摘要
目的 探讨超声检测下颌骨发育的意义及其临床价值。方法 对 2 0 4例胎龄 12~ 40周胎儿下颌骨前后径和左右径进行超声检测。对 13 9例高危胎儿进行下颌畸形的筛选。结果 胎儿下颌骨前后径和左右径与孕天呈高度相关性 ( r分别为 0 .917,0 .898,均 P <0 .0 1)。检测 13 9例高危胎儿 ,诊断小下颌畸形 3例。
Objective To study the significance of ultrasonography for the fetal mandible development and its clinical value.Methods The anteroposterior and laterolateral diameter of the mandible were measured in 204 normal fetuses between 12 and 40 weeks gestation and plotted against gestational age.Another examinations for mandible malformations were analyzed in 139 cases with high risk.Results The anteroposterior and laterolateral diameter of mandible were linearly correlated with gestational age (r 1= 0.917 ,r 2= 0.898 ,P< 0.01 ).By the standard and means,3 cases of micrognathia were diagnosed in 139 cases with high risk.Conclusions Fetal mandible malformations could be diagnosed prenatally by examing the anteroposterior and laterolateral diameter of fetal mandible.
