Abstract
Serial lateral cephalometric radiographs of 40 Korean children(25 males, 15 females) ranging in age from 6 to 13 years were studied by means of computer morphometrics and statistical analysis. As a result of this study, the following conclusions can be made: 1. In both sexes, the mean growth patterns of the face were very stable and the growth directions of the face were more prominent both forward and down-ward away from the cranial base(S-N). 2. In the mandible, the rotation and the 'wave-like' manner of migration were observed. 3. The size of the lateral faces in males was larger than females at 6 and 13 years of age, and the forms of the lateral faces in males were slightly more squares than females at 13 years of age. 4. The sex differences and practical means in the growth increments and growth rates during 7 years of the growth period were as follows: (1) In the total face, there was a significant sex difference in the growth increments(males
