In the article we present the experience of observing 27 children with bilateral stenosis or atresia of the external auditory canals with normal or slightly hypoplastic auricles. Three children had bilateral stenosis of the external auditory canals due to abnormal or premature fusion of the skull bones. The remaining 24 children had external auditory canals atresia in the bone part or throughout. 9 of them had a syndrome of deletion of the long arm of chromosome 18, 1 child had a mosaic form of Edwards syndrome. The average age at the time of diagnosis was 4 years 3 months. Atresia of external auditory canals in normal auricle is often caused by abnormalities of 18 pairs of chromosomes, and severe stenosis of external auditory canals can be observed in children with craniostenosis and other anomalies of the skull bones.
在本文中，我们介绍了对27例双侧外耳道狭窄或闭锁且耳廓正常或轻度发育不全儿童的观察经验。3例儿童因颅骨异常或过早融合导致双侧外耳道狭窄。其余24例儿童外耳道骨部或全程闭锁。其中9例患有18号染色体长臂缺失综合征，1例患有爱德华兹综合征的嵌合型。诊断时的平均年龄为4岁3个月。正常耳廓外耳道闭锁常由18对染色体异常引起，颅骨狭窄症和其他颅骨异常的儿童可出现严重外耳道狭窄。
