The aim of this study has been to investigate the growth of the pharynx and sexual differences in the lateral cephalograms of Korean children. The material includes 173 cepalograms from two groups composed of 51 males aged 12.0 years and 39 females aged 12.2 years in group 2, and 45 males aged 7.4 years and 39 females aged 7.5 year in group 1, respectively. In order to study and measure the pharyngeal area the following skeletal landmarks were selected: S, N, A, Ptm, B, H, H', M, S-N, FH and CV, and the angle CV-FH was measured to provide a factor for correction of error resulting from improper head positioning of subjects, especially in relative positions of A and H, while radiography. For each variable the statistically treated data have been presented in the table Ⅱ, Ⅲ, Ⅳ. The main results are presented as follows: 1. In general, the measurements of male were larger than those of female in antero-posterior dimension of pharyngeal cavity, but all variables did not show significant sexual differences in both groups when evaluated statistically. 2. All of the measurements were larger in male than in female in vertical dimensions of pharyngeal cavity in group 2, and there were statistical significances of sexual differences in the variables except M-H', but all variables did not show significant sexual differences in group 1 when evaluated statistically. 3. The dimensional increase of the pharynx by the growth in the vertical dimensions was shown to be greater than in the antero-posterior dimensions in the both sexes.
