title: Hearing preservation in patients with acoustic neuromas via the middle fossa approach.
abstract: Twenty patients with acoustic neuromas were operated on in an attempt to preserve hearing. These patients were selected from a series of approximately 300 patients seen from May 1975 to March 1979. All patients were operated on via the middle fossa approach. Hearing was preserved in approximately 35% of the patients. Preoperative and postoperative audiograms were performed on all patients. Tumor size ranged from 5 to 15 mm. These current cases are compared and added to our previous series of 17 cases (10 with hearing preserved) from a series of 500 acoustic neuromas reported elsewhere. Selection of patients, audiogram results, details of the middle fossa procedure, and work by other investigators are discussed.
