Transaxillary Nipple-Sparing Mastectomy and Direct-to-Implant Breast Reconstruction Using a Simplified Endoscopic Approach: Indications, Cosmetic Outcomes and Technical Refinements

Background: The increasing demand for further aesthetic outcome improvement in implant-based breast reconstruction after nipple-sparing mastectomy (NSM) leads to major novelties, including endoscopic and robotic NSM with the aim to limit scar visibility. In this paper, we report our experience with a novel and simplified surgical approach—single-axillary-incision non-endoscopic NSM and node surgery followed by an endoscopic DTI breast reconstruction—by focusing on reconstructive indications, technical refinements and aesthetic outcomes. Methods: Between June 2016 and October 2019, 14 women underwent this novel technique using definitive anatomical silicone gel filled, totaling 20 breasts. Reconstructive evaluation methods were clinically and photography-based assessment. Breast-Q has been used to quantify patient satisfaction. Feasibility and safety data are also provided. Results: The average follow-up time was 11 months (range 3–42 months). No local–regional recurrence occurred during follow-up. Median operation time was 340 min; mean hospital stay was 4.1 days. The average mastectomy specimen weight was on average 139 g (ranging from 98 to 182 g). The average implant volume for the reconstructed side was 306 cc (ranging from 165 to 550 cc). Patients’ satisfaction was high to very high. Conclusion: Authors’ experience suggests that non-endoscopic transaxillary NSM, node surgery and endoscopic direct-to-implant breast reconstruction is a valid, oncological safe, aesthetically sound scarless option in breast cancer patients with small to moderate breast size. It should represent the incision of choice in patient with previous breast surgery with scars that may compromise flap/NAC vascularity using traditional NSM incisions.
