This is a prospective registry trial to determine the outcomes of single port robot-assisted nipple sparing mastectomy (SPrNSM) utilitzing the SP da Vinci surgical system.

Robotic assisted nipple sparing mastectomies with multi-port robots, like the Da Vinci Xi, have been described previously but pose significant hurdles due to the small area like the breast. The Single-Port da Vinci SP (Intuitive Surgical), which was designed for application to small cavity surgery, may be more appropriately suited for this procedure. This is a prospective registry trial to study the outcomes of performing a single-port robot-assisted nipple sparing mastectomy.

Subjects who undergo rNSM and bilateral breast reconstruction of the affected breast via single site small hidden axillary scar technique will be offered participation in the prospective registry trial at their pre-operative visit in the UT Southwestern Breast Clinic. The patient will then be seen at their regularly scheduled clinic appointments at 2 weeks, 1 month, 6 months, and 1 year post operatively at both Breast and Plastics and Reconstructive Surgery (PRS) departments. Outcomes will be tracked in a prospectively kept electronic registry.

Inclusion Criteria:

1. Subjects age >= 18 years who undergo robotic nipple sparing mastectomy and breast reconstruction with prosthesis at UTSW

Exclusion Criteria:

1. Subjects who are <18 years of age
2. Subjects who do not undergo robotic nipple sparing mastectomy and breast reconstruction with prosthesis at UTSW

Adult women who undergo robotic nipple sparing mastectomy (rNSM) with reconstruction.

The study share data of individual participants.
