(A) longitudinal study of nasopharynx and adenoid growth of Korean children

치의학과/석사[한글] Adenoid비대로 인한 구호흡이 부정교합을 야기시키는 원인요소로 알려진 이후 비인두와 adenoid가 airway 발달에 의한 역할과 안모 및 교합에 미치는 영향에 대하여 많은 연구보고가 있었다. 본 저자는 adenoid비대로 인한 부정 교합과 안모 변이등을 예방하고, 치료후 예후 예측을 위해 한국인 정상 아동 남자 17명, 여자 19명을 대상으로 7세부터 12세까지 6년에 걸쳐 얻어진 연속 두부 방사선 규격사진을 이용하여 비인두와 Adenoid조직에 대해 유의성이 높다고 인정된 13개 항목을 추측하여 다음과 같은 결론을 얻었다. 1. 남녀 각 연령별 한국인 기준치를 얻었다. 2. 비인두강의 계속적인 성장은 비인두의 depth보다는 height에 의해 큰 영향을 받았다. 3. adenoid의 크기는 여자보다는 남자에서 크게 나타났으며 R, D-AD^^2 부위에서 특히 큰것으로 나타났다. 4. airway percentage는 남자에서는 10세때, 여자에서는 9세때 가장 큰 수치를 보였다. 5. airway percentage, posterior height, D-AD^^1, D-AD^^2, R에서 남녀별 유의차가 큰것으로 나타났다. A LONGITUDINAL STUDY OF NASOPHARYNX AND ADENOID GROWTH OF KOREAN CHILDREN Chung Ju Hwang, D.D.S. Dept. of Dental Science. The Graduate School, Yonsei Univ. (Directed by Prof. Young Kyu Ryu, D.D.S., Ph.D.) Since the fact that mouth breathing resulted from the adenoid hypertropy caused malocclusion was known, many investigators have studied nasophanynx and adenoid in other to clarify the role in relation to the development of airway and the effect on face and occlusion. The author analyzed 13 items in longitudinal cephalometric roentgenograms of 17 boys and 19 girls taken from the ages of 7 to 12 to assess the differential diagnosis mouth breathing, to prevent the malocclusion and facial deformities, and to estimate the treatment prou후osis. The results were as follows : 1. The author made the tables of means and standard deviation for the measured items. 2. The continual growth of nasopharyngeal cavity was more affected by the height than the depth. 3. The size of adenoid was larger in males than in females, especially on R, D- AD^^2. 4. Airway percentages was highest in boys at age 10 and girls at age 9. 5. The items showed higher significant differentiation between males and females were airway percentage, posterior height, D-AD^^1, D-AD^^2, and R.
