Supraorbital ridge contour by multi-slice helical CT:an anthropometric analysis

目的 初步了解中国人眉弓的正常形态 ,为眉弓轮廓的美容改型提供依据。方法 采用计算机辅助三维CT重建技术 ,对 4 0例正常人眉弓形态结构做立体的定量测定与分析。结果 男性在额宽、额高、颅长、眶上嵴突、眶高、上下眶缘之差及耳前鼻根距均明显大于女性 (P <0 .0 5 ) ,而青年组在前额高、颅长、眶上嵴突、前额角也明显小于老年组 (P <0 .0 5 )。结论 眉弓轮廓存在性别差异 ,并有随年龄增大而前突的趋势。

Objective To understand the morphology of supraorbital ridge and toprovide basis for aesthetic surgery. Methods Forehead morphology was examined in 40 adults (20 men and 20 women). By multi-slice helical CT, a computer reconstruction technique was used to produce three dimensional images and 3-D reconstruction data were analyzed quantitatively. Results Ft,-Ft, V N, N-Op, Fb-Sr, Zm-So, Dbr, Pra-N in male were significantly larger than those in female, and V-N, N-Po, Fb-Sr, FA in youth men were significantly smaller than those in old men. Conclusion There is a difference of forehead between male and female. Projection of supraorbital ridge increases with age.
