Because the patients and their family members refused to perform the conventional different area skin grafting with greater trauma, they chose local anesthesia to perform the wound edge microgranular skin grafting. Such wounds routinely require surgery such as abdominal embedment, skin grafting or skin flap transfer to avoid aggravation of infection, heal the wound, and restore the function of the affected area.
