title: [Endoscopic resection of sphenoid sinus tumor compressing the optic nerve].
abstract: Thanks to recent technical refinements the orbital apex can be explored endoscopically and this approach is used for tumor biopsy in some specialized centers. Nevertheless, only a few instances of total tumor resection have been reported to date. In this contribution we report a case of a 64 years old woman in whom we used neuronavigated endoscopy and intraoperative Doppler sonography, for total removal of a tumor located in the sphenoid sinus and invading the orbital apex. The visual acuity improved from 5/16 to 5/6 and HP diagnosis was cystis spuria.
