目的：探讨外耳道胆脂瘤合并中耳乳突炎及鼓膜穿孔的治疗方法。方法采用回顾性研究方法，分析40例外耳道胆脂瘤及其并发症的临床诊疗情况。术后随访半年-1年。统计学分析采用Fisher精确概率检验法分别检验中耳乳突炎和鼓膜穿孔手术处理方式的差异性有无统计学意义。结果①40病例均无胆脂瘤复发；②改良乳突根治术对合并中耳乳突炎的愈合情况无统计学差异（p>0.05，p=0.375)；③鼓室成形术对合并鼓膜穿孔患者的鼓膜愈合情况无明显差异（p>0.05，p=0.426）。结论外耳道胆脂瘤合并中耳乳突炎及鼓膜穿孔者可先行胆脂瘤取出术，术后随访观察，如无治愈二期行改良乳突根治术和鼓室成形术。

objective To report treatment outcomes of external auditory canal cholesteatoma combined with mastoiditis and tympanic membrane perforation. Methods This is a retrospective study of 40 cases with external auditory canal choleste?atoma. All cases were followed six months to 1 year. Treatment outcomes by different surgical approaches were compared us?ing Fisher's exact probability test. Results (1) There was no recurrence among the cases during the following up to 1 year;(2) There was no statistically significant difference regarding eradication of middle ear infection among different surgical ap?proaches (p=0.375);(3) There was no statistically significant difference among different surgical approaches regarding tym?panic membrane healing (p=0.426). Conclusion The key in treatment of external auditory canal cholesteatoma with mastoid?itis and tympanic membrane perforation is the removal of cholesteatoma. Tympanoplasty and ear drum repair should be based on findings during mastoidotympanectomy and may need to be completed in phaseⅡ.
