OBJECTIVES
To describe the influence of stimulus parameters on aberrant facial nerve stimulation in cochlear implant users.
METHODS
Retrospective case series (three ears - two patients). Cochlear implant patients with severe facial nerve stimulation and degraded speech comprehension who underwent re-implantation with Neuro Zti EVO (Oticon Medical).
RESULTS
In all three ears, side effects evoked by aberrant facial nerve stimulation could be resolved and thereby speech comprehension was improved.
CONCLUSIONS
Aberrant facial nerve stimulation in cochlear implant patients was successfully resolved by re-implantation. We hypothesize that one or more of the specific stimulus paramet ers are responsible for this success: combined common ground and monopolar stimulation mode, asymmetric pulse waveform with active anodic leading first phase followed by slow capacitive discharge, and pulse width modulation for loudness coding.
目的
描述刺激参数对人工耳蜗使用者异常面神经刺激的影响。
方法
回顾性病例系列研究（3耳 - 2例患者）。对接受Neuro Zti EVO（奥迪康医疗公司）再次植入的、存在严重面神经刺激且言语理解能力下降的人工耳蜗患者进行研究。
结果
在所有3耳中，异常面神经刺激引起的副作用均得到解决，从而言语理解能力得到改善。
结论
通过再次植入成功解决了人工耳蜗患者的异常面神经刺激问题。我们推测，一个或多个特定刺激参数促成了这一成功：共同接地和单极刺激模式相结合、具有主动阳极领先第一阶段随后缓慢电容放电的不对称脉冲波形以及用于响度编码的脉宽调制。
