目的探讨产前超声诊断11~14孕周胎儿唇腭裂的方法和价值。方法回顾性分析产前超声诊断为胎儿唇腭裂(11~14孕周)的病例资料,对其超声特点进行分析,探讨其诊断要点。结果 22例中经引产后尸检证实17例,出生后随访证实1例,失访3例,误诊1例。22例在经上颌牙槽突弓轴平面均显示上唇连续性中断及上牙槽“C”形曲线连续性中断,18例在颜面正中矢状切面未显示腭中缝区的强回声带,17例在鼻后三角冠状切面显示下方连线中断。结论产前超声对检出11~14孕周胎儿唇腭裂具有极重要的诊断价值。
Objective To investigate the method and value of prenatal ultrasound in the diagnosis of fetus cleft lip and palate during 11 ~ 14 gestational weeks. Methods A retrospective analysis of prenatal diagnosis of fetal cleft lip and palate (11 to 14 gestational weeks) case data, the characteristics of their ultrasound were analyzed to explore the diagnosis points. Results Of 22 cases, 17 were confirmed by autopsy after autopsy, 1 case was followed up after birth, 3 cases were lost to follow-up, and 1 case was misdiagnosed. Twenty-two cases showed discontinuity of upper lip continuity and continuity of upper alveolar “C” -shaped curve in the plane of maxillary alveolar arch axis. Echogenic zone of palatal midfacial region was not observed in 18 cases of median sagittal section, 17 cases in the nasal coronal triangular coronal plane showed the bottom of the connection interrupted. Conclusion Prenatal ultrasound is of great diagnostic value in the detection of cleft lip and palate of 11-14 gestational weeks.
