[Results of 100 consecutively operated patients with acoustic neuroma].
The results from 100 patients with 103 acoustic neurinomas who were operated on between February 1979 and April 1992 are presented. All patients were placed in the half-sitting position and operated on by the same surgeon using the suboccipital-trans-meatal approach. Postoperative facial nerve function was good in 56%, moderate in 20% and poor in 24% of our patients. Preservation of useful hearing was achieved in 21%: the smaller the tumor, the better the functional result. However, the early symptoms of acoustic neuromas (tinnitus, dizziness, feeling of unsteadiness) were only slightly improved by the operation. The result concerning tinnitus seemed to be better after sacrificing the cochlear nerve. The number of patients with ataxia increased postoperatively, although objective ataxia decreased. Dizziness improved regardless of the tumor size.
