Angiofibromas are histologically benign tumors, but clinically they often appear to be malignant because of their rich vascularity, so that massive bleeding may occur during surgery. Therefore, it is necessary to select a surgical technique with only slight bleeding and with a wide view enabling resection of the tumor en bloc.A 13-year-old male patient with a giant angiofibroma involving his nasopharynx, pterygopalatine fossa, and infratemporal fossa was treated here. We tried to resect the tumor en bloc without a skin incision. Le Fort I osteotomy was performed after embolization of the feeding artery of the tumor. The tumor was resected en bloc with little bleeding. There were no postoperative complications. We think that Le Fort I osteotomy is the most desirable technique for resecting angiofibromas with a wide view of the operative area.
