Breast reconstruction with nipple surgery is usually the final phase of breast reconstruction. It is done to make the reconstructed breast look more like the original breast. Typically, a small incision is made at the site where the nipple will be made. The skin is formed into a nipple shape and stitches are used to secure the form. Some surgeons insert a core of dermal matrix product into the reconstructed nipple so it doesn't flatten out too much. Once the nipple is sewn into place, a nipple shield (a protective covering shaped like a tiny hat with a wide flat brim) is filled with antibacterial ointment and taped over the reconstructed nipple to protect it.
