• Clinical Evaluation of Vestibular Schwannomas and other Cerebellopontine Angle Tumors.

抄録

Clinical studies of forty cerebellopontine angle tumors including thirty-one vestibular schwannomas were performed. The results of audiological and radiological testing were analyzed and screening methods for Cerebellopontine angle tumors were evaluated. Although auditory brainstem response (ABR) tests reveal the highest positive rate of detection in vestibular schwannoma patients, ABR tests are difficult to perform routinely in hospitals, especially in private clinics. The combination of conventional radiographs (Stenvers views) and caloric tests had a higher positive rate of detection than ABR tests, whereas these testing methods alone both had lower positive rates. Our data shows the high efficiency of routine radiographs and caloric tests for detection of patients with suspected acoustic neurinomas. Further evaluation including ABR tests and magnetic resonance imaging (MRI) should be performed after initial testing. In our study, all of the other cerebellopontine angle tumors showed abnormalities in ABR tests. ABR tests are also efficient in the investigation of patients with other cerebellopontine angle tumors.
