Surgical correction of the severely stenosed or atretic external canal still remains a difficult surgical challenge. As more and more techniques are described, it is apparent that the main thrust and emphasis is to prevent late cicatrization or stenosis. The essential principles are to create a wide canal and cover as much raw surface as possible with skin, preferably full-thickness and with an intact blood supply. The following technique, using dual flaps, has been used successfully in 10 consecutive problem ears with unusual underlying pathologies. With follow-up ranging from seven months to four years, there have been no cases of restenosis to date.
严重狭窄或闭锁外耳道的外科矫正仍然是一项具有挑战性的外科手术。随着越来越多的技术被描述，显然主要的重点是预防晚期瘢痕形成或狭窄。基本原则是创建一个宽阔的外耳道，并尽可能用皮肤覆盖更多的创面，最好是全层皮肤且血供完整。以下使用双皮瓣的技术已成功应用于连续10例存在特殊潜在病变的疑难耳。随访时间从7个月到4年不等，迄今为止尚无再狭窄病例。
