Endoscopic transoral and transmaxillary excision of the infratemporal fossa hemangioma.

Hemangiomas in the infratemporal fossa (ITF) are extremely rare benign vascular tumors. For many tumors of the ITF, with the exception of some small hemangiomas, a lateral facial approach has often been required. Recently, however, there have been some reports that minimally invasive endoscopic surgery can be used in the ITF; this would reduce the risk of surgical complications. To date, there has been no report of a hemangioma of the ITF exceeding 6 cm being resected by the endoscopic approach without facial incisions. Here, however, we report two cases of ITF hemangiomas that were completely extracted endoscopically, using a transmaxillary and transoral approach, without facial incisions or surgical complications.
