In nipple-sparing mastectomy, adequate perfusion to the nipple-areolar complex (NAC) during reconstruction is paramount to avoiding unwanted outcomes. Previous studies have suggested that periareolar incisions may result in higher rates of NAC complications. However, studies to date have not specifically investigated this in prepectoral reconstruction. The purpose of this study is to evaluate the impact of incision location on NAC complications in patients undergoing prepectoral breast reconstruction.MethodsWe performed a retrospective review of all patients who underwent immediate two-stage prepectoral breast reconstruction following nipple-sparing mastectomy between 2015 and 2018 at a single institution. We identified two types of incisions utilized: superior periareolar or inframammary fold (IMF). Patient demographics, comorbidities, and surgical details were compared between incision types, as were NAC complications.ResultsA total of 181 consecutive prepectoral breast reconstructions were included for analysis. A superior periareolar incision was used in 113 reconstructions (62%), and an IMF incision was used in 68 reconstructions (38%). There were 33 (18%) total NAC complications in our series. The periareolar incision group had a higher rate of any NAC complication (25% versus 7.4%; P < 0.01), as well as a higher rate of nipple necrosis requiring debridement (9.7% versus 1.5%; P = 0.03).ConclusionsIn patients undergoing immediate two-stage prepectoral breast reconstruction following nipple-sparing mastectomy, periareolar incisions are associated with an increased risk of NAC complications compared with IMF incisions. For patients who are candidates for either an IMF or periareolar incision, a periareolar incision should be avoided.
