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.
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.
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.
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.
探讨内耳畸形和内耳正常儿童人工耳蜗植入后电极阻抗及神经反应遥测（NRT）值的变化及差异。
88例多通道人工耳蜗植入儿童参与本研究。将儿童分为内耳畸形组和内耳正常组。测试电极阻抗值和NRT值。
两组电极阻抗变化呈现相似的变化模式。两组电极阻抗值无差异（P>0.05）。两组电极神经反应遥测值变化呈现相似的变化模式。两组电极阻抗值有显著差异（P<0.05）。从电极22到电极1，NRT值逐渐升高。
人工耳蜗植入使用的前3个月内，不同编程时段和电极的数值存在差异。为获得更好的听力，需要频繁进行编程。
