Abstract

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.
