Abstract:
OBJECTIVE:To investigate the changes and determine the difference of electrode impedance and neural response telemetry ( NRT) value with cochlear implants in children with malformed inner ear and normal inner ear.
METHOD:Eighty-eight children with multi-channel cochlear implants participated in this study. Children were divided into malformed inner ear group and normal inner ear group. To test the electrode impedance values and NRT value.
RESULT:The changes of electrode impedance showed the similar changing pattern in two groups. There was not different in electrode impedance values between the two groups (P > 0.05). The changes of electrode neural response telemetry values showed the similar changing pattern in two groups. There was significantly different in electrode impedance values between the two groups (P < 0.05). The NRT were going up higher from electrode 22 to electrode 1.
CONCLUSION:The values vary are different programming sessions and electrodes during the first 3 months of cochlear implant use. To acquire better hearing frequent programming sessions are necessary.
