目的探讨外伤性外耳道狭窄或闭锁的诊断和治疗方法。方法回顾性分析1991年7月至2007年12月期间19例因外伤所致的外耳道狭窄或闭锁的临床资料。结果19例均行外耳道成形术,随访1～12年,15例外耳道较宽大,听力正常。有4例术后一个月后又狭窄:其中3例为瘢痕体质,1例经长期用碘仿纱条填压扩大而愈,2例给予填压扩大后又有狭窄的趋势,采用硅胶管扩张3个月治愈;1例再次手术治愈。结论早期诊断外伤性外耳道狭窄或闭锁非常重要,外耳道成形术是一种有效的手段,应根据狭窄部位和程度的不同情况采取相应的处理方法,术后需长期随访。
Abstract：Objective To study management of traumatic stenosis and atresia of the external auditory canal.Methods Nineteen cases of traumatic stenosis or atresia of the external auditory canal treated between July 1991 and December 2007 were retrospectively analyzed.All 19 cases were treated with external auditory canal plastic surgery and followed for 1 to 12 years.Results Adequate ear canal sizes were maintained in 15 cases with normal hearing at their last follow ups.Recurrent stenosis occurred in 4 cases,of which 1 was treated with iodoform gauze packing,,2 with silastic tubes,and 1 with revision surgery.Conclusion External auditory canal plastic surgery is effective in treating traumatic stenosis and atresia,preferably in the early stage.
