Three Pedicles-Based Nipple-Sparing Skin-Reducing Mastectomy (TP-NSSRM) combined with Pre-Pectoral Implant-Based Breast Reconstruction.

Abstract

Nipple-sparing mastectomy (NSM) and immediate breast reconstruction have demonstrated positive aesthetic outcomes and high patient satisfaction. However, challenges arise when performing NSM on patients with large and ptotic breasts due to the higher risk of nipple-areolar complex (NAC) necrosis. This study proposes a new technique: the three pedicles-based nipple-sparing skin-reducing mastectomy (TP-NSSRM), combined with direct-to-implant (DTI) breast reconstruction, aimed at reducing complications. A prospective study was conducted from November 2021 to April 2022, enrolling patients with large and drooping breasts requiring mastectomy for breast cancer treatment or risk reduction. Patient selection criteria included a sternal notch to nipple distance of ≥ 23 cm, Grade 3 ptosis, and eligibility for immediate prepectoral DTI breast reconstruction. Patient satisfaction was assessed using BREAST-Q modules. Seventy-two TP-NSSRM procedures combined with immediate DTI-based breast reconstruction were performed on a total of 45 patients. High patient satisfaction was observed, and statistically significant improvements were noted in postoperative BREAST-Q scores (p=0.001). The complication rate was low, and preservation of the nipple-areolar complex was achieved in all cases. The TP-NSSRM technique offers a potential solution for patients with large and drooping breasts undergoing NSM. It aims to minimize complications and achieve satisfactory outcomes. This study demonstrates favorable results in terms of patient satisfaction and quality of life. Further research and long-term follow-up are necessary to validate these findings and evaluate the long-term outcomes of this technique.
