Many investigators have studied the grosth changes of craniofacial complex to obtain inportant informations and standard values with which attempts at prediction of growth and treatment results have been under exploration. The author analyzed 360 cephalometric roentgenograms of 40 boys and 50 girls taken from the ages of 6 to 9 to assess the growth changes of craniofacial comlpex and to establish Korean norms by Ricketts’ analysis method. 17 Landmarks, 10 planes and 8 angles were plotted and measured by linearly and angularly. The results were as follows : 1. The author made the tables of means, standard deviations from the measured values. 2. The item which showed sigmificant difference between males and females in longitudinal study was facial axis length. 3. Items which show significant changes during 3 years were cranial base length, facial axis length, lower incisor to APO, Upper molar to PTV in males, and cranial base length, facial axis length, upper molar to PTV in frmales. 4. The correlations between cranial base length and facial axis length to body height and weight were higher in males than in females throughout the items.
