A case of partial radionecrosis of sphenoid and temporal bone was reported. The patient had received combined therapy of surgery, radiotherapy and chemotherapy for his left maxillary sinus carcinoma.<BR>After the combined therapy, a painful inflammation appeared due to necrosis of the affected bone and soft tissues. Resection of the left ascending ramus of the mandible was also performed because of persistent tumor mass at the left infratemporal fossa. Epithelization of the exposed bone following left temporal region surgery did not occur but progressiveosteonecrosis with infection led to breakdown of the outer tissues, and his left zygomatic arch and a part of the sphenotemporal suture were exposed.<BR>The possibility of the occurrence of intracranial complication was also considered, andresection of the nectrotic bone and reconstruction using sternocleidomastoid myocutaneous flap were performed.
