[Cephalometry of Li people through 3-dimensional CT].
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.
