摘要
目的探讨采用耳内镜技术治疗外耳道胆脂瘤的手术方法和疗效。方法回顾性分析2006—2008年采用耳内镜技术治疗30例外耳道胆脂瘤患者的临床效果。30例患者中传导性聋患者26例,言语频率平均气导听阈为35（s=6.3）dB HL;4例为混合性聋,言语频率平均气导听阈为65.4 dB HL,平均骨导听阈为45.5dB HL。结果临床资料完整并经治疗后随访6~12个月,30例患者术后气导听阈均有较大提高,言语频率平均气导听阈提高15~23 dB HL。无1例手术后并发症。随访1~3年未见复发。其中治愈27例（90%）,好转3例（10%）,总有效率为100%。结论颞骨薄层CT扫描对术前诊断有很好的指导意义。耳内镜对治疗外耳道胆脂瘤具有微创、快捷、预后佳的特点。
Objective To study the application of otoendoscopic treatment of cholesteatoma associated with external acoustic meatus. Methods Thirty cases of external acoustic meatus cholesteatoma between 2006 and 2008 were treated by otoendoscope.Twenty-six of 30 cases were conductive hearing loss with the average hearing threshold of 35（s=6.3） dB HL,4 of 30 cases were sensorineural hearing loss with the average air conductive hearing threshold at 65.4 dB HL,and average bone conductive hearing threshold ad 45.5dB HL respectively. Results The hearing loss of the most patients improved to a certain extent.All the cases were followed up from 1 year to 3 years,and no recurrent cases were found.Conclusions High-resolution temporal bone CT scan can help identify the primary lesion and determine the range of the pathological changes,and otoendoscopic treatment is a simple and minimally invasive technique for cholesteatoma associated with the external acoustic meatus.
