摘要
目的：探讨乳突进路行外耳道闭锁再造中，联合上鼓室外侧壁、外耳道后壁重建技术的疗效。方法：搜集2011年1月至2014年1月入住我科25例（25耳）外耳道闭锁患者，均采用乳突进路联合上鼓室外侧壁、外耳道后壁重建术式，术后6周采用耳模扩展9－12月，术后随访1～3年。分析疗效指标：干耳率、耳道再闭锁率、听力提高程度、术后并发症。结果：25例患者完全达到干耳；3例患者因瘢痕再狭窄；平均听力提高＞40dB 有8例，平均听力提高＞30dB 有11例，平均听力提高＞20dB 有6例。结论：采用乳突进路联合上鼓室外侧壁、外耳道后壁重建术式行外耳道闭锁再造，具有手术解剖标志清楚、安全、疗效可靠等优势。
Abstract
objective:to investigate the curative ef ect.Of the mastoid into the road line plane atresia reengineering,combined drum on the outside wal ,external auditory canal wal re-construction.Methods:col ected 25 cases (25 ears)patients with external auditory canal atresia from January 2011 to January 2014 in our department,adopted mastoid approach combined drum on the outside wal ,external auditory canal wal reconstruction surgery,the molds were extending 9 -12 month after 6 weeks.fol owed up of 1 ~3 years.Analysis of curative ef ect:the dry ear rate,the ear to closure rate,improve the degree of hearing,the postoperative complications.Results:25 cases with completely dry ear;Three patients with scar restenosis;an average improve-ment of hearing >40 db in 8 cases,an average improvement of hearing >30 db in 11 cases,an average of hearing improve >20 db in 6 cases.Conclusion:There were the advantages of sur-gical anatomy mark clear,safe,reliable curative ef ect by the mastoid approach combined drum on the outside wal ,external auditory canal wal reconstruction operation in the external auditory canal atresia after the construction.
