经乳突进路面神经减压术治疗中耳胆脂瘤并发面神经损害75例

目的 探讨经乳突进路治疗中耳胆脂瘤导致的面神经损伤的最佳方法和疗效。方法 对由中耳胆脂瘤引起周围性面瘫的75例患者，采取经乳突进路面神经减压术。75例中累及垂直段13例，水平段及锥段36例；膝状神经节22例，膝状神经节及迷路段4例。结果 术后随访1～6个月，通过House-Beckmann面神经分级系统评分，结果为Ⅰ～Ⅴ级。结论 对由中耳胆脂瘤累及面神经所致周围性面瘫，及时采取经乳突进路施行面神经减压术治疗，可取得满意效果。

Transmastoid approach treatment for facial paralysis complicated by otitis media cholesteatoma (75 cases report)

Objective To investigate the effect and method of transmastoid approach treatment for facial nerve paralysis complicated by otitis media cholesteatoma. Methods Clinical data of 75 peripheral facial paralysis patients caused by middle ear cholesteatoma were reviewed, including 13 cases involving the vertical segment, 36 cases involving the horizontal segment and cone segment, 22 cases involving the geniculate ganglion, and 4 cases involving the geniculate ganglion and labyrinth segment. Facial decompression surgery was performed through transmastoid apporach. Results In a 1 to 6-month follow-up, facial nerve function rehabilitated to Ⅰ~Ⅴ level based on House- Beckmann facial grading system score. Conclusion Transmastoid approach is a reliable method for facial nerve decompression in the treatment of peripheral facial paralysis caused by middle ear cholesteatoma.
