Endoscopic Transvestibular Transmandibular Approach for Trigeminal Schwannoma in Infratemporal Fossa and Parapharyngeal Space

Schwannomas located in the ITF and PPS are rare benign neoplasms. They are usually detected late after considerable signs and symptoms appear. Preoperative planning is beneficial to individual surgical approach selection. Total surgical excision following careful evaluation of preoperative computed tomography and magnetic resonance images is the treatment of choice. Recurrence is rare after complete excision.
