[The analysis of frontal facial soft tissue of normal native adult of han race of Guangdong province by using the computer assisted photogrammetric-system].

UNLABELLED: The authors analysed the feature of frontal facial soft tissue of 150 native adults of Guangdong province by using the computer assisted photogrammetric-system made by the authors, which contained several new mode parameters planed by the authors. THE
RESULTS: 1. The mean measurements of six parameters (Sn-Mes, Gs-Mes, Exr-Exl, Enr-Enl. [symbol: see text]Zyr-Rc-Mes, [symbol: see text]Zyl-Lc-Mes.) of the male subjects were larger than those of the female subjects, and the mean measurements of two parameters (Zyr-Zyl/Gs-Mes, Rc-Lc/Gs-Mes) of the male subjects were smaller than the ones of the female subjects. 2. The four measurements (Tr-Mes, Gs-Sn, Zyr-Zyl, Chr-Chl) in both male and female subjects of Guangdong province were smaller than the ones of Sichuan and Shandong provinces, and one measurement (Tr-Gs) of Guangdong male subjects was also smaller than the one of Sichuan or Shandong province, and one measurement of Guangdong female subjects smaller than the one of Shandong province. The conclusions: 1. The normal native adults of han race of Guangdong province show sex-difference and region-difference in the feature of frontal facial soft tissue. 2. The new-mode parameters (such as: [symbol: see text]Zyr-RC-Mes, [symbol: see text]Zyl-Lc-Mes, Zyr-Zyl/Gs-Mes, Rc-Lc/Gs-Mes) are helpful in studying the feature of frontal facial soft tissue.
