摘　　要：目的探讨粘膜下腭裂的产前超声诊断价值。方法对进行系统超声检查的中晚期妊娠胎儿使用经口裂斜冠切面及矢状切面对腭部进行常规筛查。产后经口腔专科医生检查。标本使用高频超声检查。结果 4305例中晚期妊娠胎儿共检出唇腭裂59例,其中粘膜下腭裂胎儿5例。声像图表现为硬腭正中连续中断,其上鼻中隔得以显示,软腭完整,动态观察软腭可折叠填充咽腔。引产后标本高频超声显示硬腭正中连续中断处表面粘膜完整,软腭正中线状收缩变薄。结论产前唇腭部常规筛查可以发现粘膜下腭裂。Objective To investigate the value of the prenatal ultrasound diagnosis in submucosal cleft palate.Methods Screening the fetus lip and palate routinely in second and third trimester of pregnancy using transoral oblique coronal section and median sagittal section of ultrasound.Then examined by a Dentists after birth.Specimens was checked by high frequency ultrasound.Results In 4305 cases of fetus in second and third trimester,59 cases of cleft lip and palate were detected,of which 5 cases were submucosal cleft palate fetus.Sonogram showed a interruption in the middle of hard palate,nasal septum can be displayed,the soft palate integrity,by dynamic observation we can find the soft palate could be collapsibly filled in pharynx.Specimens after abortion checked by high frequency ultrasound showed a interruption in the middle of the hard palate,there the mucosal surface was integral and the middle of soft palate was linearly contracting and thinning.Conclusion Submucosal cleft palate can be detected by the screening of lip and palate prenatal ultrasound examination routinely.
