Different Surgical Modalities in the Management of Trigeminal Schwannomas

Abstract

chwannomas are well capsulated, slowly growing benign tumors. These tumors arise from schwann cells that wrap the peripheral or cranial nerves; hence, these tumors are basically peripheral nerve sheath tumors. Although trigeminal schwannoma is the second most common schwannoma after acoustic, it is a rare intracranial tumor. Trigeminal schwannoma accounts for 0.8–8% of all intracranial schwannomas and this corresponds to 0.07–0.36% of all intracranial neoplasm. Intracranial cystic schwannomas are not so common and barring the vestibular nerve; these tumors are rare. Intraorbital extension of trigeminal schwannoma is even rarer.
