Individual surgical management of trigeminal schwannomas guided by an extended classification: a consecutive series of 96 clinical cases at a single institution.

ABSTRACT: Trigeminal schwannoma (TS) is a rare intracranial neurinoma that affects the multicompartmental skull base. In recent decades, advancements in skull-base neurosurgical techniques and endoscopic surgery have significantly improved outcomes for TS patients. In this study, we present our experience with surgical resection of TS using a further classification system. We conducted a retrospective analysis of the clinical, surgical, and follow-up data of 96 patients diagnosed with TS at our institution between March 2012 and June 2022. The tumors were classified based on the MPE classification, with Type M further divided into M1 and M2 subtypes according to the origin of the tumor and the patterns of cavernous sinus (CS) invasion. Type MP tumors were divided into M1P and M2P subtypes based on w
