22核多通道人工耳蜗受者开始经历与人工耳蜗相关的严重前庭刺激，该患者的经历引发了一项旨在确定与人工耳蜗相关的前庭刺激频率的研究，研究对象包括17名随机选择的使用人工耳蜗的患者，包括14名22核和3名Med-El Combi 40装置。植入物通过单独通道和使用用户正常设备设置的声场80 db宽带噪声进行刺激，眼球运动用红外视频震动仪监测。只有一名使用Med-El Combi 40的受试者对耳蜗刺激表现出一致且强烈的眼部反应，但没有主观症状。作者得出结论，多通道人工耳蜗植入可能会激活前庭眼，但不常见，可能没有临床意义。
The recipient of a Nucleus 22 multichannel cochlear implant began to experience severe vestibular stimulation related to the implant, This patient's experience initiated a study with the objective of determining the frequency of implant-related vestibuloocular stimulation, Subjects consisted of 17 randomly selected patients who use cochlear implants, Included in the study were 14 Nucleus 22 and three Med-El Combi 40-devices. Stimulation of the implants was performed both by individual channel and with sound field broad-band 80-dB noise using the users' normal device settings, Eye movements were monitored with infrared videonystagmography. Only one subject, who used a Med-El Combi 40, showed a consistent and strong ocular response to cochlear stimulation but had no subjective symptoms, The authors conclude that vestibulo ocular activation is possible with multichannel cochlear implants but is infrequent and may not be clinically significant.
