Contralateral Subfrontal Supraorbital Approach for Microsurgical Resection of Optic Canal Meningioma

Meningiomas are mostly benign tumors of the central nervous system. Recurrence can be seen in clinoidal meningiomas especially extending into optic canal. We present a patient with a history of left clinoidal meningioma excision via pterional approach and recurrence purely in left optic canal. Optic canal drilling is necessary for complete removal of these type of tumors. Contralateral subfrontal approach with an eyebrow incision and a keyhole supraorbital craniotomy was used for this patient. Contralateral viewing of the surgical area provided direct angles and created better workspace for the surgeon. Total excision was achieved with no additional neurological deficits in the postoperative period. This approach can be used with its wide exposure of surgical site, potential space usage without need of retraction and better postoperative scar healing.
