Nipple-Sparing Mastectomy

Posted Mar 06 2013 8:14am
Nipple-sparing mastectomy in conjunction with immediate breast reconstruction is becoming more and more popular so I thought a blog post about it was in order...

A nipple-sparing mastectomy preserves the nipple,  areola and all the surrounding breast skin which is then used for the breast reconstruction. Unlike the traditional "modified radical mastectomy", nipple-sparing mastectomy only removes the breast tissue ("parenchyma") under the skin.

Studies show that nipple-sparing mastectomy provides the same level of surgical treatment as a modified radical mastectomy in appropriate candidates. Preserving the nipple-areola complex adds to the quality of the reconstruction making the results even more "natural". It also means the patient avoids having to go through the additional steps of nipple reconstruction and tattooing.

Nipple-sparing mastectomy is an option for many patients with a small cancer located several centimeters away from the nipple-areola complex. Patients with ductal carcinoma in situ (DCIS) can also be candidates, again depending on the location and distance from the nipple-areola.

During the surgery, a biopsy ("frozen section") is taken from behind the nipple-areola complex and sent to pathology to make sure there is no cancer under the nipple or areola. If this biopsy is negative then the area can be preserved. If it is positive for cancer cells, the nipple and areola are obviously removed.

Patients at high risk of breast cancer (eg BRCA+, strong family history, Cowden's syndrome) choosing to undergo prophylactic (preventive) mastectomy and immediate breast reconstruction are the best candidates.

Patients who do not need a signficant breast lift will have the best cosmetic results.

Nipple sensation is usually significantly reduced. Sometimes feeling is lost completely. Even in cases where some nipple-areola sensation is maintained, it is very unlikely the feeling will be as Mother Nature provided.

The underside of the nipple and areola is "shaved down" to remove as much of the breast tissue as possible. This can sometimes compromise the blood supply to the tissue which can then cause healing problems. If the blood supply is damaged too much by the mastectomy, part or all of the nipple-areola can die. Thankfully this is uncommon.

At PRMA we check the blood flow intra-operatively to ensure the nipple-areola will survive. In the unlikely event that the nipple-areola cannot be saved, it is removed to prevent wound healing complications and a new nipple and areola are reconstructed at a later time.

This depends on the size and shape of the breast, whether a small "lift" is needed, patient preference and surgeon preference. Scars can be placed around part of the areola and extended outwards or downwards, or completely away from the areola at the breast crease ("inframmamary fold incision").


I hope this info helps!
