The management of a unilateral congenital atresia of the external auditory canal is nonuniform and debated. Various surgical approaches, timing, coordination with microtia repair, and variable hearing improvements all contribute to the debate regarding management of this entity. This paper outlines our craniofacial team approach to the congenital unilateral atresia and microtia in children. Selection criteria, timing of repair, coordination with microtia repair, surgical results, and pitfalls will be discussed. The results of surgery in 16 patients with unilateral congenital atresia of the external auditory canal and 2 children with bilateral atresia will be presented. Repair of the atresia was undertaken in children 5 years or older who had pneumatized mastoids and middle ears. Replacement of the malleus/incus complex with a partial ossicular reconstruction prosthesis improved closure of the air-bone gap. Drawbacks included meatal stenosis and deepithelization of the split thickness skin graft lining the external auditory canal. Repair of the unilateral congenital atresia is a demanding and challenging problem but one in which excellent results are achievable.
单侧先天性外耳道闭锁的治疗方法并不统一，存在争议。各种手术方式、手术时机、与小耳畸形修复的协同配合以及听力改善程度的差异，都导致了关于该病症治疗的争论。本文概述了我们颅面团队针对儿童先天性单侧外耳道闭锁和小耳畸形的治疗方法。将讨论选择标准、修复时机、与小耳畸形修复的协同配合、手术结果及陷阱。还将展示16例单侧先天性外耳道闭锁患儿和2例双侧闭锁患儿的手术结果。对于乳突和中耳已气化的5岁及以上儿童进行闭锁修复。使用部分听骨链重建假体替代锤骨/砧骨复合体可改善气骨导间距的闭合。缺点包括外耳道狭窄以及覆盖外耳道的中厚皮片去上皮化。单侧先天性外耳道闭锁的修复是一个要求高且具有挑战性的问题，但通过努力可取得优异的治疗效果。
