In a robotic nipple-sparing mastectomy, the surgeon creates a small incision near the armpit or bra line, which helps to preserve the blood supply to the breast skin and the nipple. This reduces the risk of loss of the skin and/or nipple (tissue necrosis) as compared to traditional NSM, where the incisions are placed on the breast. The surgeon uses the robot to remotely dissect the breast tissue.
There are numerous benefits of performing nipple-sparing mastectomies robotically. The multi-level magnification feature allows the surgeon to explore the breast tissue in depth, rather than relying solely on the naked eye, which has considerable limitations. In addition, the use of the robot facilitates a far greater range of motion than the human wrist or hand is capable of, allowing the surgeon to access every part of the breast where tissue may be otherwise difficult to access. The aesthetic benefit of the smaller size and hidden location of the scar near the armpit, provides women with greater satisfaction and outcomes.
