[Outcome of cochlear implantation in prelingual pediatric auditory neuropathy].
OBJECTIVE
To explore the electrophysiological results and rehabilitation outcome of two prelingually deafened pediatric cochlear implant patients with auditory neuropathy.


METHODS
Preoperative audiological evaluation, intra-postoperative electrically evoked auditory brainstem response (EABR) and neural response telemetry (NRT) record for the two cases were conducted in Beijing Tongren Hospital. A one year follow-up was performed. Data collected before and at 6,12-month intervals after implantation were compared with that from control pediatric cochlear implant patients matched for the same duration of implant use as this two cases.


RESULTS
The two children implanted had not had any postoperative medical or cochlear implant device complications. Intraoperative EABR and NRT were elicited in case 1 with unrepeatable waveforms. After 12 months of training, Case 1 had shown significant improvements in sound detection, speech perception abilities and communication skills, which was better than the control group, and the electrophysiological results became normal. Case 2 had also benefited from cochlear implantation, even though no recognizable NRT was found until he returned 12 month after the operation. CONTUSIONS: The desynchronization of auditory path had been changed after the electrical stimulation ongoing 12 months for children with auditory neuropathy. The two children had not had any complications postoperatively, and each child had shown improved listening and communication skills. Cochlear implantation could help patients with auditory neuropathy to improve their communication skill and go back to the main stream.
