Abstract:

Objective To study the change law of head-face morphological characters with the increasing age. Method Thirty-eight physical indices of head and face of 311 Gejia adults (159 males, 152 females) were investigated in Huangping county of Guizhou province. Twelve physical indices of head and face were calculated. Preliminary analysis was carried out on the age change of head-face morphological characteristics. Results With increasing age, the Mongoloid fold rate decreased, eye color became shallow, the height of the narrow part of the upper lip raised, and lip thickness decreased. Correlation analysis showed that morphological facial height, upper lip height, physiognomic ear length, and physiognomic ear breadth were positively correlated with age. In contrast, head breadth, external biocular breadth, lip height, and thickness of the lips were negatively correlated. The minimum frontal breadth, bigonial diameter, interocular breadth, mouth breadth, nasal depth showed no correlation with age variation. With increasing age, physiognomic facial height, morphological facial height, transverse cephalo-facial index, and vertical cephalo-facial index were ascending. Moreover, cephalic index, length-height index of head and lip index were declining. Conclusion With the growth,the head and face measurements, index of craniofacial characteristic and the proportion of observed indices change with regularity.
