered prospectively to 51 trans male patients undergoing inframammary mastectomy with free nipple grafting at the University of California, San Francisco. The brief version of the World Health Organization Quality of Life survey was also given as a measure of external validity. The Cronbach alpha was value calculated to measure internal validity. RESULTS: Thirty-six patients completed surveys 6 weeks after surgery, and 22 patients completed surveys 1 year after surgery, for response rates of 71 percent and 43 percent, respectively. The UCSF Gender QoL survey detected a significant improvement in quality of life 6 weeks and 1 year after chest surgery. The effect sizes were large, and the Cronbach alpha exhibited excellent internal validity. CONCLUSIONS: This study establishes the UCSF Gender QoL survey as one of the first patient-reported outcomes tools for evaluating quality of life in trans male patients after gender-affirming chest reconstruction. Although the study is limited by a small cohort at a single center, establishing the validity of the UCSF Gender QoL survey provides an invaluable tool for future research into various aspects of gender-affirming chest surgery.

A Dual-Surgeon Approach to Breast Cancer Surgery in a Transmale.

ABSTRACT: With increasing numbers of gender-affirming chest surgery, new questions regarding breast cancer management and surgical practice arise. Guided by our case report, we present a comprehensive review of breast cancer surgery in a transman to educate both plastic and breast surgeons on various factors to consider when caring for these patients.Our case involves a 31-year-old transmale patient who presented for plastic surgery consultation for gender-affirming mastectomy but was subsequently found to have a right breast mass. This is the first case in the literature of a transmale on hormone therapy with breast cancer interested in gender-affirming surgery, thus requiring a dual-surgeon approach for oncologic and gender-affirming mastectomy. With a multidisciplinary patient-centered approach involving breast surgery, plastic surgery, medical oncology, and radiology, we devised a surgical plan to safely remove his breast tissue with consideration for his gender-affirming goals. He underwent a right skin-sparing mastectomy with sentinel node biopsy and left prophylactic skin-sparing mastectomy through skin markings by the plastic surgeon, with bilateral free nipple grafts. Final pathology confirmed estrogen and progesterone receptor-positive and androgen receptor-positive invasive ductal carcinoma with clear margins and negative sentinel node. The patient did not require adjuvant chemotherapy or radiation but was started on adjuvant hormone therapy targeting his hormone receptor positive cancer. He elected to stay on low-dose masculinizing hormone therapy with continued surveillance examinations.We follow our case with a review of the current literature involving breast cancer in transmales to explore current screening practices, surgical recommendations, adjuvant therapies, continuation of masculinizing hormone therapy, and postoperative surveillance guidelines in the hopes of informing plastic surgeons in having these discussions with their transmale patients and thus improving informed cancer care for this population.

The Breast Response to Estrogenic Stimulation in Transwomen Classification: Evaluation of Breast Response to Estrogenic Stimulation in Transwomen.

BACKGROUND: Hormone therapy with exogenous estrogen and/or spironolactone is commonly used in transfemales to induce breast development. However, inherent differences in adult male and female anatomy create persistent deformities and inadequate gender congruency despite glandular breast development. This includes nipple characteristics, position of inframammary fold, and the distribution of breast tissue. Accordingly, the Tanner stages do not accurately reflect these persistent deformities because they relate to breast development in transwomen. Herein, we describe a classification system for breast development in transwomen treated with hormone therapy. METHODS: Ninety-nine transfemale patients who underwent breast augmentation from 2014 to 2018 were retrospectively reviewed and categorized using a novel scheme, the Breast Response to Estrogenic Stimulation in Transwomen (BREST) scale. Preoperative demographics, anatomic measurements, surgical technique, and postoperative results were also compared among BREST types. RESULTS: Most patients were rated as BREST type II (25%) or type IV (37%). The BREST scale exhibited moderate interrater reliability (κ = 0.58) between 3 plastic surgeons. Objective breast measurements such as sternal notch-to-nipple distance and nipple-to-inframammary fold distance correlated with the BREST scale. Multivariate logistical regression identified the nipple-to-inframammary fold distance and different between the bust and chest circumference as the strongest predictors of BREST type (odds ratio, 2.57 and 1.96, respectively). Body mass index was not a predictor of BREST type after controlling for confound variables on multivariate analysis. CONCLUSIONS: The BREST scale uniquely captures the differences in breast phenotypes in transgender women according to hormone therapy response. Although some subjectivity exists with moderate interrater reliability, the BREST scale correlates with objective breast measurements. The BREST scale provides a transwoman-specific metric allowing for a common language in assessment of transgender breast development and optimal communication among providers, different specialties, and insurance companies.
