摘要
目的 :探讨化脓性中耳炎并发面瘫的临床特征及治疗方法。方法 :回顾分析 12例化脓性中耳炎并发面瘫的临床资料 ,1例由急性中耳炎引起 ,11例由慢性中耳炎引起。出现面瘫的时间为 1～ 330d ,平均5 8d。结果 :化脓性中耳炎并发面瘫发生率为 2 .6 5 %。 12例中 ,10例中耳、乳突腔内有胆脂瘤或同时有肉芽组织 ,2例仅有肉芽组织。 2例面神经骨管完整 ,10例面神经部分骨管破坏 (2例面神经部分缺失 ) ,其中单纯累及鼓室段 6例 (6 0 % ) ,单纯累及垂直段和迷路段各 1例 (10 %、10 % ) ,同时累及乳突段和鼓室段 2例(2 0 % )。术后 6例 (5 0 % )患者面神经功能完全恢复 ,3例 (2 5 % )部分恢复 ;3例 (2 5 % )术后无恢复。结论 :耳源性面瘫的发病率明显降低。面神经骨管破坏、缺损以及有胆脂瘤是耳源性面瘫的主要致病因素。面神经鼓室段是受累的好发部位。手术治疗是降低疾病危害。
Objective: To explore the clinical feature and treatment of facial nerve paralysis due to suppurative otitis media. Method:The clinical data of 12 patients with otogenic facial paralysis was analyzed retrospectively. 1 of 12 patients resulted from acute suppurative otitis media, while other 11 patients from chronic otitis media. The duration of facial palsy was 1～330 days, average 58 days. Results: The incidence rate of facial paralysis due to suppurative otitis media was 2.65%. 10 out of 12 patients performed surgery had cholesteatoma or with granulation in their middle ear cavities and facial nerve partial absence or bone of fallopian canal destruction or dehiscence. Other 2 patients had only granulation in their surgical fields and had no fallopian canal destruction.The tympanic segment was the most common site of involvement in 8 patients. 6 patients demonstrated complete facial function recovery after surgery, 3 patients patial recovery, and other 3 patients no recovery. Conclusion: The incidence rate of facial paralysis due to suppurative otitis media has been low down in these years. The dehiscent facial canal and middle ear cholesteatoma are the major risk factors of facial paralysis resulting from suppurative otitis media and the tympanic segment is the most common site of involvement. The surgery is effective to reduce the damage of the disease and recover the facial nerve functions.
