摘　　要：目的分析中耳乳突术后迟发性面瘫的产生原因和预防方法。方法回顾性分析1995～2007年我院6例中耳乳突术后迟发性面瘫患者的临床资料，予保守治疗，面神经功能评估采用House—Brackmann分析法。结果6例患者在术后2～8d出现面瘫，面瘫程度为Ⅲ～Ⅳ级，采用保守治疗后，均完全恢复。结论中耳乳突术后发生的迟发性面瘫为不完全面瘫，非神经直接损伤，属神经失用，经保守治疗后，均可完全恢复。其病因与面神经骨管缺损或骨管损伤、鼓索神经损伤、填塞物刺激、血肿压迫、手术熟练程度等有关。Aim To explore the causes and preventions of delayed facial nerve paralysis induced by mastoidectomy of otitis media. Meth- ods 6 cases of mastoidectomy performed in our hospital with conservative treatment from 1995 to 2007 were reviewed and analyzed. Resuits Delayed facial nerve paralysis occurred in the 6 cases 5 - 8 days after the mastoidectomy, the degree of paralysis ranging grade III to grade IV according to House - Brackmamn Grading. With conservative treatment, all patients recovered from facial nerve paralysis. Conclusion The delayed facial nerve paralysis induced by mastoideetomy of otitis media is not completely paralyzed and not caused by direct damage to nerves, but caused by temporary disfunction of nerve. Conservative treatment is effective in bringing about full recovery. The cause of the paralysis is related to the malformation of bone - tube of facial nerve or injuries to bone - tube, injuries to ehorda tympani nerve,reaction to stemming materials,pressure caused by haematoma, and nerve paralysis proficiency of the surgeon.
