Abstract:
Objective To compare the three-dimensional eephalometric and three-dimensional CT measurements of adult zygomatic complex among a Sanjiang population.Methods 120 female natives of Sanjiang region from Chinese Han between 19 to 23 years of age (mean 21.4 years),were randomly selected from students of Jiamusi University.Three-dimensional cephalometric and CT measurements of the face and skull were taken,with reference to zygomatic size measurement by Prof.Qi Zuo-liang,for the comparative study, which included the upper,mid and lower facial width followed by the length,width and angle of malar process,and width of the facial bone.Statistical analysis was done with the obtained measurements.Results Three-dimensional CT analysis showed facial width ratio of 0.83 and 0.79 and skeletal facial profile width ratio of 0.81 and 0.77,respectively,when compared with three-dimensional cephalometric analysis that showed facial width ratio of 0.84 and 0.77.Both values showed no statistical significance (P>0.05).Conclusion Three-dimensional CT measurement as the same to three-dimensional cephalometric can be used in the diagnosis of prominent malar complex.
