目的观察分析听骨链与外耳道先天性畸变的相互关系。方法回顾性总结100耳先天性畸变的资料,分耳道骨性闭锁(Ⅰ型)、耳道狭窄(Ⅱ型)和单纯中耳畸形(Ⅲ型)三组。用锤砧镫骨畸变率和听骨胚源发生障碍率进行归纳。结果Ⅰ型患者锤砧镫骨畸变...目的观察分析听骨链与外耳道先天性畸变的相互关系。方法回顾性总结100耳先天性畸变的资料,分耳道骨性闭锁(Ⅰ型)、耳道狭窄(Ⅱ型)和单纯中耳畸形(Ⅲ型)三组。用锤砧镫骨畸变率和听骨胚源发生障碍率进行归纳。结果Ⅰ型患者锤砧镫骨畸变率分别为81.8%、93.9%和30.3%,Ⅱ型为75%、83.3%和75%,Ⅲ型为36.4%、83.6%和89.1%,卡方检验三组无显著性差异(P>0.05)。胚源分类Ⅰ、Ⅱ型以第一和第二鳃弓混合型发育障碍为主,Ⅲ型以第二鳃弓占多数,三组卡方检验有显著性差异(P<0.05)。100耳病例术后63耳听力提高,其中>20 dB 41耳,气骨导闭合12耳。结论以外耳道畸变程度结合听骨胚源发生学,可发现:Ⅰ型以锤砧骨畸形为主,镫骨少见,Ⅱ型锤砧镫骨畸形基本相等,Ⅲ型以砧镫骨畸形为主,锤骨少见。展开更多

ACC can occur as an isolated condition or in the presence of the other congenital anomalies. Here we describe a case of a 1-day-old baby boy with an isolated ACC of the left foot, with no family or siblings positive disease history. The patient was managed by both conservatively and surgically until the defect has formed scar tissue 5 months later.展开更多
