Abstract:
OBJECTIVE:To investigate the character of 80 Hz auditory steady-state evoked potentials in auditory neuropathy (AN) patients and the correlation between it and ABR.
METHOD:The 80 Hz auditory steady-state evoked potentials and ABR to 95 dBnHL (1000 Hz) tone-pip stimuli were recorded from the scalp in patients with AN and normal subjects. The difference of the waveforms between AN ears and normal ears was compared.
RESULT:In 85.4% AN ears the 80 Hz auditory steady-state evoked potentials and ABR were simultaneously present. Their amplitudes were low or extremely low. The I and III waves of ABR were absent. The 80 Hz auditory steady-state evoked potentials and ABR were simultaneously absent, in 14.6% AN ears, but were present in all normal ears.
CONCLUSION:The 80 Hz auditory steady-state evoked potentials and the V wave of ABR may come from the same brainstem sources.
