If complications occur, they usually delay the healing process. In rare cases, another surgery is needed to fix a potential complication. Skin necrosis is one of the complications that may require another procedure as the dead skin must be replaced by a skin graft. Although necrosis is extremely rare, smokers have an increased risk to develop skin necrosis. Stopping nicotine use and smoking several weeks before and several weeks after surgery cleans the body and improves the chance of an uneventful recovery.
