目的通过MRI和VGStudio MAX 2.2软件对中国汉族成人颅面相关径线进行测量,并分析其与性别、年龄、身高以及体重的关系。方法按颅面标志点设定4条径线。A径线:在正中矢状面上颏下点至头顶点的最大直线距离;B径线:在正中矢状面上发际点至后头点的最大直线距离;C径线:在水平面上左、右外眼点间的最大直线距离;D径线:在冠状面上左、右侧颧点间的最大直线距离;用VGStudio MAX 2.2软件对MRI图像数据进行三维重建,直接用软件的测量工具对颅面的相关径线进行测量,并用SPSS 16.0进行分析。结果 A、B、C、D径线的均值分别为(237.54±8.63)mm、(173.07±8.28)mm、(89.58±4.46)mm、(127.34±8.16)mm,与性别有着显著性差异(P<0.01);其中A、C、D径线与身高,A、D径线与体重,C径线与年龄,均存在明显的直线相关关系。结论中国汉族成人颅面径线A、B、C、D均存在明显的性别差异;且A、C、D径线与身高,A、D径线与体重,C径线与年龄,均存在明显的直线相关关系。
Objective To measure the craniofacial relative diameter of Chinese Han nationality by MRI and VGStudio MAX 2.2 software and analyze its relationship with gender, age, height and weight. Method According to the craniofacial marker points set 4 diameter lines. A diameter: the maximum straight line distance from the submental point to the top of the head on the median sagittal plane; B-line: the maximum straight line distance from the onset point to the posterior point on the median sagittal plane; C-diameter line: , The maximum straight line distance between the right outer eye point; D line: the maximum linear distance between the left and right zygomatic points on the coronal plane; three-dimensional reconstruction of the MRI image data using VGStudio MAX 2.2 software directly using software measurement tools The relevant craniofacial diameters were measured and analyzed by SPSS 16.0. Results The average diameter of A, B, C and D lines were (237.54 ± 8.63) mm, (173.07 ± 8.28) mm, (89.58 ± 4.46) mm and (127.34 ± 8.16) mm, respectively, <0.01). There was a significant linear correlation between the diameters of A, C, D and the height, the diameters of A, D and weight, the diameter of C, and the age. Conclusion There are significant gender differences in craniofacial diameters of Chinese Han adults. There are significant differences in the diameters of A, C, D and height, A, D and weight, C diameter and age The linear relationship between.
