目的 :探讨陈旧性根治性乳突术腔填塞及外耳道后壁缺损的修复方法。方法 :采用耳后带蒂复合皮瓣移植 ,对 10例 (11耳 )行乳突根治术后 1～ 6年的患者 ,行陈旧性乳突术腔填塞及外耳道后壁缺损重建术 ,并同期行鼓室成形术。结果 :术后随访 3～ 30个月 ,全部患者乳突术腔消失 ,外耳道大小接近正常 ;术后干耳时间 2～ 3周 ,“根治腔病”症状明显好转 ,平均听阈下降 13.6 d B HL。结论 :本方法缩短了术后干耳时间 ,对乳突根治术后的“根治腔病”具有明显的治疗效果 ,有利于鼓室成形术。
Objective: To study the method of repairing the old radical mastoid cavity obstruction and the external auditory canal posterior wall defect. Methods: A total of 10 cases (11 ears) with mastoid protrusion 1 to 6 years after operation were treated with pedicled compound pedicle flap. The obstruction of the old mastoid cavity and reconstruction of the posterior wall of the external auditory canal were performed in the same period Tympanoplasty. Results: After 3 months to 30 months of follow-up, all patients had mastoid cavity disappeared and external auditory meatus size approached normal. After 2 to 3 weeks of dry ear surgery, the symptoms of “curative disease” were significantly improved and the mean hearing threshold decreased by 13.6 days. . Conclusion: This method shortened the postoperative period of dry ear, which has obvious curative effect on “Radical Cavity Disease” after radical mastectomy and is good for tympanoplasty.
