Development of hemiface size asymmetry.
Facial size asymmetries for the upper and lower face were measured from photographs of 40 neonates (3 days old), 40 preschoolers (2-4 years), and 40 young adults (18-24 years), approximately equally divided by sex. The right hemiface was significantly larger than the left in the three age groups, and there were no differences in the distributions of asymmetry as a function of age.
