The aim of this study is to explore the clinical characteristics,diagnostic methods,surgical procedures and results of typesⅡ to Ⅳexternal auditory canal cholesteatoma.In the 63 cases,there were 39 patients suffering typeⅡexternal auditory canal cholesteatoma,22 patients suffering typeⅢ and 2 patients suffering type Ⅴ.All patients had surgeries to remove the lesion under the microscope,and underwent canaloplasty or tympanoplasty or modified mastoidectomy as well.There were 2 cases occurred meatal stenosis postoperatively ,as well as 2 cases of cholesteatoma recurrenced,and were cured after second operation.Four patients'hearing level were not improve postoperatively due to the severe damage of their ossicular chain.All other patients were cured with one operation,which the cavity with good skin coverage and there has been no recurrence.Temporal bone CT scan has important significance in the diagnosis and classification of external auditory canal cholesteatoma.Prevention and early diagnosis are particularly important.Surgical treatment should completely remove the lesion,restore hearing according to the situation,and appropriate surgical treatment should be taken according to the classification,location of external auditory canal cholesteatoma as well as hearing level of patients.
本研究旨在探讨Ⅱ至Ⅳ型外耳道胆脂瘤的临床特征、诊断方法、手术方式及治疗效果。63例患者中，Ⅱ型外耳道胆脂瘤39例，Ⅲ型22例，Ⅴ型2例。所有患者均在显微镜下行病变切除手术，并行外耳道成形术或鼓室成形术或改良乳突根治术。术后有2例发生外耳道狭窄，2例胆脂瘤复发，二次手术后治愈。4例患者因听骨链严重受损术后听力未改善。其余患者均一次手术治愈，术腔皮肤覆盖良好，无复发。颞骨CT扫描对外耳道胆脂瘤的诊断及分型具有重要意义。预防及早期诊断尤为重要。手术治疗应彻底清除病变，根据情况恢复听力，应根据外耳道胆脂瘤的分型、部位及患者听力情况采取合适的手术方式。
