Abstract

Several approaches to the cerebellopontine angle and internal auditory canal have been described for the removal of large acoustic tumors. Of these, the translabyrinthine removal of the large cerebellopontine angle tumors requires extensive removal of bones in order to manage the low-lying tegmen, the anterior sigmoid sinus, and the high jugular bulb. We removed 4 large cerebellopontine angle tumors by the translabyrinthine approach alone. All tumors were totally removed with acceptable facial nerve function. There was a case of CSF leak which was repaired at the revision surgery.
