摘　　要：目的 :探讨三维超声成像在评价中晚期妊娠胎儿面部结构中的临床应用价值。方法 :利用 Voluson5 30 D三维超声成像仪对 30例孕 18～ 40周的胎儿面部结构进行三维超声重建。结果 :2 3例 (76 .7% )胎儿能获得满意的面部三维图像。 8例二维超声不能判断胎儿上唇正常与否和 4例有分娩唇 (腭 )裂胎儿病史的病例通过三维超声成像排除了胎儿面部畸形的存在。三维超声表面成像可直观、清晰地识别胎儿的眼、鼻、上唇、下颌等面部结构及其相互间位置关系 ;透明成像能显示颅面部骨性结构 (顶骨、上颌骨、下颌骨等 )。而二维超声只能显示上述结构的断面图像。结论 :三维超声成像可提供较二维超声更为丰富的关于胎儿面部的诊断信息 ,是二维超声有益的补充 ,将在胎儿的产前诊断中发挥重要的作用。Objective:To evaluate the clinical value of visualizing the fetal face with three dimensional ultrasonography(3DUS).Methods:Thirty fetuses in second and third trimester were studied by using the imaging system of Voluson 530D. The methods included surface mode, transparent mode and multiplanar mode.Results:Satisfactory 3D images of the fetal face were obtained in 23(76 7%) cases. 3D sonograms clearly showed the continuity and anatomic spatial relationship of the facial structures, such as the eyes, noses and lips. The bony structures of the face were identifiable on the 3D sonograms when rendered by transparent mode. On the contrary, two dimensional ultrasonography (2DUS) could not present the face as a coherent structure.Conclusion:3DUS can provide more information about fetal face than 2DUS and enhance the scanner′s diagnostic confidence. It is a beneficial supplement to 2DUS, and is believed to possess a great role in prenatal diagnosis.
