Endoscopic Approach to the Trigeminal Schwannoma of the Pterygopalatine Fossa

Abstract

Schwannomas develop from Schwann cells surrounding neural tissue and compose 8% of all intracranial tumors.Trigeminal schwannoma is rare, but it occurs secondly after vestibular schwannoma. These tumors may originatefrom any part, between the root and the distal extracranial branches of the trigeminal nerve. Therefore, different signsand symptoms occur depending on the actual size and site of origin of the tumor. In this article, it is aimed to discusstrigeminal schwannoma located in the pterygopalatine fossa in context of diagnosis and treatment methods.
