BackgroundImplant-based reconstruction is currently the most common postmastectomy breast reconstruction modality with over 86,000 procedures performed in 2017. Although various methods for reconstruction techniques have been described, partial subpectoral implant placement with or without acellular dermal matrix coverage remains the most popular approach. Recently, prepectoral implant placement has gained increased recognition as a method that avoids some of the potential morbidities of submuscular implant placement. Currently, few studies have examined the outcomes of performing this approach. The purpose of this study was to evaluate and compare the outcomes of prepectoral and subpectoral direct to implant (DTI) immediate breast reconstruction.MethodsData from a prospective cohort of consecutive patients undergoing prepectoral DTI immediate breast reconstructions at our institution from February 2016 to November 2017 were collected. The incidence of complications such as mastectomy skin flap necrosis, seroma, hematoma, infection, implant loss, and unexpected reoperation were recorded and compared with a cohort of consecutive patients who underwent subpectoral DTI immediate breast reconstruction from May 2014 to July 2015.ResultsOne hundred twelve prepectoral DTI immediate breast reconstructions were performed on 62 patients. Four breasts (4.4%) were diagnosed with infection. There were 8 breasts (7.1%) that suffered from mastectomy skin flap necrosis (5 partial thickness necrosis, 3 full thickness necrosis). There was 1 implant loss related to full thickness necrosis that required salvage with autologous tissue reconstruction. Prepectoral breast reconstruction had less esthetic revisions and comparable complications when compared with the historical subpectoral cohort.ConclusionsWhen compared with the subpectoral DTI approach, prepectoral DTI breast reconstruction grants favorable complication rates and improved esthetic outcomes. Prepectoral DTI breast reconstruction is a safe modality that should be considered in any patient who is a candidate for immediate breast reconstruction.
