Translabyrinthine removal of cerebellopontine angle meningiomas.

The authors report two cases of the microscopic total removal of meningiomas in the region of the cerebellopontine angle using the translabyrinthine approach. Although both tumors were larger than 4 cm, the only resulting neurological deficit was ipsilateral hearing loss. The translabyrinthine approach may be an alternative measure in dealing with these difficult lesions.
