经乳突面神经减压治疗累及膝状神经节外伤性面瘫的疗效分析

Transmastoid facial nerve decompression for treating traumatic facial paralysis involving the geniculate ganglia

目的探讨经乳突面神经减压治疗累及膝状神经节的外伤性面瘫的疗效。方法回顾性分析30例外伤性面瘫行经乳突面神经减压术的病例资料,比较手术前后面神经功能、纯音听阈的变化。结果30例患者术后面神经功能均得到不同程度改善,其中26例(87%)恢复至HB I级或II级。13例听骨链完整而术中行听骨链重建者,术后听力10例(77%)损失在10 dB以内,3例(23%)损失在10~20 dB。结论经乳突面神经减压术治疗累及膝状神经节的外伤性面瘫安全有效,术后听力损失较小。

Objective To explore the clinical effects of geniculate ganglion decompression of the facial nerve using the transmastoid-epitympanum approach in patients with traumatic facial nerve paralysis.Methods A retrospective analysis of 30 traumatic facial nerve paralysis cases was conducted.Facial nerve function and hearing levels were compared.Results All patients had improved facial function after surgery,of which 26 cases recovered to HB I or II level.The adverse effects on their auditory function were less than 10 dB in most cases.Conclusion The transmastoid-epitympanum approach to the decompression of the geniculate ganglion is simple,minimally invasive,safe,and effective,which results in little postoperative hearing change.
