Staging Nipple-Sparing Mastectomy can Decrease the Risk of Complications
Nipple-sparing mastectomy (NSM) is the latest evolution in mastectomy technique. The procedure preserves the entire skin envelope and nipple-areola. Only the underlying breast tissue is removed. Nipple-sparing mastectomy significantly improves cosmetic results when combined with immediate breast reconstruction, and is oncologically safe when performed in appropriate candidates. It can also improve the return of sensation in some patients.
However, certain factors such as large breast size and a low nipple location can increase the risk of complications such as partial or even complete necrosis of the nipple and areola. There is some good news though for patients choosing NSM to decrease their risk of getting breast cancer (“prophylactic” or “risk-reducing” NSM)… “Staged” surgery with a breast reduction performed at least three months before the NSM significantly decreases these complications in patients with larger breasts.
According to a study published in Plastic and Reconstructive Surgery that compared the staged approach with the traditional all-in-one surgery, staged surgery patients experienced no major skin or nipple-areola necrosis. However, patients who did not reduce their breast size via a breast reduction before having their NSM and immediate reconstruction experienced major necrosis 22% of the time.
The staged approach allows surgeons to reduce the patient’s overall breast size, remove excess skin, and reposition the nipple-areola before the definitive NSM and reconstruction. By decreasing the overall size of the breast and relocating the nipple-areola to a more favorable position ahead of time, the demands on the blood supply at the time of the NSM are significantly reduced. This in turn decreases the risk of complications.
Staging does add an addition surgery and cost, along with a longer overall recovery period, but should be considered in patients who may otherwise not be good candidates for risk-reducing NSM due to large breast size or a low-lying nipple-areola. Patients with a cancer diagnosis are usually not candidates for this staged approach due to the delay it adds to treatment of the cancer.
