摘要
目的了解面部轮廓老化的形态特征,为年轻化手术设计提供依据。方法采用计算机辅助三维CT重建技术,对20例老年人及20例青年人颅面形态结构做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)、耳前颏下点距(T-Gn)都明显高于青年组,而上颌高(N-Sd)和上面宽(Ft-Ft,T-T)则明显低于青年组。结论随着年龄的增长,面部宽度、眶上嵴突及颅面深度有随之增加的趋势,而面部垂直高度有随之降低的趋势。
Objective To study the morphological characteristics of craniofacial contour in ageing. Methods Craniofacial morphology was examined in a sample of 20 young men and 20 old men. 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 men, old men in- creased with midface （Zy-Zy）, lower face （Go-Go）, supraorbital projection （Fb-Sr, T-So）, midface depth （N-Po）, and lower facial depth （T-Gn）, and decreased with maxillary height （N-Sd） and upper facial width （Ft-Ft, T-T）. Conclusion Facial width and depth and supraorbital projection tend to be increased and facial height decreased with ageing.
