What are other risks of the surgery?

Problems which can occur include bleeding or hematoma formation, which can require a second operation for drainage of the collection of blood. This is more common in steroid users due to the high degree of vascularity of the chest wall. Infections are very unusual. The nipple sensation is usually altered after the operation, and in rare instances the nipple loses it's blood supply and dies. In this case, it has to be removed and replaced as a skin graft, but it doesn't look great when this is done. Depressions or contour irregularities can also occur.
