摘要

面神经刺激(FNS)是人工耳蜗植入术中的一种并发症,当电流从耳蜗逃逸到附近的面神经时。可以使用不同的管理方法来减少其影响,尽管更改可能会导致CI用户不太理想的拟合,最终降低语音感知。目的探讨FNS的病因,探讨FNS的治疗策略,评价FNS患者的语音识别能力。方法经本院伦理委员会批准的回顾性研究。从CI组的档案中,选择在手术中或术后任何时间被确定为FNS的患者。数据收集包括:CI制造商、电极阵列类型、植入年龄、听力损失病因、FNS识别日期、产生FNS的电极数量、FNS管理措施、安静和噪音下的语音识别。结果儿童7例,成人25例。导致FNS的病因有耳蜗畸形、头部外伤、脑膜炎和耳硬化;主要的作用包括刺激水平的降低,随后是电极的失活。完成FNS测试的患者在安静状态下的平均语音识别率分别为86%和80%。然而,有很大的可变性,从0%的安静到90%的噪音语音识别。结论引起FNS的病因与耳蜗形态改变有关。面部神经的刺激可以用语音处理器编程参数来解决;然而,预测结果是不可能的,因为结果取决于其他变量。

Hearing Performance in Cochlear Implant Users Who Have Facial Nerve Stimulation
Abstract Introduction Facial nerve stimulation (FNS) is a complication in cochlear implant (CI) when the electrical current escapes from the cochlea to the nearby facial nerve. Different management to reduce its effects are available, although changes might result in a less-than-ideal fitting for the CI user, eventually reducing speech perception. Objective To verify the etiologies that cause FNS, to identify strategies in managing FNS, and to evaluate speech recognition in patients who present FNS. Methods Retrospective study approved by the Ethical Board of the Institution. From the files of a CI group, patients who were identified with FNS either during surgery or at any time postoperatively were selected. Data collection included: CI manufacturer, electrode array type, age at implantation, etiology of hearing loss, FNS identification date, number of electrodes that generated FNS, FNS management actions, and speech recognition in quiet and in noise. Results Data were collected from 7 children and 25 adults. Etiologies that cause FNS were cochlear malformation, head trauma, meningitis, and otosclerosis; the main actions included decrease in the stimulation levels followed by the deactivation of electrodes. Average speech recognition in quiet before FNS was 86% and 80% after in patients who were able to accomplish the test. However, there was great variability, ranging from 0% in quiet to 90% of speech recognition in noise. Conclusion Etiologies that cause FNS are related to cochlear morphology alterations. Facial nerve stimulation can be solved using speech processor programming parameters; however, it is not possible to predict outcomes, since results depend on other variables.
