Facial pictures of them were taken by 3dMD photography and traditional photography respectively, photographing time was recorded. Facial measurements' quality data were analyzed by SPSS 16. 0. Results: The photographing time of the 3dMD group and traditional photographic group was(14. 99 ± 1. 34) s and (45. 33 ± 7. 75) s respectively(P< 0. 05); there was no significant difference between the 2 groups in the quality scores. Conclusion: The clinical use of 3dMD in patients can save the operation time and can get similar by the use of results traditional radiography.
