Salvage of Extensive Skin Graft Necrosis After Auricle Reconstruction by Using Modified Nagata Method.

ABSTRACT

Extensive skin graft necrosis after auricle reconstruction surgery is a thorny problem for plastic surgeons. Four unilateral microtia patients were enrolled for extensive skin graft necrosis after ear elevation surgery. Early debridement and daily dressing changes were important for preoperative preparation. Surgical treatments involved local flaps and secondary split-thickness skin graft. After 3 to 12 months of follow-up, clear surface structures and obvious auricular sulcus were shown in all 4 patients. No cartilage exposure, skin necrosis, healing impairment, or other complications were found. We attribute the cause of extensive skin graft necrosis to subcutaneous hematoma. Local skin flaps and split-thickness skin grafting can be effective treatments for such situations. The use of temporoparietal fascial flap is unnecessary when poor graft survival is caused by subcutaneous hematoma.
