AbstractNipple-sparing mastectomy (NSM) with immediate implant-based reconstruction has better esthetic outcomes and improved patient satisfaction, in addition to being oncologically safe. A known complication of NSM is skin flap necrosis. The use of tumescence and sharp dissection may decrease this complication compared to the standard NSM technique using electrocautery. This is a retrospective review of patients who underwent a NSM between 2014 and 2017 at a regional cancer center. Tumescence with sharp dissection was compared to electrocautery. The primary outcome was skin flap necrosis. The secondary outcomes were operative time and management of the complication. A total of 62 patients underwent a NSM with 116 breasts being operated on. Full-thickness necrosis occurred more frequently in the standard electrocautery group (12.8%) compared to the tumescence and sharp dissection group (1.3%; P = 0.02). Partial-thickness necrosis also occurred more frequently in the standard group (33.3%) compared to the sharp dissection group (13.0%; P = 0.01). The operative time was significantly shorter in the sharp dissection group with the mean (SD) time being 183.5 (48.9) minutes compared to the standard electrocautery group at 202.9 (33.8) minutes (P = 0.03). NSM using tumescence and sharp dissection have a lower rate of the complications of partial- and full-thickness necrosis. Shorter operative time was also seen with the tumescent technique.© 2019 Wiley Periodicals, Inc.
