The Middle Fossa Approach for Removal of Small Acoustic Tumors

Abstract

We have described a technique for the removal of small acoustic tumors confined to, or slightly protruding into, the posterior fossa. The case reports of 5 patients have been presented. Total removal of an acoustic tumor was accomplished in all of these patients. The facial nerve was preserved in 5 of the patients and hearing was saved in 4 patients. The study emphasizes the significance of the complaints of vertigo, unsteadiness, tinnitus and mild hearing loss. Patients with these symptoms, either singly or in combination, should receive thorough otologic and radiologic evaluation if they are to receive the maximum benefit from modern neuro-otologic surgery.
