面神经异常是耳蜗前庭畸形患者的潜在问题。本文报告一例颞骨内面神经分叉处的人工耳蜗植入手术。在第一次手术中，面神经分叉遮挡了岬和圆窗。由于缺乏耳蜗底回的标志，很难进行耳蜗造口术，第一次耳蜗造口术的手术尝试被放弃。在第一次手术后使用重建的颞骨和耳蜗3D图像进行重复CT扫描，然后在翻修手术中成功打开耳蜗。重建的三维CT图像是非常有用的，以确定在这种情况下，这种困难的颞骨解剖耳蜗造口术的网站。
Facial nerve anomalies are a potential problem in patients with cochleovestibular malformations. A case of cochlear implant (CI) surgery in the presence of intra-temporalbone facial nerve bifurcation is presented. During the first surgery, the facial nerve bifurcation obscured the promontory and round window. It was difficult to perform cochleostomy because of the lack of landmarks of the basal turn of the cochlea, and the first surgical attempt at cochleostomy was abandoned. A repeat CT scan was performed after the first surgery with reconstructed 3D images of the temporal bone and the cochlea, and then the cochlea was successfully opened at revision surgery. Reconstructed 3D CT images were very useful to identify the site of cochleostomy in this case with such difficult temporal bone anatomy.
