The morphology and growth changes of the Craniofacial Complex are inportant in orthodontics and cephalometrics for analysis and evaluation of facial bone growth are widely used. The author analyzed the data using lateral cephalometric roentgenogram of 75 Korean male and 50 Korean females age of 6 to 10 with normal occlusion to provide informations-relative rates of facial bone growth of Korean which is to be contributed in Korean standard. The results were as follows : 1. Means, standard deviation and coefficrent of variation of Korean children were obtained. 2. The item which showed significent difference between male and female was craniofacial height in absoulte dimension. 3. No difference of sex was showed in increment of cramofacial height and depth. 4. Among the craniofacial depth incements, the lower facial depth dimension increased most, midfacial depth dimension increased less, and cranial depth dimension increased the least. 5. The horizontal body of mandible showed rapid growing tendency more than did the ascendmg ramus.
