Abstract 138: Breast Skin Reinnervation following Mastectomy

Abstract

The average BMI was 27.3 kg/m2 with 37 patients (27.4%) classified as obese. The prevalence of diabetes and tobacco history were each 5%. There were 28 patients (20.7%) who received neoadjuvant chemotherapy and 9 patients (6.7%) with prior breast irradiation. Nipple sparing mastectomies were performed in 73 patients (54%) and 108 patients (80%) underwent bilateral reconstruction. Immediate tissue expander insertion after mastectomy was performed in 111 patients (82%). Complete anterior coverage of the tissue expander with acellular dermal matrix (ADM) was performed in 86% of the immediate reconstruction cases and ADM was used in 25% of the delayed reconstruction cases. There were 33 patients (24%) who received postoperative oral antibiotics for greater than 24 hours following the procedure. The overall rate of complications following stage 1 reconstruction was 23%, with 6 patients experiencing multiple complications. Surgical site infection (23 patients, 17%) and flap and/or nipple necrosis (14 patients, 10%) were the most common complications. There was 1 complication of incision dehiscence. Multivariate analysis demonstrated that both obesity and immediate reconstruction were associated with increased risk of surgical site infection (OR 4.7, p= 0.006 and OR 12.4, p=0.028), though neither were associated with flap necrosis.
