外耳道胆脂瘤的临床特征和治疗(附25例报告)

Clinical features and management of cholesteatoma of external auditory canal(Report of 25 cases)

目的探讨外耳道胆脂瘤的临床特征和治疗方法。方法回顾性分析我科1995～2007年收治的25例外耳道胆脂瘤患者的临床资料。结果对25例外耳道胆脂瘤患者根据不同病变范围采用不同的手术治疗,对8例外耳道病变范围小、骨质破坏较轻者采用外耳道清理术;17例因病变范围广、骨质破坏较重、胆脂瘤侵入中耳腔者采用乳突改良根治术或乳突根治术治疗。结论外耳道胆脂瘤可以造成广泛破坏,术前颞骨薄层CT扫描对诊断有较大帮助,应根据不同病变范围而采用不同的治疗方式。

Objective To investigate the clinical features and treatment of cholesteatoma of external auditory canal（CEAC）.Methods Clinical data of 25 patients suffering from CEAC treated in our department from 1995 to 2007 was analysed retrospectively.Results Conservative management or surgical procedure was chosen according to the range of lesion.Of all the 25 cases,cholesteatoma clearing was applied to 8 patients with minor bony invasion and modified mastoidectomy or radical mastoidectomy was chosen to the other 17 cases with severe bony invasion under general or local anaesthesia.Conclusion CEAC can cause extensive erosion.Preoperative high-resolution CT scan of temporal bone can be used for identifying the range of the primary lesion and determining the proper management strategy for CEAC.Conservative management or surgical procedures should be chosen according to the range of lesion.s
