Extracranial Trigeminal Schwannoma Involving the Inferior Alveolar Canal

Although trigeminal schwannomas (TS) are rare tumors that may involve any parts of the trigeminal nerve, most of these tumors are located in the intracranium. Extracranial TS are extremely rare. Management of extracranial TS is challenging because of the anatomic complexity around the tumor. Therefore, thorough surgical planning should be required preoperatively for complete tumor removal with the least morbidities. We presented a 64-year-old man with a trigeminal mandibular schwannoma in the left infratemporal, parapharyngeal, pterygomandibular space and inferior alveolar canal of mandible.
