[Endoscopic resection of sphenoid sinus tumor compressing the optic nerve]. / Endoskopowe usuniecie guza zatoki klinowej wchodzacego do szczytu oczodolu.

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.
