Speech, impedance, and auditory brainstem response audiometry in brainstem tumors. Importance of a multiple-test strategy.
Speech, impedance, and auditory brainstem response audiometric data were determined for four patients with intracranial tumor. Although the results of any individual measure may be ambiguous, consideration of the overall pattern of results on all three measures, in combination with audiometric sensitivity level, can lead to relatively precise site localization of brainstem auditory disorders.
