Background The purpose of this study is to evaluate how prior breast augmentation impacts rates of complications and risk for reoperation after mastectomy with concurrent breast reconstruction. Methods Patients undergoing nipple-sparing, skin-sparing, or simple mastectomy with implant-based reconstruction from 2008 to 2018 were identified in a prospective database. Postoperative complications and reoperations were then analyzed comparing patients with prior augmentation to patients without history of previous breast surgery. Results A total of 468 patients were identified with a median follow-up of 4 years. Of these, 72 had prior augmentation mammoplasty. These patients underwent nipple-sparing (52, 72%), skin-sparing (15, 21%), or simple (5, 7%) mastectomy with immediate direct-to-implant (46, 61%) or tissue expander (26, 35%) reconstruction. On univariate analysis, this cohort had a lower body mass index (23.3 vs 25.3, P = 0.003), a higher rate of nipple-sparing mastectomy (72% vs 54%, P = 0.01), and a higher prevalence of stage I disease (44% vs 33%, P = 0.04). Differences in age, comorbidities, reconstructive techniques, tumor size, and neoadjuvant/adjuvant therapies were not significant. Overall complication rate between patients with or without prior augmentation did not significantly differ (51% vs 50%, P = 0.83); no significant differences in rates of surgical site infection, hematoma, mastectomy skin flap/wound necrosis, nipple complications, implant loss, or capsular contracture were found. Analysis of reoperations between patients with and without prior augmentation revealed no significant differences in average number of subsequent planned, unplanned, or total reoperations. On multivariate analysis, prior breast augmentation was found to be associated with significantly increased risk for undergoing ≥1 unplanned reoperation (odds ratio, 2.28; 95% confidence interval, 1.28-4.05, P = 0.005). Conclusions Prior augmentation mammoplasty does not significantly affect rates of postoperative complications after mastectomy with concurrent reconstruction. Although prior augmentation does not affect number of subsequent reoperations on average, it does increase the risk of experiencing 1 or more unplanned reoperation after mastectomy with reconstruction.
