目的探讨外耳道胆脂瘤(EACC)的临床特点及治疗方法。方法回顾分析经手术治疗及病理检查确诊为EACC患者17例临床资料,依分期不同采用不同手术方式。结果17例均于术后4～8周外耳道内或乳突腔创面上皮生长良好,耳道宽敞,听力完全恢复4例,较术前提高20～40dB 8例,无变化5例,随访6～24月无复发。结论EACC多为自发性,对耳和周围的软组织及骨组织具有破坏性,应依病变程度选择手术方式,彻底清除胆脂瘤和死骨,防止残留和复发。
Objective To investigate the clinical features and treatment of external auditory canal cholesteatoma (EACC). Methods Retrospective analysis of 17 cases of EACC patients diagnosed by surgery and pathological examination clinical data, according to different stages with different surgical methods. Results All the 17 cases were well developed in the external auditory meatus or mastoid epithelium epithelium 4 ~ 8 weeks after surgery. The ear canal was spacious and the hearing was completely recovered in 4 cases, 8 cases more than 20 ~ 40 dB, 5 cases unchanged and 6 ~ No recurrence in 24 months. Conclusions EACC is mostly spontaneous. It is devastating to soft tissues and bone tissues in the ear and the surrounding. EACC should be operated according to the degree of lesion, and the cholesteatoma and sequestrum should be completely removed to prevent the residual and recurrence.
