Auditory brainstem response and eighth nerve lesions: a review and presentation of cases

A review of salient features in the use of auditory brainstem response for the detection of eighth nerve lesions is presented. Three cases of acoustic tumors are discussed. These cases represent a normal pure-tone audiogram, one with a moderate loss, and one with no measurable hearing on the affected side. Interpretation of the auditory brainstem response in these cases is discussed in light of the various auditory brainstem response measures presented and the pure-tone audiometric data.
