The accuracy of intraoperative subareolar frozen section in nipple-sparing mastectomies.

Abstract

Intraoperative subareolar frozen section is a specific but nonsensitive test. It is useful in nipple-sparing mastectomy because in 10% of cases a positive result allows immediate nipple and areolar excision. Its low sensitivity and negative predictive value means that 15% of patients will need a subsequent nipple and areolar excision. Eighty-five percent of patients can, however, have a single-stage excision.
