　　［摘要］目的：了解颅面骨骼轮廓老化的形态特征。方法：采用计算机辅助三维重建技术对20名老年人及20名年轻人颅面骨骼形态结构作立体定量的比较分析。结果：老年组在中面部（Zy-Zy）、下面部（Go-Go）、眶上嵴突（Fb-Sr，T-So）、头长（N-Po）都明显高于年轻组，而下颌高（Id-Gn）则明显低于年轻组。结论：随着年龄的增长，面部宽度、眶上嵴突及头长有随之增加的趋势。

　　Abstract: Objective To study the morphological characteristics of craniofacial contour in aging. Methods Craniofacial morphology was examined in a sample of 20 young people and 20 old people.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 Compared with the young people, old people increase in midface width(Zy-Zy) ,lower  face width(Go-Go),supraorbital projection (Fb-Sr),midface depth(N-Po),and decrease in lower facial height(Id-Gn). Conclusion  The results suggest that facial width and depth,supraorbital projection increase with  age.
