摘要目的 探讨应用二维和三维超声检查胎儿面部结构的临床价值.方法 应用多普勒超声诊断仪对孕16～42周1805例胎儿进行二维、三维检查,观察胎儿面部结构,并与产后或引产后结果相比较.结果 1805例中,孕23～35周后应用二维及三维超声观察胎儿颜面部结构,显示率差异无统计学意义(93.1%、95.1%,P0.05).孕23周前三维显示率明显高于二维(84.8%、69.6%,P<0.01),孕35周后二维显示率略高于三维,但差异无统计学意义(90.4%、88.7%,P0.05).结论 选择最佳时机检查胎儿面部结构,可以提高诊断准确率,利于优生优育.

abstractsObjective Study on the clinic value of the application of two-dimensional and three-dimensional sonography on observing the fetal facial structure. Methods Applying Voluson 730 three-dimensional probe surface imaging mode and two-dimensional probe to make sonography on 16～48 weeks fetus in 1805 cases, emphasized on observing the fetal facial structure, saving the image information, making three-dimensional reconstruction and comparing the result of post partum and the result after induction of labor. Results In 1805 cases, applying two-dimensional and three-dimensional sonography to observe the facial structure of the fetus of 23～35 weeks, the display rate is 93.1% and 95.1% respectively, and there is no obvious difference between the two modes. The three-dimensional is higher than two-dimensional for the fetus less than 23 weeks, with the display rate 69.6% and 84.8% respectively, and the two-dimensional is a bit higher than three-dimensional for the fetus more than 35 weeks, with the display rate 90.4% and 88.7% respectively. One cleft lip case is excluded. Conclusion As long as mastering the optimum examination time and operation skill, there is no obvious difference between the display rate of two-dimensional and three-dimensional sonography on observing the fetal facial structure, the two modes can be complementary in the work to improve the accuracy of the diagnosis and be favorable for the prepotency.
