초록
본 연구의 목적은 성별에 따른 뼈대 III급 맞물림 장애자의 숨길의 차이를 조사하고 턱얼굴과 숨길의 관련성을 분석하는 것이다. 연구대상자는 ANB가 1도 이하이고 턱교정 수술을 희망하는 자로 총 40명을 판단 표출되었다. 연구대상자는 가쪽 머리뼈계측방사선촬영을 하였고 총 40장의 방사선 사진이 최종 분석에 이용되었다. 변수들은 평균과 표준편차 및 통계분석을 실시하였다. 성별에 따른 계측 각도와 계측 거리는 남성이 여성보다 이마뼈, 위턱, 아래턱, 턱끝 모두가 앞쪽에 위치하였고, 후두인두의 단단조직과 물렁조직 폭경도 남성이 여성보다 길었다. 단단조직 및 물렁조직의 입인두와 계측 각도 및 계측 거리의 상관관계는 통계적으로 유의하지 않았고, 후두인두의 폭경은 남성, 아래턱뼈앞돌출일수록 증가하였으며, 턱끝, 위턱, 이마뼈가 전방에 위치할수록 증가하였다. 숨길 크기에 영향을 미치는 변수는 경조직과 연조직 후두인두 폭경이다.
Abstract
The purpose of this study was to investigate the difference of airway between skeletal Class III malocclusion according to gender and to analyze the relationship between airway size and oral maxillofacial position. The total of 40 study subjects was sampled by judgment sampling, who were under 1 degree ANB and who wanted orthognathic surgery. They were taken with lateral cephalometric radiograph and the photos were used for final analysis. The variables were calculated using mean and standard deviation, those were analyzed by independent t-test, Pearson’s correlation coefficient and multiple regression analysis. It was located forward than the female that was the measurements of frontal bone, maxilla, mandible, and mentum in the male. The laryngeal pharynx size of the hard and soft tissues was also longer than the female. It was not statistically significant that was the correlation between the variables and the oral pharynx size. However, the width of the laryngeal pharynx increased with male and mandibular protrusion, and it was increased with the position of the anterior of frontal bone, maxilla, and mentum. The variables affecting the airway size are the laryngeal pharynx width of the hard and soft tissue.
