外耳道胆脂瘤的临床诊疗进展

目的外耳道胆脂瘤（EACC）是耳鼻咽喉科的一种少见疾病，早期病变特征不典型，常被漏诊、误诊，虽为良性肿瘤，但其生物学上具有侵蚀性，早期诊断、早期治疗非常重要。由于其发病率比较低，关于分型、分期国际上尚无统一标准，治疗方式主要包括保守治疗和手术清理胆脂瘤病变，因此需要进一步收集更多的数据进行全面的研究。本文系统地回顾国内外相关文献，并总结分析EACC的病因、发病机制及临床特点，详细描述EACC的诊断与治疗情况，以期引起耳科医师的重视，给临床提供一些帮助。

Advance on clinical diagnosis and treatment of external auditory cholesteatoma

ObjectiveExternal auditory canal cholesteatoma (EACC) is an uncommon disease of otorhinolaryngology. Early EACC lesions are not typical. Although EACC are benign tumors, they are biologically erosive. Early diagnosis and treatment of EACC are very important. Due to the relatively low incidence of EACC, there is no unified international standard for classification and staging of EACC. The treatment options of EACC mainly include conservative methods and surgical cleaning of cholesteatoma lesions. Therefore, more data need to be collected for a further comprehensive study. This paper systematically reviews relevant domestic and foreign literature, which summarizes and analyzes the etiology, pathogenesis and clinical characteristics of EACC in detail. This article will provide some help to arouse the attention of clinical otologists.
