Outcomes Using Two Unique Methods of Immediate Implant-Based Breast Reconstruction After Nipple-Sparing Mastectomy in Ptotic Patients

ObjectiveAfter nipple-sparing mastectomy (NSM) and immediate implant-based reconstruction, patients with significant ptosis are at increased risk for nipple-areolar complex (NAC) necrosis. Attempts to salvage the nipple using inferior dermal pedicles have yielded unsatisfactory results. This study aims to evaluate complications using 2 unique methods of breast reconstruction using either a Wise incision with dermal infolding or batwing incision after NSM.Materials and MethodsA retrospective chart review was conducted on all patients who underwent NSM and immediate implant reconstruction using the methods described by a single surgeon between 2016 and 2022. Outcomes were assessed by comparing average complications rates.ResultSeventy-three reconstructions were performed after NSM in patients with ptosis. Sixteen reconstructions used a prior technique, Wise pattern with inferior dermal flap. Thirty reconstructions used the Wise incision with dermal infolding, while 27 other reconstructions used a batwing incision. For the Wise with inferior dermal flap technique, NAC necrosis occurred in 43.8%. In the cases in which the newer techniques were used, NAC necrosis occurred in 11.1% in the batwing group and 10% in the dermal infolding group. Other complications measured were within acceptable percentiles between both groups. Aesthetic outcomes were acceptable for most of the cases involving NAC necrosis.ConclusionsA batwing pattern incision or a Wise pattern with a broad, infolded dermal pedicle is a more effective method of immediate reconstruction after NSM in patients with ptosis according to these findings. Nipple-areolar complex necrosis continues to be a major complication that is important to discuss with patients. However, these methods offer patients with ptosis the benefit of preserving a native NAC while allowing for simultaneous skin reduction during an immediate reconstruction.
