Abstract:
Objective To discussion the value of palate standard section in prenatal ultrasound diagnosis of isolate cleft palate,and summarize the two-dimensional ultrasound characteristics of isolate cleft palate.Methods Two-dimensional ultrasound was performed in 1 8 073 fetuses during 1 8 to 40 gestational weeks of pregnancy.Fetal palate structure were scanned through the oral cleft,the cheek,the neck part,and the standard sagittal section,transverse section and coronal section were obtained to diagnosis cleft palate. The results were compared with labour or postpartum findings.Results In 1 8 073 cases,20 cases of isolate cleft palate,1 9 cases were diagnosed as fetal isolate cleft palate by prenatal ultrasonography,of which 1 8 cases were correctly diagnosed,1 case was misdiagnosed,1 case was missed diagnosed.The sensitivity, specificity,accuracy of prenatal ultrasound detection were 95%,100%,95%,respectively.The ultrasonic characteristics of isolate cleft palate:lack of crack were located in the midline,soft cleft palate was shown as the midline of soft palate interrupted,short of crack was“><”,“‖”,“/\”shape,hard cleft palate was shown as the midline of hard palate interrupted,short of crack was open back“V”or“U”shape.Conclusions The palate standard section has high value in prenatal ultrasound diagnosis of cleft palate,which can assess fracture morphology,length,width,direction and involving range.
