侵及中耳的III期外耳道胆脂瘤的手术方法探讨

目的探讨侵及中耳的Holt III期外耳道胆脂瘤的手术方法。方法回顾性分析35例侵及中耳的III期外耳道胆脂瘤患者的临床资料，35例患者中男15例，女20例；年龄15~66岁，平均年龄45岁。所有患者均在全麻显微镜下经外耳道入路单纯行外耳道胆脂瘤切除术。结果术后随访6个月以上，所有患者均无复发或外耳道狭窄等并发症，纯音测听（23.3±1.3）dB，听力恢复至正常水平。结论临床中可以选择单纯行外耳道胆脂瘤切除术治疗III期外耳道胆脂瘤，但需要密切随访。

Surgical treatment of Holt III external auditory canal cholesteatoma invading the middle ear

ObjectiveTo discuss the surgical method for Holt III external auditory canal cholesteatoma (EACC) invading the middle ear.MethodsClinical data of 35 cases with Holt III EACC undergoing surgical treatment in our department were analyzed retrospectively. Of them, 15 were male and 20 were female. Their age ranged from 15 to 66 years old with an average of 45. Microscopic resection of EACC was performed via external auditory canal approach in all the 35 patients.ResultsPostoperative follow up for more than 6 months showed neither recurrence nor stenosis of external meatus. All the patients restored their hearing to normal with an average threshold of (23.3±1.3) dB by pure tone audiometry.ConclusionSimple resection of cholesteatoma via external auditory canal approach is feasible for the treatment of Holt III EACC, but close postoperative follow up is essential.
