title: Endoscopic surgery of cavernous sinus tumors originating from the extradura.
abstract: In the present study, we explored the effects of various endoscopic approaches in patients with cavernous sinus (CS) tumors. Five endoscopic approaches, including the endoscopic transseptal transsphenoidal approach, extended endoscopic transseptal transsphenoidal approach, extended transnasal transmaxillary approach, extranasal extended maxillary sinus approach, and endoscopic transnasal transpterygoid approach, were selected for the resection of CS tumors from 36 patients. Thirty gross total tumors and 6 subtotal tumors were removed. After a follow-up period of 6 months to 3 years, 30 patients were determined to be recurrence-free, and 2 patients had unchanged residual tumors. One patient with a recurrent pituitary adenoma underwent a second surgery, and 1 patient with chordoma died because of an intracavernous carotid artery rupture 18 months after the operation. Various endoscopic approaches tailored to the origin and extent of the CS tumor were proven efficacious for the maximal and precise removal of CS tumors while avoiding vital structures.
