Autologous Breast Reconstruction with Free Nipple–Areola Graft after Circumareolar (Skin Reducing) Mastectomy

Abstract

Introduction of skin-sparing mastectomy (SSM) led to a paradigm shift in breast reconstruction. Primary reconstructions have become the therapy of choice. At the same time, immediate autologous reconstructions are oncologically safe and aesthetically pleasing. Our preferred SSM incision is the circumareolar with removal of nipple and areola (NAC). Adjustment of the skin envelope is well accomplished in mild-to-moderate ptotic breasts. We describe our technique consisting of circumareolar incision in SSM, keeping the NAC as a free graft, and immediate autologous reconstruction and immediate free NAC grafting on the flap. Aesthetic indications are slight asymmetries, ptotic breasts, large breasts where the reconstructed breast will be smaller than the original breast and where a Wise pattern is not indicated. Oncologic indications are risk-reducing mastectomies and tumors close to the NAC where resection would compromise the vitality of the NAC. We evaluated the healing of the NAC and the NAC position with regard to the breast shape. From 2019–2022, 296 autologous flaps were used for breast reconstruction. In 36 flaps, this technique was applied. Eighteen flaps were bilateral (nine patients). In total, we performed 15 inner thigh flaps and 21 DIEP flaps. No flap or NAC loss occurred. There was no wound healing complication at the breast, and no adjuvant chemotherapy or radiation therapy needed to be postponed. The advantages of this technique are (1) scar reduction with only one periareolar scar on the breast, which is also well concealed; (2) oncological safety in relation to the nipple and optimal visibility of the mastectomy cavity, which allows a meticulous mastectomy, especially important in risk-reducing mastectomies; (3) generally, fewer wound healing problems, especially fewer than with Wise pattern incision; (4) primary adjustment of the skin envelope and positioning of the NAC are easier to perform than in a secondary procedure; and (5) that the NAC is spared, and no secondary reconstruction is necessary. Disadvantages are that (1) the NAC must heal as a free graft and (2) that the sensitivity of the NAC is lower than in pedicled NAC transposition.
