先天性外耳道闭锁成形术后狭窄或再闭锁10例

Surgical management for stenosis or atresia after operations for congenital external atresia in 10 cases

目的探讨先天性外耳道闭锁成形术后狭窄或再闭锁的处理方法及效果。方法对10例(耳)先天性外耳道闭锁成形术后出现狭窄或闭锁的患者行再次手术,选取耳道后方作切口,切除狭窄或闭锁的瘢痕,扩大外耳道,术腔植皮,7耳同期鼓室成形。结果10耳中2耳外耳道出现再狭窄,经局部注射激素,纱条压迫后缓解,术后语频听力提高15 dBHL者7耳,听力无改变3耳。结论先天性外耳道闭锁成形术后狭窄或再闭锁病例,再次手术仍是有效的方法,并可同期行鼓室重建。

Objective To explore the surgical management for stenosis or atresia following operations for congenital external atresia and its effect.Methods 10 cases of stenosis or atresia which had received operations for congenital external atresia were enrolled in this study.In the second operations,an endaural incision was done and scar tissues were cut away to extend the external canal,skin grafting was transplanted to the new canal,and also tympanopalsty was simultaneously done in 7 ears.Results 2 cases had re-stenosis and were alleviated after local rejection of hormones and local packing.PTA of 7 cases decreased 15 dBHL and of the other 3 cases had no improvement.Conclusion Re-operation for stenosis or atresia after operations for congenital external atresia is effective and tympanoplasty can be simultaneously done.
