三维超声表面成像对胎儿颜面少见畸形的诊断价值

Diagnostic value of three-dimensional ultrasonographic surface rendering on the rarely fetal facial abnormalities

目的探讨三维超声表面成像对胎儿颜面部少见畸形的诊断方法和价值。方法对11300例2011年3月至2012年3月孕16～37周的产妇常规行胎儿颜面部结构的三维超声成像。结果全部胎儿中发现颜面部少见畸形34例,检出率为0.3%,其中包括先天性白内障3例,胎儿小眼畸形7例,无眼畸形(病理为隐眼畸形)1例,单鼻孔11例,无鼻3例,口腔寄生胎3例,颜面部咸涎腺细胞瘤1例,外耳畸形5例,均经引产或出生后证实。结论三维超声能直观显示胎儿的颜面部结构,是诊断胎儿颜面部畸形的首选方法,产前进行常规的超声检查具有重要的临床意义。

Objective To explore the value of three-dimensional ultrasonographic diagnosis on the fetal facial rarely abnormalities. Methods In 11300 pregnant women of 16 ～ 37 gestational weeks from March 2011 to March 2012, the fetal faces were regularly imaged by three-dimensional ultrasonography. Results 34 cases with facial deformity were detected in all cases, with the detection rate of 0.3%. for those cases, 3 were congenital cataract, 7 microphthalmus, 11 single nostriland, 3 arrhinia,3 parasitus in oral cavity, 1 facial salivary gland cytoma,5 deformity of external ear, 1 anophthalmia. The detection results were finally confirmed by odinopoeia or birth. Conclusions Three-dimensional ultrasonography can directly display the fetal facial structures, and is the first choice in the diagnosis of fetal facial abnormalities. Prenatal regular ultrasound has important clinical significance.
