目的探讨鼓室成形术后迟发性面瘫发生的相关因素。方法回顾性分析2008年1月至2012年6月所有入住我院行鼓室成形术的患者,根据是否发生迟发性面瘫,分为面瘫组及非面瘫组,使用Logistic回归分析发生迟发性面瘫的相关因素。结果共纳入458例鼓室成形术患者,其中面瘫组11例。两组在性别、年龄之间均无明显差异。Logistic回归分析提示鼓索神经牵拉、面神经水肿、面神经骨管缺失、鼓室填塞物成分、病毒感染与面瘫发生密切相关,而术后出血、鼓索神经中断显示有较强的差异趋势。结论鼓室成形术后迟发性面瘫可能是由于面神经骨管缺失、面神经水肿、鼓索神经牵拉、病毒感染等多种因素综合作用而致。
Objective To investigate the related factors of delayed facial paralysis after tympanoplasty. Methods All patients undergoing tympanoplasty admitted to our hospital from January 2008 to June 2012 were retrospectively analyzed. According to whether there was delayed facial paralysis, the patients were divided into facial paraplegia group and non-facial paralyzed group, Logistic regression analysis was used to analyze the delayed facial paralysis Related factors. Results A total of 458 tympanoplasty patients were enrolled, including 11 cases of facial paralysis. There was no significant difference between the two groups in gender and age. Logistic regression analysis showed that the traumatic nerve pull, facial edema, facial nerve tube loss, tympanic stuff composition, viral infection and facial paralysis were closely related to the occurrence of postoperative bleeding, and disruption of the chorda showed a strong trend. Conclusions Delayed facial paralysis after tympanoplasty may be caused by the combined action of multiple factors including loss of facial nerve tube, facial nerve edema, chordoma pull, and viral infection.
