영문 초록

This study was conducted to examine the growth change in external nose according to age which plays an important role in determining the facial profile, by analysing the biennial serial lateral cephalograms of 20 males and 20 females of mean 8.5 years old to 16.5 years old who have a normal occlusion. The results of this study were summarized as follows. • Both mean and standard deviation were obtained according to each item, sex and age for the male and female. • Nose heights of the male and female increased with increase in their age. The upper to lower nose height ratio somewhat decreased for both male and female with increase of age. The mean ratio was 3.69 : 1 for the male, respectively, and 3.83 : 1 for the female during this study. • The nose depth indicated the most significant increase of all items according to the increase of age, while the sagittal depth indicated higher value for the female than that of the male in the most age groups. • The nose inclination did not show a remarkable change during this study. • The proportions of growth completed at the earliest age showed the highest percentage for sagittal depth(male : 87.14% & female: 91.29%). Also, the male indicated the lowest percentage in lower nose height (73.04%), while the female did the lowest in nose depth(79.09%). • There was shown the variable of the greatest correlation between the upper nose inclination and nose depth. • From this study, the whole external nasal growth was occurred downward and forward which was more frequent for forward growth than vertical growth.
