Direct neurotization of free nipple grafts with cadaveric nerve grafts following mastectomy for gender affirming surgery.

BACKGROUND: Free nipple grafting makes sensory recovery challenging. Permanent decreased sensation to touch and temperature in skin-grafted skin is common. Direct neurotization of the nipple-areolar complex (NAC) graft has been described. However, quantitative data regarding degree of nipple reinnervation possible is unknown. This study aims to quantify and qualify sensation recovery following nerve coaptation to reinnervate the NAC. METHODS: Patients undergoing mastectomy for gender dysphoria from 2020 to 2022 were offered nerve allograft to restore nipple sensation. A lateral intercostal nerve was selected and coapted to allograft which was embedded beneath the nipple graft. Semmes Weinstein testing was used to assess nipple sensation. Assessments were made at visits <1 year and >1 year from surgery. Filaments used represented normal sensation, minor diminished sensation, diminished sensation, loss of protective sensation, and deep pressure sensation only. RESULTS: A total of 115 patients elected for direct neurotization. Semmes Weinstein testing was limited to 46 patients representing 46 encounters and 92 nipples in the <1 year group and 24 encounters and 48 nipples in the >1 year group. Of the 92 nipples in the <1 year group, 17 (18.5%) noted return of normal sensation and 37 (40.2%) noted minor diminished or diminished sensation, indicating nerve reinnervation. There were 38 (41%) nipples with loss of protective sensation or deep sensation only. There were 48 nipples included in the >1 year group. Of the 48 nipples, 4 (8.3%) noted normal sensation and 30 (62.5%) noted minor diminished or diminished sensation, indicating nerve reinnervation. For the remaining 14 nipples, 14 (29%) noted loss of protective sensation or deep sensation only. CONCLUSION: Sensory outcomes in NAC grafts used for reconstruction in patients undergoing double incision mastectomy remain poor. Sensation restoration beyond that expected from full thickness skin grafts can be achieved in the majority of patients with nerve allograft via direct neurotization.

COVID-19 Elective Surgery Shutdown and Operative Experience for Graduating Plastic Surgery Independent Residents.

INTRODUCTION: The initial wave of the COVID-19 pandemic led to a temporary shutdown of elective procedures. The purpose of this study is to evaluate how the elective surgery shutdown impacted case log numbers for graduating plastic surgery independent residents. METHODS: The Accreditation Council of Graduate Medical Education graduate self-reported case logs were retrospectively compiled for graduating independent track plastic surgery residents for the year before the pandemic (2019), 4 months into the pandemic (2020) and 16 months into the pandemic (2021). Procedures were grouped into resident review committee area and totals for each area were used for analysis. Average number of cases and standard deviations were compiled. Percent change was calculated comparing each year to the prepandemic baseline. Statistical significance was determined with Student t tests comparing average number of cases. Coefficients of variation were calculated to assess for changes in interprogram variation. Average case numbers were then compared with minimum case requirements necessary for graduation. RESULTS: The Accreditation Council of Graduate Medical Education graduation case log statistics were available for 238 independent residents. There were no statistically significant differences in average case number for graduating independent residents for total reconstructive breast, trunk, hand and upper extremity, or total reconstructive procedures between graduation years. The average case number of total lower extremity reconstruction increased from 2019 to 2020 (average = 83-97.4, P = 0.02). The average total number of breast aesthetic cases increased between all years (average = 92, 98, 114), with the average increase from 2019 to 2021 being statistically significant ( P = 0.02). Differences in head and neck aesthetic deformities and trunk and extremity deformities between years were not statistically significant. The average case number for all graduating plastic surgery independent residents exceeded the minimum case log requirements. CONCLUSIONS: The temporary hold on elective procedures during the pandemic decreased the opportunity for plastic surgery trainees to meet minimum case log requirements. Case log data for graduating plastic surgery independent residents demonstrate that despite the temporary suspension, the pandemic did not greatly impact the average resident case numbers.
