Abstract

(1) Background: Cochlear implants (CIs) are widely applied to recover audition for patients with severe degrees of or total hearing loss. Electrical stimulation using the electrically evoked ABR (E-ABR) can be recorded in CI recipients through the device. This work was designed to study E-ABR recorded individually from different channels located at the apical, middle, and basal cochlear regions in comparison to their simultaneous separated or adjacent combined recordings. (2) Methods: This study included 17 children fitted with unilateral cochlear implants. All children were subjected to impedance measurement, electrical compound action potentials (ECAP), and E-ABR recording of three channels located at the apical, middle, and basal cochlear regions. This was followed by simultaneous E-ABR recording of the three "separated" channels in comparison to E-ABR recording from three adjacent channels located at the middle cochlear region. (3) Results: Similar E-ABR latencies and amplitudes were found using either individual or simultaneously separated or adjacent combined recording. However, the mean amplitude measures of E-ABR for combined adjacent channels showed a positive correlation with the applied current level. (4) Conclusions: Combined E-ABR recording from adjacent channels is a faster and more reliable technique that can be used effectively without compromising the results of the recorded E-ABR.

人工耳蜗中的听觉脑干电反应测听：新的记录范例。

(1) 背景：人工耳蜗（CI）被广泛应用于重度或全聋患者的听力恢复。通过该设备可记录电诱发 ABR（E-ABR）对 CI 受体的电刺激。这项工作旨在研究从位于耳蜗顶端、中部和基底的不同通道单独记录的 E-ABR 与同时分离或相邻合并记录的 E-ABR 的比较。(2) 方法：这项研究包括 17 名安装了单侧人工耳蜗的儿童。所有儿童都接受了阻抗测量、电复合动作电位（ECAP）和位于耳尖、中间和基底耳蜗区的三个通道的 E-ABR 记录。然后同时对三个 "分离 "通道进行 E-ABR 记录，并与位于耳蜗中部的三个相邻通道的 E-ABR 记录进行比较。(3) 结果：无论是单独还是同时分离或相邻组合记录，都发现了相似的 E-ABR 延迟和振幅。然而，合并相邻通道的 E-ABR 平均振幅测量值与应用的电流水平呈正相关。(4) 结论：从相邻通道合并记录 E-ABR 是一种更快、更可靠的技术，可在不影响 E-ABR 记录结果的情况下有效使用。
