Objective: To study the characteristics of the craniofacial bone in Zhuang nationality by 3-D-CT. Methods: The craniofacial bones of 100 Zhuang were scanned via spiral CT, and three-dimensional reconstruction and three-dimensional measurement were performed. All data were compared with those of Han people. Results: The results showed a difference between the genders of Zhuang people. Compared with Han people, Zhuang people had their facial characteristics,such as wider orbital, wider and higher cheek bone, while nasal bone was wider, shorter and lower. The middle part of the face was wider and shorter. Conclusion: The data of the craniofacial bone of Zhuang people can be measured by spiral CT scan and three-dimensional reconstruction, which may offer reference for the study on anthropology and nationality and provide information for the plastic operation of the craniofacial bone in Zhuang people.%目的:利用CT研究壮族正常成人颅面骨的结构特征.方法:通过对100名壮族成人行头颅CT扫描,行三维重建后测量,获得颅面骨相关数据,与汉族人相比较.结果:壮族正常成人颅面骨男、女间有性别差异,与北方汉族人相比,壮族人具有眶宽及颧骨宽大、突出,而鼻骨宽、短、低平,中面部宽、短等特征.结论:头颅CT三维重建及三维测量,可获得壮族正常成人颅面骨有关数据,对人类学和民族学有意义,而且可为壮族人面部整形手术提供治疗参考.
