Abstract

BACKGROUND:

Nipple-sparing mastectomy performed via an inframammary fold incision with implant-based reconstruction is an oncologically safe procedure that provides excellent cosmesis.

OBJECTIVES:

The authors report their experience with conservative treatment of postoperative nipple-areolar complex (NAC) ischemia and an analysis of risk factors for NAC ischemia and conservative treatment failure.

METHODS:

A retrospective chart review was conducted of 318 nipple-sparing mastectomies performed through inframammary fold incisions with implant-based reconstruction between July 2006 and October 2012. NAC dressings consisted of topical nitroglycerin, external warming for 24 hours, antibacterial petrolatum gauze, and a loose bra for 1 week. Patients were monitored for NAC ischemia as the primary endpoint. NAC ischemia was treated with bacitracin ointment. In cases of full-thickness ischemia, expanders were also partially deflated.

RESULTS:

Partial- and full-thickness NAC ischemia occurred in 44 (13.8%) and 21 (6.6%) cases, respectively. All partial- and 17 full-thickness cases resolved with conservative treatment. Of these, 7 partial- and 2 full-thickness cases suffered residual depigmentation. Four full-thickness cases required operative debridement. Factors associated with NAC ischemia included increasing age (P = .035), higher body mass index (P = .0009), greater breast volume (P = .0023), and diabetes (P = .0046). Factors associated with conservative treatment failure included increasing age (P < .0001), higher body mass index (P = .014), greater breast volume (P = .020), smoking (P = .0449), acellular dermal matrix use (P < .0001), and single-stage reconstruction (P = .0090).

CONCLUSIONS:

Postoperative NAC ischemia can be effectively managed conservatively to preserve cosmesis and implant viability. Knowledge of risk factors for NAC ischemia and conservative treatment failure may improve future patient counseling and outcomes.
