Abstract
Depressed scars may develop from subcutaneous fat damage after facial trauma. For cases without visible scars on the skin surface, a non-incisional approach is preferred. We treated a depressed scar on the mandible with string-shaped dermal fat grafts. Using an 18-gauge needle, the scar was released from the underlying tissue. A dermal fat graft, harvested from the postauricular area and cut into strings, was inserted through the needle hole. The depression improved with satisfactory aesthetic results, requiring no special equipment and avoiding new visible scars on the exposed areas of the face.
