Osseointegrated Prosthetic Ear Reconstruction in Cases of Skin Malignancy: Technique, Outcomes, and Patient Satisfaction.

BACKGROUND: Ear reconstruction with osseointegrated prosthetic implants is a well-established method of reconstruction after resection of skin malignancies on the external ear. There is limited literature reporting technique, outcomes, and patient satisfaction. METHODS: We evaluated our outcomes over a 5-year period looking at osseointegrated prosthetic reconstruction after auriculectomy for external ear skin malignancies. We report demographics, disease characteristics, technique, and complications. The patients were surveyed looking at 6 domains: satisfaction, stability, comfort, ease of use, level of self-consciousness, and preoperative education. RESULTS: Of the 21 patients included in the study, 14 (67%) were treated for invasive melanoma (Breslow depth, >0.8mm), 4 (19%) for squamous cell carcinoma, 2 (10%) for basal cell carcinoma, and 1 (5%) for an atypical fibroxanthoma. Complications rates were low. There were no cases of infection, hematoma, or bleeding. In 2 patients (9.5%), 1 of the 3 implants failed to osseointegrate and was removed, but the prosthesis was able to be secured with the remaining 2 posts. There were 3 cases (14%) of delayed healing and 1 with excessive granulation tissue growth. Survey results showed high satisfaction in all measured domains. CONCLUSIONS: In cases of skin malignancy requiring total or subtotal auriculectomy, prosthetic ear reconstruction with osseointegrated implants is a good alternative to reconstruction with autologous tissue. Our experience demonstrates good outcomes and with low complication rates and high patient satisfaction.

Integrative analyses reveal signaling pathways underlying familial breast cancer susceptibility.

The signaling events that drive familial breast cancer (FBC) risk remain poorly understood. While the majority of genomic studies have focused on genetic risk variants, known risk variants account for at most 30% of FBC cases. Considering that multiple genes may influence FBC risk, we hypothesized that a pathway-based strategy examining different data types from multiple tissues could elucidate the biological basis for FBC. In this study, we performed integrated analyses of gene expression and exome-sequencing data from peripheral blood mononuclear cells and showed that cell adhesion pathways are significantly and consistently dysregulated in women who develop FBC. The dysregulation of cell adhesion pathways in high-risk women was also identified by pathway-based profiling applied to normal breast tissue data from two independent cohorts. The results of our genomic analyses were validated in normal primary mammary epithelial cells from high-risk and control women, using cell-based functional assays, drug-response assays, fluorescence microscopy, and Western blotting assays. Both genomic and cell-based experiments indicate that cell-cell and cell-extracellular matrix adhesion processes seem to be disrupted in non-malignant cells of women at high risk for FBC and suggest a potential role for these processes in FBC development.

Female-to-Male Chest Reconstruction: A Review of Technique and Outcomes.

PURPOSE: Female-to-male transgender individuals frequently seek out chest wall masculinization as part of their gender transition and to aid with treating gender dysphoria. Critical evaluation of techniques, complications, and outcomes is important particularly as the surgery becomes more commonly performed. METHODS: A retrospective review was performed of all patients undergoing female-to-male chest wall reconstruction by the senior author from 2008 to 2015. Charts were reviewed to evaluate patient demographics, intraoperative details, and postoperative outcomes. Complications were stratified into major and minor complications based on the need to return to the operating room. Inframammary fold techniques and periareolar techniques cohorts were compared for major complications, minor complications, and need for revision surgeries. RESULTS: Over 8 years, 130 patients were identified. One hundred ten patients underwent inframammary fold techniques, and 20 patients underwent periareolar incisions. Early postoperative complications occurred in 25% of patients. Hematoma was the most common complications, occurring in 14% of patients. Major complications occurred in 8% of patients. Minor complications occurred in 16% of patients, with respiratory problems found to be a significant risk factor. On long-term follow up, 9% of patients had a revision procedure performed. Patients with prior breast surgery were more likely to require revisions (P = 0.009). Of patients requiring revision, 38% had a periareolar incision, compared with only 13% of patients who did not (P = 0.03). For unplanned revisions, there was no difference in periareolar and inframammary techniques. CONCLUSIONS: Our patient cohort demonstrates that female-to-male patients who undergo chest wall contouring through a transverse inframammary fold incision with either composite or standard free nipple grafting have decreased rates of revision surgery and trend toward having lower complication rates as compared with periareolar and limited scar techniques. To best manage expectations, patients undergoing a periareolar or other limited incision technique are counseled regarding an increased risk of hematoma and an increased likelihood of revisions.

Creation of an Aesthetic Male Nipple Areolar Complex in Female-to-Male Transgender Chest Reconstruction.

BACKGROUND: Female-to-male chest wall reconstruction is becoming more common, but while there is a growing body of the literature describing technique and algorithms, little detail is written on methods for creating a male appearing nipple areolar complex (NAC) from a female NAC utilizing free nipple graft techniques. Incorrect positioning of the NAC on the chest wall and suboptimal shaping and sizing of the NAC are common pitfalls in male NAC creation. METHODS: With this paper, we present techniques for nipple grafting to achieve improved male appearing NACs, as well as a simple, reproducible method for appropriate placement of the NAC relative to the borders of the pectoralis muscle. To validate our technique, we performed photographic analysis of 64 NACs in 32 volunteers with BMI of 25 or less. RESULTS: The anatomic study determined the cis-male nipple to be positioned on average 2.5 cm medial to the lateral border of the pectoralis muscle and 2.4 cm above the inferior pectoralis insertion. This supports our surgical technique of positioning the NAC in relation to the pectoralis borders rather than previously advocated anatomic landmarks. We also present reliable techniques for creating a round or horizontally oval final NAC shape as well as a composite grafting technique for cases of large papillae. CONCLUSIONS: Our anatomic study supports placement of the male NAC relative to lateral and inferior borders of the pectoralis muscle. Nipple grafting techniques presented allow for a simple and reproducible method of creating an aesthetic male NAC shape in female-to-male transgender chest reconstruction.

Gender-Affirming Surgery in Adolescents and Young Adults: A Review of Ethical and Surgical Considerations.

BACKGROUND: The number of transgender adolescents seeking gender-affirming surgery (GAS) in increasing. Surgical care of the adolescent transgender patient is associated with several unique technical, legal, and ethical factors. The authors present a review of the current literature on gender-affirming surgery for individuals under the age of legal majority and propose directions for future research. METHODS: A scoping review of recent literature was performed to assess evidence on gender-affirming surgery in individuals under the age of legal majority. Articles were included that examined either ethical or technical factors unique to pediatric GAS. Study characteristics and conclusions were analyzed in conjunction with expert opinion. RESULTS: Twelve articles were identified that met inclusion criteria. Ten of these articles discussed ethical challenges in adolescent GAS, seven discussed legal challenges, and five discussed technical challenges. Ethical discussions focused on the principles of beneficence, nonmaleficence, and autonomy. Legal discussions centered on informed consent and insurance coverage. Technical discussions focused on the effects of puberty blockade on natal tissue. CONCLUSIONS: Surgical care of the adolescent transgender patient involves important ethical, legal, and technical considerations that must be addressed by the clinical team. As the population of individuals seeking GAS after puberty blockade increases, future research is needed describing functional and psychosocial outcomes in these individuals.

Preferences for and barriers to gender affirming surgeries in transgender and non-binary individuals.

Background: The transgender/non-binary community continues to be an underserved population in medicine, and our understanding of their interests, disinterests, and barriers to transition-related healthcare is quite limited, especially among the diverse gender identities within the transgender/non-binary umbrella. Aim: To determine the interests, disinterests and barriers to gender affirming surgeries for transgender men, transgender women and non-binary individuals of any birth-assigned sex. Methods: An anonymous, online survey using REDcap was applied across all 50 states and advertised through social media, healthcare organization websites and flyers. The responses of individuals greater than 18 years of age who identified as transgender or non-binary were analyzed. Results: Compared to the 2015 US Transgender Survey, interest in gender affirming surgeries was higher across all gender identities surveyed and for all procedures, by an average of 38%. Interest overall in gender affirming procedures varied greatly among gender identity groups as well as with age differences. Barriers were found to be a mixture of lack of resources for recovery, financial, and a fear of complications. Discussion: Our results highlight that a desire for these procedures is unique for each individual and should never be assumed for transgender/non-binary patients. In order to better aid this underserved population, the medical community must further work to mitigate the barriers to gender affirming procedures by decreasing cost, investigating ways to increase access to resources for recovery, and improving outcomes for each of the gender affirming surgeries.

Current Practices in the Pathologic Assessment of Breast Tissue in Transmasculine Chest Surgery.

BACKGROUND: No guidelines exist regarding management of breast tissue for transmasculine and gender-nonconforming individuals. This study aims to investigate the experiences and practices regarding perioperative breast cancer risk management among the American Society of Plastic Surgeons members performing chest masculinization surgery. METHODS: An anonymous, online, 19-question survey was sent to 2517 U.S.-based American Society of Plastic Surgeons members in October of 2019. RESULTS: A total of 69 responses were analyzed. High-volume surgeons were more likely from academic centers (OR, 4.88; 95 percent CI, 1.67 to 15.22; p = 0.005). Age older than 40 years [ n = 59 (85.5 percent)] and family history of breast cancer in first-degree relatives [ n = 47 (68.1 percent)] or family with a diagnosis before age 40 [ n = 49 (71.0 percent)] were the most common indications for preoperative imaging. Nineteen of the respondents (27.5 percent) routinely excise all macroscopic breast tissue, with 21 (30.4 percent) routinely leaving breast tissue. Fifty-one respondents (73.9 percent) routinely send specimens for pathologic analysis. There was no significant correlation between surgical volume or type of practice and odds of sending specimens for pathologic analysis. High patient costs and patient reluctance [ n = 27 (39.1 percent) and n = 24 (35.3 percent), respectively] were the most often cited barriers for sending specimens for pathologic analysis. Six respondents (8.7 percent) have found malignant or premalignant lesions in masculinizing breast specimens. CONCLUSIONS: Large variation was found among surgeons' perioperative management of chest masculinizing surgery patients regarding preoperative cancer screening, pathologic assessment of resected tissue, and postoperative cancer surveillance. Standardization of care and further studies are needed to document risk, incidence, and prevalence of breast cancer in the transmasculine population before and after surgery.

Quality of life improvement after chest wall masculinization in female-to-male transgender patients: A prospective study using the BREAST-Q and Body Uneasiness Test.

BACKGROUND: Chest reconstruction in many female-to-male (FTM) transgender individuals is an essential element of treatment for their gender dysphoria. In existing literature, there are very few longitudinal studies utilizing validated survey tools to evaluate patient reported outcomes surrounding this surgery. The purpose of our study is to prospectively evaluate patient reported satisfaction, improvement in body image, and quality of life following FTM chest wall reconstruction. METHODS: Our study was a prospective analysis of FTM patients who underwent chest reconstruction by a single surgeon (C.A.) between April 2015 and June 2016. The patients were surveyed preoperatively and 6 months after surgery utilizing the BREAST-Q breast reduction/mastectomy questionnaire and the Body Uneasiness Test (BUT-A). Analysis was performed on their self-reported demographic information, survey results, and chart review data. RESULTS: Of 87 eligible patients, 42 completed all surveys and could be linked to their chart data. From the BREAST-Q surveys, significant improvements were observed in the domains of breast satisfaction, psychosocial well-being, sexual satisfaction, and physical well-being. From the BUT-A surveys, we observed significant improvement in body image, avoidance, compulsive self-monitoring, and depersonalization. Groups with mental health conditions had poorer initial BUT-A scores and greater degree of improvement after surgery. CONCLUSIONS: As the prevalence of gender affirming surgery increases and as health policies are being developed in this area, the need for evidence-based studies surrounding specific interventions is essential. This study demonstrates significant improvement in a number of quality of life measurements in FTM patients after undergoing chest masculinization surgery.

The course of the frontal branch of the facial nerve in relation to fascial planes: an anatomic study.

BACKGROUND: Despite a wealth of literature describing the anatomy of the temporal region, controversy still exists over the depth of the frontal branch of the facial nerve as it travels over the zygomatic arch. It is commonly stated that the frontal branch travels within the superficial musculoaponeurotic system (SMAS) as it crosses the zygomatic arch. Clinically, however, it is apparent that the nerve runs at a deeper level as it crosses the arch, allowing for safe elevation and division of the SMAS to a point at or above the superior border of the zygomatic arch. The purpose of this study was to define the path of the frontal branches along fascial planes and to clarify the relationship of the fascial layers of the cheek and temporal region. METHODS: Eighteen fresh-frozen cadaver hemifaces were dissected in a layer-by-layer fashion to evaluate the relationship between the nerve and the fascial planes above and below the zygomatic arch. Histologic evaluation was performed on six hemifaces. RESULTS: In all dissections, the frontal branch traveled within the innominate fascia as it crossed the zygomatic arch into the temporal region. A fascial transition zone was identified in a region 1.5 to 3.0 cm above the zygomatic arch and 0.9 to 1.4 cm posterior to the lateral orbital rim, where the frontal branches crossed from the innominate fascia to run within the superficial temporal fascia. CONCLUSION: As the frontal branch crosses the zygomatic arch, it is within the innominate fascia, a plane deep to the SMAS and superficial temporal fascia.

Safely navigating around the facial nerve in three dimensions.

Although much literature discusses the anatomy and injury of the facial nerve branches, the fascial plane of the nerves, particularly where they transition from one plane to another, is rarely emphasized and information is often contradictory. This article describes in three-dimensional, accurate surgical terms where the facial nerve branches are located and how they can be protected during dissection above and below the superficial musculoaponeurotic system-platysma plane.
