摘要
目的探讨胆脂瘤型中耳炎手术中必须去除外耳道后壁时以软性后壁作为替代的手术适应症和疗效。方法回顾性分析91例患者的手术方法及随访3～12个月的效果,根据病变轻重及范围,选择开放式乳突根治术、完璧式乳突根治术、乳突根治术后软性外耳道后壁重建术3种术式,进行干耳率、并发症、听力提高3种指标的比较。结果软性外耳道后壁重建术组干耳率(91.7%)介于放式乳突根治术(97.5%)和完璧式乳突根治术(88.9%)之间,听力提高与完璧式乳突根治术组比较无差异。结论软性外耳道后壁重建术为开放式乳突根治术和完璧式乳突根治术的中间术式,能同时满足尽量清除病变和提高听力2项要求。
Objective To evaluate the value of ear canal wall reconstruction with soft tissues in mastoidectomy for cholesteatoma. Methods Surgical techniques, treatment outcomes and follow-up results （3 to 12 months） in 91 patients who received mastoidectomy were reviewed. Radical mastoidectomy or mastoidectomy with either posterior ear canal wall preservation or reconstruction using soft tissues were chosen for these cases based upon the extent and severity of the lesion. The dry ear rates and post-operative complications were compared among the three surgical techniques. Results The dry ear rate in ear canal wall reconstruction with soft tissues was 91.7%, lower than that in radical mastoidectomy （97.5%） but higher than that in mastoidectomy with posterior wall preservation （88.9%）, while hearing outcomes were similar to mastoidectomy with posterior wall preservation. Conclusion Soft tissue ear canal wall reconstruction is an intermediate technique between radical surgery and complete posterior wall preservation and can be considered when both lesion eradication and hearing reconstruction are important.
