目的确定电极电压（EV）测量是否可能适合作为检测人工耳蜗（CI）中耳蜗外电极的测试。方法对17例人工耳蜗植入者进行耳蜗电生理检查。研究了重复性、刺激水平、CI有源电极位置、（有源）记录电极位置和刺激模式（对于Nucleus器械）的影响。结果/讨论当有源记录电极放置在同侧耳垂上时，在单极模式下进行的记录显示出良好的可重复性;电压与预期的刺激水平呈线性增加。在部分插入/迁移器械、所有电极激活的完全插入器械和停用基底电极的器械之间，基底电极的EV差异很大[对于最基底电极，χ 2（2）= 10.2，p < 0.05]。与单极回流电极相比，Nucleus器械的EV对于阵列上的电极较小，但使用耳蜗外电极的参与者除外。我们认为，在这种情况下，电极阵列周围的纤维化促进了电流流过圆窗。结论该测试似乎是一种可行的方法，以检测电极迁移和耳蜗外电极在成年CI用户，也可能是敏感的不适引起的电流泄漏从耳蜗的基底端。
Objectives To determine if Electrode Voltage (EV) measurements are potentially suitable as a test for detecting extra-cochlear electrodes in cochlear implants (CIs). Methods EV measurements were made using surface electrodes in live mode in 17 adult cochlear implant (CI) users. Repeatability, the effects of stimulation level, CI active electrode position, (active) recording electrode position and stimulation mode (for Nucleus devices) were investigated. Results/discussion Recordings made in monopolar mode showed good repeatability when the active recording electrode was placed on the ipsilateral earlobe; voltages increased linearly with stimulation level as expected. EVs for basal electrodes differed greatly between partially inserted/migrated devices, fully inserted devices with all electrodes activated, and those with deactivated basal electrodes [χ 2(2) = 10.2, p < 0.05 for the most basal electrode]. EVs for Nucleus devices were small for electrodes on the array when compared to those for monopolar return electrodes, except for the participant with extra-cochlear electrodes. We argue that fibrosis around the electrode array facilitated current flow across the round window in this case. Conclusion The test appears to be a viable approach to detect electrode migration and extra-cochlear electrodes in adult CI users and may also be sensitive to discomfort caused by current leakage from the basal end of the cochlea.
