Hidden scar breast reconstruction: endoscopic technique spares muscle
NCT ID NCT03838549
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new surgical method for immediate breast reconstruction after preventive mastectomy in women at high genetic risk for breast cancer. Instead of a scar on the breast, surgeons used a single-port endoscope through the armpit to place the implant under the skin, without cutting the chest muscle. The goal was to reduce complications and improve cosmetic results. The study included 20 women with small to medium breast size and minimal sagging.
