Abstract
부정교합의 발생요인의 하나로서 비인두강의 협착이 거론되어 왔다 본 연구는 안면골격의 형태결정에 비인두강의 기여정도를 파악하고자 함에 있다 연구자료 및 방법안 한국인 성인 남녀 156 명의 측모두부X선규격사진(X)을 사용하여 NEC PC-9801 VM2 Personal Computer와 Oscon GT-4000 Digitizer에 의한 data 입력을 행한 후 통계처리를 행하였다 통계처리로서는 각계측치에 대하여 남녀별로 평균치, 표준편차치를 산출, Student’s t-test를 행하고, 비인두강 계측항목과 안면골격의 각 계측치간의 상관관계의 검토를 행하였다 결 과 1 남녀의 성차로서, 여자보다 남자가 상악골에 대해 하악골이 돌출되어 있었으며, 안면고가 컸다 2 Ba-S-PNS와 S-PNS-Ba간에 부의 상관이 인정되어, 이 두 계측치간애 상호작용이 있는 것으로 판단 되었다 3 비인두강의 깊이는 하악의 전후위치관계와 유의한 상관관계를 보였다 4 비인두강의 깊이와 안면의 깊이와는 관련성이 없는 것으로 판단 되었다 5 비인두강의 깊이와 안면고간에 유의한 부의 상관이 시사되었다 6 비인두강의 고경과 안면고간에 유의한 상관관계가 인정되었다.
Since cephalometnc analysis was introduced by Broadbent) into the field of orthodontics, research on the diagnosis of malocclusions and their growth and development has been actively performed Especially, the clanficabon of the morphological and spatial relationship between certam cramofamal structures has been done, and with the cephalometnc method, attempts to predict the growth of the human facial skeleton have been made The endeavor of finding the relationship of some structural deformity or functional m-sufficiency to a certain malocclusion is continued By virtue of the endeavor to clarify the etiology of a certain malocclusion, orthodontists cak treat the patients more effectively than ever before The space problem of nasopharyngeal space, which is one of the etiological factors of maloc-clusions, has been actively mvestmated by some research workers 3-23,28 They argued that the narrowed and/or obstructed nasopharyngeal space is one of the etiological factors of malocclusion They proposed that narrowed and/or obstructed nasopharyngeal space induces the change of oral muscle tonicity, and as a second effect, the morphological changes of facial skeleton occur 3-6, 8-10 Some research workers did not agree to a certain pattern of malocclusion induced by nose-pharyngeal space problem, and it was proved that the type of malocclusion induced by naso-pharyngeal problem vanes 9,10,17 To this suggestion of nasopharyngeal space problems as etiological factors of malocclusion, some research workers disagreed because the correlation coefficients between malocclusions and mouth breathing are too low to be considered as an etiological factor 28 By surveying the interrelationship between the dimension of the nasopharyngeal space and the facial structures with the statistical method, and by comparing the results with other reports, it could be possible to decide whether or not it is acceptable that the narrowed or occluded nasopharyngeal space be blamed as one of the etiological factors of a certain malocclusion
