Typically we ask that you remove the metallic rings/piercings fron the surgical site as the cautery might cause burns. If the piercings are very new, a plastics spacer can be used as it doesn't conduct the electrical current. The piercings can be replaced immediately post operatively
Metal nipple rings need to be removed before surgery because the cautery that is used to stop bleeding as the tissues is cut, can cause the metal to heat up and cause a burn.
