OBJECTIVE To evaluate the benefit of bilateral cochlear implants (BCIs) in prelingually deafened children on hearing rehabilitation as well as on speech and language development. METHOD Two cases of congenital profound deaf children, who received unilateral cochlear implantation (CI, MEDEL C40+) on the age of 2 and 7.5, respectively, were performed(More)
OBJECTIVE To study the auditory electrophysiological characteristics of the auditory neuropathy. METHODS Ten patients were diagnosed as auditory neuropathy. The history, pure tone audiometry, stapedial reflex, auditory brainstem response, electrocochleogram, distortion product otoacoustic emission and his contralateral suppression of white noise, middle(More)
In order to delete the contamination of acoustic stimulus artefact in average evoked cochlear microphonics by surface recording, an application of adaptive filtering technique for cancelling the stimulus artefact from the cochlear microphonics was proposed. The results demonstrated that in normal hearing ears, the cochlear microphonic potentials (CM) which(More)
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(More)
OBJECTIVE To evaluate the feasibility and value of integrated methods to assess auditory pathway integrity. METHOD Twenty-four cases of bilateral profoundly-deafened individuals who were considered as the candidates of cochlear implantation were included in this study. Auditory pathway integrity from these candidates of cochlear implantation were assessed(More)
