Endoscopic transnasal resection of JNA's have become popular around the country. In this video we present the endoscopic approach for a large JNA extending to the anterior skull base. The neoplasm underwent preoperative embolization. A step by step approach, cauterizing all feeding vessels is described. At the end of the video, careful analysis of the pterygomaxillary space and adjacent inferior orbital fissure reveals small tumor fragments.
