炎症后获得性外耳道闭锁是慢性中耳炎或复发性外耳炎的一种相对罕见的后果，年发病率为每10万名居民0.6例。本文报告了27年来手术治疗这种疾病的53耳的初步和远期结果。描述了围手术期的表现，并概述了所应用的外科技术，其中6例为双侧受累。男女之比为1：2，中位年龄46岁，中位随访期5年(4个月~13年)，11%发生复发性闭锁。建议早期手术，因为闭锁后胆脂瘤的发生率为9%。解除闭锁后，90%的病例气骨间隙一期闭合在20分贝以内，听力有显著改善。
Postinflammatory, acquired atresia of the external auditory meatus is a relatively rare consequence of chronic otitis media or recurrent external otitis with an annual incidence of 0.6 cases per 100,000 inhabitants. Primary and late results after operative treatment of this condition in 53 ears over 27 years are presented. Perioperative findings are described, and an outline of applied surgical technique is given, Six patients had bilateral involvement. The male-to-female ratio was 1:2, median age at surgery was 46 years, and the median follow-up period was 5 years (range, 4 mo to 13 y), In 11% of the cases, recurrent atresia developed. Early operation is recommended, because cholesteatoma behind the atresia was found in 9%. Hearing improvement has been considerable after removal of the atresia with primary closure of air-bone gap within 20 dB in 90% of the cases.
