Endoscopic Resection of Pterygopalatine Fossa and Infratemporal Fossa Malignancies

Abstract

The endoscopic resection of pterygopalatine and infratemporal fossa malignancies allows excellent visualization and manipulation of tissues in an anatomically complex area compared with open approaches. With less approach morbidity, endoscopic endonasal surgery allows an easier recovery and earlier transition to adjuvant radiotherapy. The endoscopic approach is minimal access but rarely minimally invasive. Surgeons should not hesitate to gain wide surgical exposure of the pterygopalatine, infratemporal fossa, and petrocavernous carotid artery to ensure comfortable maneuverability and easy visualization of the tumor and its normal tissue margins. This method maximizes the chances of complete resection and effective postoperative surveillance.
