The cochlear implant device has the capacity to measure the electrically evoked compound action potential of the auditory nerve. The neural response telemetry is used in order to measure the electrically evoked compound action potential of the auditory nerve.
To analyze the electrically evoked compound action potential, through the neural response telemetry, in children with bilateral cochlear implants.
This is an analytical, prospective, longitudinal, historical cohort study. Six children, aged 1-4 years, with bilateral cochlear implant were assessed at five different intervals during their first year of cochlear implant use.
There were significant differences in follow-up time (p=0.0082) and electrode position (p=0.0019) in the T-NRT measure. There was a significant difference in the interaction between time of follow-up and electrode position (p=0.0143) when measuring the N1-P1 wave amplitude between the three electrodes at each time of follow-up.
The electrically evoked compound action potential measurement using neural response telemetry in children with bilateral cochlear implants during the first year of follow-up was effective in demonstrating the synchronized bilateral development of the peripheral auditory pathways in the studied population.
人工耳蜗装置能够测量听神经的电诱发复合动作电位。神经反应遥测技术用于测量听神经的电诱发复合动作电位。
通过神经反应遥测技术分析双侧人工耳蜗植入儿童的电诱发复合动作电位。
这是一项分析性、前瞻性、纵向、历史性队列研究。对6名年龄在1至4岁的双侧人工耳蜗植入儿童在人工耳蜗使用的第一年中的五个不同时间点进行评估。
在T-NRT测量中，随访时间（p = 0.0082）和电极位置（p = 0.0019）存在显著差异。在每次随访时测量三个电极之间的N1-P1波幅时，随访时间和电极位置之间的相互作用存在显著差异（p = 0.0143）。
在随访的第一年中，使用神经反应遥测技术测量双侧人工耳蜗植入儿童的电诱发复合动作电位，有效地证明了所研究人群中周围听觉通路的双侧同步发育。
