Background: Prepectoral prosthetic breast reconstruction is gaining popularity, offering muscle preservation and outcomes similar to subpectoral implant placement in small or moderate size breasts. This study compares the complications of prepectoral and subpectoral immediate prosthetic breast reconstructions following skin reduction mastectomy in large and ptotic breasts. Methods: All consecutive patients who underwent immediate tissue expander-based reconstruction following Wise pattern skin reduction mastectomy from November 2011 through August 2017 by a single surgeon were reviewed. The collected data included patient demographics and complications (eg, skin necrosis, hematoma, infection, seroma, implant loss, capsular contracture). Results: A total of 54 patients underwent 87 immediate breast reconstructions including 45 subpectoral and 42 prepectoral tissue expander placements. The subpectoral patients had greater body mass indexes (32.5 +/- 6.6 versus 29.9 +/- 5.4, P = 0.026), higher initial (518 +/- 168 ml versus 288 +/- 140 ml, P < 0.001) and final (694 +/- 123 ml versus 585 +/- 122 ml, P = 0.014) implant volumes, more skin flap necrosis (40.0% versus 16.7%, P = 0.044) and infections (37.8% versus 11.9%, P = 0.01) than their prepectoral counterparts, whereas seromas were more common in the prepectoral group (4.4% versus 26.2%, P = 0.015). The overall complication rate, although higher in the subpectoral group compared with the prepectoral group, was not significantly different (62.2% versus 40.5%, P = 0.072). Conclusions: Prepectoral tissue expander placement after skin reduction mastectomy is an appealing reconstructive option in patients with large and ptotic breasts. Prosthetic reconstruction following Wise-pattern skin reduction mastectomy is invariably associated with high complication rates irrespective of the plane of implant placement. Greater emphasis should be placed on patient counseling and complication prevention in this challenging patient population.
