Exploring the facial asymmetries between Croatian males and females stereo photogrammetric shells

Aim: To explore extent of the asymmetry between the facial shapes of the Croatian male and female subjects. Material and Method: The sample consisted of 73 white Croatian (52% females average age 23 years) ; subjects were scanned with their head in natural position with neutral face expression with a non- invasive stereo photography face scanner. The total of 21 landmarks was positioned and used for creation of the face shells of each subject. Facial shells were divided into 8 regions (forehead, right eye, left eye, right cheek, left cheek, nose, upper lip and philtrum, lower lip and chin) ; surface based comparison explored differences between those regions. All comparisons were performed for male and female groups. The ANOVA was used for between groups comparison at p<0.05. Results: There were no significant differences between the regions on the males’ and females’ facial shells. The match within the tolerance of 0.75mm for the mirror shell was 72.97% ± 10.15% for the females and 71.19% ± 9.52% for the males. Highest percentage for the match within the tolerance of 0.75mm was in the region of upper lip for both females (87.13% ± 10.27%) and males (80.51% ± 15.59%). Conclusion: There are no significant differences in the amount and direction of facial asymmetries between Croatian males and females.
