经乳突面神经减压术治疗颞骨外伤性面瘫

Facial Nerve Decompression via Mastoid Approach for Traumatic Facial Paralysis

目的:对经乳突面神经减压术治疗颞骨外伤性面瘫的临床效果、手术时机及减压范围进行探讨,为临床提供治疗经验。方法:回顾性分析29例颞骨外伤性面瘫患者的临床资料,以House-Brackmann(H-B)评价系统评估手术效果,采用χ~2检验进行统计分析。结果:29例患者均手术成功,术后6个月复查,所有患者的面神经功能均有不同程度恢复,外伤后2个月内者与2个月以上者的面神经功能,恢复至Ⅰ、Ⅱ级的差异有统计学意义(P<0.05)。结论:面神经减压术是治疗外伤性面瘫的有效手段,外伤后2个月内手术效果较好。

Objective:To Study the final facial function outcomes,optimal timing and the range of resecton of facial nerve decompression via mastoid approach for traumatic facial paralysis,and to provide experience for clinical treatment.Methods:Clinical data of 29 patients with temporal bone traumatic facial paralysis were retrospectively analyzed.House-Brackmann(H-B) system was used to evaluate the recovery of facial nerve function, chi-square test was employed for statistic analysis.Results:29 patients were operated successfully.Facial nerve function of all patients was recovery partly at 6 months of review after the operation.Recovery of facial nerve function to level Ⅰ,Ⅱ between patients within 2 months and beyond 2 months had statistical significant differences(P<0.05).Conclusion:Facial nerve decompression is an effective method to treat traumatic facial paralysis,and the effect of the operation was better within 2 months after the trauma.
