Abstract
本 硏究의 目的은 咽頭陸의 成長樣相과 男女間의 性差을 觀察하는데 있다.
硏究資料로서는 7歲群 男子38名, 女子 39名과 12歲郡 男子 51名, 女子 45名이었으며 이들
의 X線頭部側貌規格擺影像에서 前·後길이 및 垂直길이를 計測하여 分析評價하였다. 本 硏
究의 結果는 다음과 같다.
1. 咽頭腔의 前後間의 길이보다는 垂直길이가 男女共히 현저히 컸다.
2. 咽頭腔의 前後 길이는 7歲群과 12歲群 共히 男女間의 性差를 認定할 수 없었다.
3. 咽頭腔의 垂直길이는 7歲群에서는 男女間의 性差가 없었으나 12歲群에서는 M-H' 項目
을 除外한 全 項目에서 男女間의 性差가 현저하였다.
4. 咽頭腔의 增齡에 따른 成長幅은 前·後길이에서는 男女共히 僅少하였으나 垂直길이에
서는 成長幅이 현저하게 컸다.
#초록#
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.
