Abstract
Objective To explore the correlation between the imaging parameters of skull and the external features of eyes.Methods Positive images of the head face and the frontal and lateral X-ray films were obtained from 101 cases of adult males of the Han nationality aged from 20 to 40 years old in Northeast China.The face width (x1),upper face width (x2),biorbital width (x3),all facial height (x4),upper facial height (x5),maximum breadth of skull (x6),minimum breadth of frontal bone (x7),orbital width Ⅱ (x8),anterior interorbital breadth (xg),maximum height of skull (x10),minimum width of nasal bone (x11) and orbital height (x12) were measured and the data were statistically analysed.Results Through the linear regression analysis,the regression equations of the presumed inboard canthi (y1) and outboard canthi distances (y2) were established,respectively,which were y1=0.025 x2+0.291 x3-0.011 x7+0.041 x10-0.525(R=0.613,SEE=0.222 cm) and y2=1.703-0.08x2+0.573 x3-0.142x4+0.421 x5+0.096x7-0.256x8+0.149x9+0.071x10(R=0.745,SEE=0.341 cm).The back-substitution check showed that the accuracy rate of two equations at ±1SEE were 75.2％ and 80.2％,respectively.Conclusion The established regression equations of external features of eyes have high estimation accuracy,which can be used to the practical work of facial reconstruction.关键词
