Thirty-eight adult cochlear implants have been performed at the University of Minnesota. Facial nerve stimulation by the implant in response to sound has been noted in four of these cases. Three of the four were patients whose sensorineural hearing loss was caused by cochlear otosclerosis. In each case it was possible to place the electrodes, however multiple leads had to be deprogrammed in order to avoid facial nerve stimulation. In each case characteristic radiographic findings of cochlear otosclerosis could be identified on preoperative temporal bone computed tomography scans. Although facial nerve stimulation has been described as a complication of cochlear implantation, it has not been reported to be associated with cochlear otosclerosis. Postoperative programming of the implant may be limited by facial nerve stimulation. In some cases these limits may reduce the efficacy of the device. This possibility should be taken into account during preoperative counseling of patients with cochlear otosclerosis considering cochlear implantation.
明尼苏达大学已为38名成人实施了人工耳蜗植入手术。在其中4例病例中，观察到植入物对声音产生反应时刺激了面神经。这4例中的3例患者感音神经性听力损失是由耳蜗性耳硬化症引起的。在每例病例中，电极都能够放置，但为了避免刺激面神经，不得不对多条导线进行去程控。在每例病例中，术前颞骨计算机断层扫描上都能识别出耳蜗性耳硬化症的特征性影像学表现。虽然面神经刺激已被描述为人工耳蜗植入的一种并发症，但尚未报道其与耳蜗性耳硬化症有关。植入物的术后程控可能会受到面神经刺激的限制。在某些情况下，这些限制可能会降低设备的功效。在考虑为耳蜗性耳硬化症患者进行人工耳蜗植入的术前咨询过程中，应考虑到这种可能性。
