Delayed two-stage nipple sparing mastectomy and simultaneous expander-to-implant reconstruction of the large and ptotic breast.

BACKGROUND

Large and ptotic breasts are considered an anatomical contraindication for nipple sparing mastectomy (NSM). Necrosis rates can be as high as 76%. The authors examined whether targeted preshaping mastopexy/reduction combined with simultaneous two-stage preshaping of the implant pocket prepares for an uneventful implant reconstruction.

METHODS

Macromastia and ptosis patients opting for risk-reducing NSM or having a peripherally localized carcinoma in situ, were offered a two-stage mastopexy/reduction simultaneously with preshaping of the implant pocket by subpectoral expansion. Only the inferior pedicle bearing the nipple-areola complex (NAC), remained. A delayed secondary NSM and tissue expander-to-implant reconstruction was scheduled 3 months later. The use of an acellular dermal matrix (ADM) was not necessary because the capsule around the expander created a hammock supporting the definite prosthesis. Follow up was at 2 weeks, 3 months, and 6 months.

RESULTS

Forty-one procedures were performed in 24 patients. The mean age was 45±12.08 years (range, 22 to 72 years). Patients' mean body mass index (BMI) was 26.79 kg/m2 (range, 19 to 35 kg/m2). One patient had diabetes and two smoked. One transient epidermolysis of the NAC occurred in each stage. No NAC or skin necrosis occurred; no implant had to be removed.

CONCLUSIONS

A two-stage mastopexy/reduction, simultaneously with preshaping of the implant pocket by tissue expansion and followed by a 3-month delayed secondary NSM with tissue expander-to-implant reconstruction is a safe technique in large ptotic breasts.
