Immediate reconstruction using a scalp-forehead flap for the entire upper lip defect with the application of lyophilized porcine skin to surgical wounds. A case report of a malignant melanoma in the upper lip and oral mucosa

A rare extensive malignant melanoma involving the upper lip and maxillary alveolar mucosa was removed by en bloc resection after chemotherapy and radiotherapy. Simultaneous immediate reconstruction of the entire upper lip defect was carried out with a bitemporal pedicle flap which included the scalp and forehead after applying lyophilized porcine skin to the wound where the alveolar bone had been resected, and the bilateral scalp-forehead and thigh donor sites. A partial denture was inserted six months postoperatively. Now, one and a half years after operation, the patient is quite satisfied with his cosmetic appearance and masticatory recovery.
