外耳道胆脂瘤诊疗进展

Advances in Diagnosis and Treatment of External Auditory Canal Cholesteatoma

外耳道胆脂瘤(external auditory canal cholesteatoma,EACC)是一种少见的耳鼻喉科疾病,临床症状不具有特征性,早期病变容易误诊、漏诊,其病因和发病机制尚未完全明了,国际上尚无统一的分型和分期,治疗原则为保守或手术清理胆脂瘤组织,术式选择多样。本文对EACC的病因、发病机制、分型分期和诊断治疗进展做一综述,以期给临床提供一点帮助。

External auditory canal cholesteatoma(EACC) is a rare otologic disease, which is often misdiagnosed because of its often non-characteristic clinical presentations. Its etiology and pathogenesis remain unclear, and there are no unified international classification or staging standards. Principle treatment is conservative or surgical removal of EACC, with surgical techniques vary considerably. This paper reviews latest advances in the etiology, pathogenesis, classification/staging, diagnosis and treatment of this condition, in a hope to faciitate clinical management.
