目的利用三维CT研究海南黎族人颅面骨的结构及特征.方法 CT扫描和三维重建能客观显示两点间距离及三点间角度,并可将三维影像放大增加精确度,通过对80名黎族成年人颅面骨进行三维测量分析,并与汉族人进行比较.结果黎族人颅面骨数据在性别间存在较大差异,与汉族人相比,黎族人具备眶宽、颅头宽及面阔的面部特征.结论 CT测量及三维重建可准确表述颅面三维结构特征,而颅面骨数据为黎族人进行颌面部整形手术提供了客观参考依据.

Objective To investigate the skull characteristics of the Li people in Hainan through 3-D CT.Methods CT scan and 3-D reconstruction are very helpful for the cephalometry including the distance and angle measurement.The image can also be enlarged to make the measurement more precisely.80 Li volunteers underwent the cephalometry through 3-D CT.The data were analyzed and compared with those an people.Results The results showed difference between the genders of Li people.Compared with Han people,Li people has their own facial characteristics,such as wider face and wider orbital distance.Conclusions Cephalometry through 3-D CT can show the skull characteristics precisely.The data in this study has great significance in craniomaxillofacial surgery and ethnology.
