Cochlear implantation becomes more common with every passing year. Since adequate exposure of the round window requires a facial recess approach, facial nerve variation and anomalies could potentially alter the surgical approach significantly. We report the case of a patient with a variation of facial nerve anatomy. The nerve was found to be lateral to the annulus in its mastoid segment and required retrofacial dissection to approach the round window. A good result was achieved in this patient, demonstrating that facial nerve anomalies need not be a barrier to successful implantation. The reported congenital anomalies of the facial nerve are discussed, along with their influence on cochlear implantation. A knowledge of these variations is mandatory for those engaged in implant surgery.
随着时间的推移，人工耳蜗植入术越来越普遍。由于充分暴露圆窗需要采用面神经隐窝入路，面神经的变异和异常可能会显著改变手术入路。我们报告了一例面神经解剖变异的患者。发现该神经在其乳突段位于鼓环外侧，需要通过面神经后入路来接近圆窗。该患者取得了良好的效果，表明面神经异常不一定是成功植入的障碍。本文讨论了已报道的面神经先天性异常及其对人工耳蜗植入的影响。对于从事植入手术的人员来说，了解这些变异情况是必不可少的。
