Biennial serial cephalometric radiographs of 47 children (26 boys, 21 girls) were used to analyze the craniofacial growth changes in Korean children from 8 years to 16 years of age. A craniofacial model was designed for this study. It consisted of 72 anatomical points and 98 derived points. The craniofacial changes of these samples during these ages might be summarized as follows: 1. Mandibular growth to cranial base was more forward than maxillary growth. 2. Mandibular growth during this period was found to be a forward-upward (bite closing) rota?tion of the mandible. 3. Growth changes in total mandibular length (Ar-Gn) showed a pubertal growth spurt at 12-14 years of age in boys and 10-12 years of age in girls. Synchrony of the growth spurts on total mandibular length (Ar-Gn) and standing body height was found. 4. The pubertal spurts occured in the growth of total cranial base (Ba-Na) at 10-12 years of age in boys and 8-10 years of age in girls. The time of the spurts of the cranial base growth was 2 years ahead of that of the total mandibular growth. 5. Synchrony of growth spurts in anterior facial height (Na-Me), posterior facial height (S-Go) and body height was found. 6. The whole craniofacial changes during this period were plotted by using a X-Y plotter and personal computer. A simple profi1ogram for an diagnostic tool was obtained.
