胎儿唇腭裂的超声诊断价值

Diagnostic Value of Color Doppler Ultrasound in the Cleft Lip and Palate Malformation in Fetus

目的:探讨胎儿正常唇腭部与唇腭裂畸形的超声检查方法、最佳检查时机及声像图特征,旨在提高产前超声对唇腭裂畸形的确诊率。方法:利用超声对6748例孕16～41周的孕妇常规进行胎儿口唇部观察。结果:6748例中有6254例胎儿口唇部能清晰显示,唇裂17例,检出率88.1%,漏诊2例。结论:孕18～32周是超声检查胎儿唇腭裂畸形的最佳时机。二维声像图诊断唇裂的直接征象为胎儿唇部回声失落,鼻小柱向健侧移位,患侧鼻翼内陷是唇腭裂的常见声像图表现。超声是筛选和诊断胎儿唇腭裂畸形的重要手段。

Objective：To evaluate the ultrasonography appearance of the fetus cleft lip and palate malformation and choose the best checking time to improve the diagnostic accuracy for cleft lip and palate malformation.Methods：6748 pregnant women of 16～41 odd weeks gestation were examined by ultrasonography.Results：17 fetuses with cleft lip and cleft palate were found.2 cases were missed.The detect rate is 88.1%.Conclusion：The 18～32th gestational week are the best time for ultrasound examination for cleft lip and palate.The interruption of fetus＇ upper lip is the main symbol of eleft lip The disappearance of upper lip node,nasoseptal displacement and the collapse of nose wing are the usual displays of cleft lip and cleft palate.
