This report is discussed upon the possibility of the diagnosis of brain stem disturbances by auditory brain stem responses. It is thought that auditory brain stem responses are originated from brain stem, especially pons, by auditory stimuli.In patients with acoustic tumor, those findings of auditory brain stem responses were no response that was not recorded from the first wave to the fifth wave.On the other hand, in patients with other cerebellopontine angle tumor except acoustic tumor, that is meningioma, cholesteatoma and fibroblastoma, the fifth wave was abnormally recorded in all six cases.In patients with the IVth ventricle tumor, that is under the condition that brain stem is pressed extramedullary, auditory brain stem responses were normally recorded. And in patients with parenchymal pontine lesions, that is pontine glioma and hemorrhage in pons, auditory brain stem responses were abnormally recorded in the fifth wave. Almost of them, the findings was that the fifth wave was unable to be recognized.
