目的：探讨三维超声OmniView在早孕期诊断胎儿鼻骨缺失中的应用价值。方法选取300例早孕期来我院行常规超声检查的孕妇，按胎儿头臀径分为四组，分别为45~54 mm组65例、55~64 mm组74例、65~74 mm组85例、75~84组76例，应用二维及三维超声OmniView对其鼻骨进行观察及图像分析，对比各组间鼻骨的显示率，并重点对鼻骨缺失者进行图像分析。结果①各组三维超声OmniView对胎儿鼻骨的显示率均高于二维超声，除55~64 mm组(显示率相同)外，各组两者比较差异无统计学意义(P>0.05)；②三维OmniView对胎儿鼻骨的总显示率稍高于二维超声，但两者比较差异无统计学意义(P>0.05)。其中6例二维超声在颜面正中矢状面未探及鼻骨，三维超声OmniView可通过颜面部正中矢状面描画解剖线，获取鼻后三角冠状切面和其相垂直的横断切面，显示了胎儿鼻骨。另外7例二维超声及三维OmniView均未显示胎儿鼻骨，诊断为鼻骨缺失。结论三维超声OmniView操作简单，能在二维超声的基础上提供更多鼻骨的诊断信息，减少对操作者技术和经验的依赖，为妊娠早期诊断鼻骨缺失提供了新的思路和方法，是二维超声检查的重要补充。

Objective To investigate the clinical application value of OmniView (a new three-dimensional ultra-sound technology) in the diagnosis of absence of nasal bone in early pregnancy. Methods Three hundred pregnant wom-en who underwent routine ultrasound examination in our hospital were enrolled in the study, which were divided into four groups according to the fetal crown rump length:45~54 mm (65 cases), 55~64 mm (74 cases), 65~74 mm (85 cases), and 75~84 mm (76 cases), respectively. The nasal bone was observed and analyzed of by applying two-dimensional ultra-sound and three-dimensional ultrasound with OmniView. The display rates of nasal bone were compared between groups, and the images of absence of the nasal bone were analyzed. Results ①The display rate of each group of OmniView for fetal nasal bone was slightly higher than that of two-dimensional ultrasound (except 55~64 mm group, with the same display rate), but there was no statistically significant difference (P>0.05).②The total display rate of OmniView on fetal nasal bone was slightly higher than that of two-dimensional ultrasound, with no statistically signifi-cant difference (P>0.05). For two-dimensional ultrasound, 6 cases does not show the fetal nasal bone in the median sagittal plane on the face. However, for the 6 cases, OmniView can draw the anatomical lines on referenced facial sag-ittal plane, obtain the retronasal triangle coronal and its perpendicular to the axial plane, then display the fetal nasal bone. Besides, 7 cases did not display the fetal nasal bone in both two-dimensional ultrasound and OmniView, which were diagnosed as nasal bone a bsence. Conclusion Three dimensional ultrasound with OmniView has the advan-tage of simple operation, and can provide more diagnostic information of the nasal bone based on two-dimensional ul-trasound, as well as reduce dependence on operator's skill and experience. It provides a new idea and method for the early diagnosis of absence of nasal bone and serves as an important supplement of two-dimensional ultrasonography.
