[Electronystagmographic and videonystagmographic studies in cerebello-pontine angle tumors]

Otoneurological investigations were carried out in 24 patients with cerebello-pontine angle tumors demonstrated in computed tomography. Standardized history taking was followed by electronystagmographic and videonystagmographical tests. In no case correct electrophysiological results were obtained. Eye-tracking test and gaze nystagmus were most frequently abnormal and together with other data these abnormalities indicated the location of the process. A more extensive use of videonystagmography was postulated.
