目的 :探讨胎儿唇腭裂的超声诊断及处理 .方法 :对近 3a发生的 3 8例胎儿唇腭裂进行回顾性分析 .结果 :3 8例胎儿唇腭裂中超声诊断 3 4例 ,诊断率为 89 4% ,其中唇裂 2 0例 ,唇裂合并腭裂 14例 .漏诊 4例 (唇裂合并腭裂 1例 ,单纯腭裂 3例 ) ,漏诊率为 10 6% .2例产前染色体诊断异常 ( 13三体及 18三体 ) .结论 :单纯唇裂及唇裂合并腭裂超声容易显示 ,单纯腭裂难以显示 .少数唇腭裂易合并染色体异常 .

To investigate the ultrasonographic diagnosis and disposal of fetal cheilognathoschisis. Methods: To analyze retrospectively the 38 cases of cheilognathoschisis which were diagnosed in the last 3 years. Results: In the 38 cases, 34 were diagnosed prenataly by ultrasond, including 20 simple cheiloschisis and 14 cheiloschisis combined with palatochisis. The accurate rate of sonographic diagnosis was 89.4%. The other 4 cases were missed diagnosed prenataly, 3 were simple palatochisis and 1 was cheiloschisis combined with palatochisis. 2 cases were diagnosed as anomaly of chromosome (21-trisomy and 18-trisomy). Conclusion: Simple cheiloschisis and cheiloschisis combined with palatochisis can be showed more easily than simple palatochisis by ultrasound. Owing to some cheilognathoschisis are combined with anomaly of chromosome, whether the pregnancy should be continued must be considered carefully once the fetal cheilognathoschisis is diagnosed.
