BACKGROUND: Prepectoral implant-based reconstruction reemerged as a viable approach following recent advances in reconstructive techniques and technology. To achieve successful outcomes, careful patient selection is critical. Obesity increases the risk of complications and has been suggested as a relative contraindication for prepectoral breast reconstruction. METHODS: Retrospective chart review of patients who underwent immediate two-stage implant-based reconstruction at the authors' institution was performed. Only women having a body mass index of 30 kg/m or greater were included. Patient demographics, operative details, and surgical outcomes of prepectoral and subpectoral reconstruction were compared. RESULTS: One hundred ten patients (189 breasts) who underwent prepectoral and 83 (147 breasts) who underwent subpectoral reconstruction were included. Complications were comparable between the two groups. Twelve devices (6.4 percent), including implants and tissue expanders, required explantation in the prepectoral group, and 12 devices (8.2 percent) required explantation in the subpectoral group (p =0.522). Final implant-based reconstruction was achieved in 180 breasts (95.2 percent) in the prepectoral group and 141 breasts (95.9 percent) in the subpectoral group. Regardless of type of reconstruction (prepectoral or subpectoral), for each point increase in body mass index, the odds of complications and device explantation increased by 3.4 percent and 8.6 percent, respectively; and the optimal cutoff to predict higher complications and explantation rates was a body mass index of 34.8 kg/m and 34.1 kg/m, respectively. CONCLUSIONS: Obesity increases complications and failure rates in a positive correlation; however, complications and final reconstruction rates are comparable between the prepectoral and subpectoral groups. The authors believe that obesity should not be a contraindication for prepectoral breast reconstruction but that care should be taken in patients with a body mass index above 35 kg/m. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
