説明

We report about the otoneurological findings in 31 patients with brain stem lesions and comparison of the results between the standard auditory examinations and the vestibular examinations. The 31 patients were diagnosed as follows; acoustic tumors, 14; meningiomas in cerebellopontine angle, 3; trigeminal neurinoma in CPA; 1; cholesteatoma in CPA, 1; fibroblastoma in CPA, 1; brain stem glioma, 8; brain stem hemorrhage, 3. The abnormal findings of the auditory brain stem responses in these patients were divided into two patterns. In one pattern, the latency of the fifth wave was delayed. In the other, the fifth wave was not apparent. The vestibular findings suggested brain stem disturbance in patients in whom the auditory brain stem responses were also abnormal.
