Two-Stage Approach: Microsurgical and Endoscopic Endonasal Transpterygoid Approach for Giant Trigeminal Schwannoma Resection

A previously healthy 13-year-old patient presented with a 2-month history of numbness in the V2 territory and paresis of the third cranial nerve. MRI revealed a large, expansile lesion with well-defined borders and heterogeneous signal extending along the right cavernous sinus, right skull base foramina, into the pterygopalatine and infratemporal fossae. Due to the location and extent, a two-stage surgery was proposed: the first stage being transcranial and the second stage being endoscopic endonasal.
