【论文摘要】 目的 探讨外耳道胆脂瘤的手术治疗方法。方法 回顾性分析经临床和病理确诊的35例外耳道胆脂瘤的临床诊治情况。局限于外耳道的外耳道胆脂瘤20例(I型),行外耳道胆脂瘤清除术;侵及中耳的外耳道胆脂瘤15例(II型),行乳突根治术及鼓室成形术。所有病例随访3个月~3年。结果 单纯外耳道胆脂瘤患者,术后无复发;侵及中耳及乳突的外耳道胆脂瘤,手术成功率为86.7%(13/15)。结论 外耳道胆脂瘤根据侵及范围,采用不同手术方法治疗,疗效满意。?

【Abstract】 Objective To explore the therapy of external auditory cholesteatoma. MethodsA retrospective study was carried out among 35 cases with this lesion treated in our hospita1.All the cases were diagnosed on the basis of pathological determination. Among the cases,20cases limited in external auditory canal were treated with focus clearance; 15 cases invading to middle ear, were treated with mastoidotympanectomy and tympanoplasty;。with period of 3 months to 3 year follow-up. Results The successful rate was 100%(20/20)in group I,86.7% (13/15)in group II, Conclusion Basis of its range, external auditory canal cholesteatoma was treated with focus clearance, mastoidotympanectomy and canaloplasty of external auditory meatus. ?

外耳道胆脂瘤是一种由于各种原因引发外耳道发生脱屑、胆固醇结晶堆积、角化上皮包裹所致的一种慢性炎性疾病,如不及时治疗,病变可压迫周围骨质,导致骨质吸收、破坏,并可产生严重并发症[1]。回顾2001年11月至2006年11月7年间收治的35例外耳道胆脂瘤患者,对其临床资料进行分析、总结如下。?
1 资料与方法?
1.1 临床资料 外耳道胆脂瘤共35例(35耳),男27耳,女8耳,年龄7~65岁。病史1~20年。其中因耳痛、外耳流脓、听力差就诊的33耳,耳后乳突区形成瘘管后流脓而就诊2耳,伴有周围性面瘫而就诊2例,因严重眩晕就诊1例,所有患者中,有耳部手术史的8例。耳部检查:根据外耳道胆脂瘤侵及范围,将病变分为二型,I型单纯性外耳道胆脂瘤20耳;II型是外耳道胆脂瘤侵及中耳乳突 15耳。所有患者术前均作纯音测听,26耳为传导性聋,语言频率500~2 000 Hz的气导平均阈值在40~70 dBHL之间,6耳为混合性聋,3耳为感音神经性聋。影像学检查:术前颞骨CT扫描,包括水平和冠状位,I型表现为外耳道扩大,部分伴外耳道后壁骨质破坏,II型表现为外耳道扩大、外耳道后壁骨质破坏、鼓室及鼓窦、乳突显示骨质破坏者有密度减低区,边缘清晰,其中1耳外半规管有明显骨质破坏,2耳伴面神经水平段骨管骨质局限性缺损。
