Abstract

This study aimed to evaluate the nasopharyngeal and oropharyngeal dimensions of the patients with skeletal class II division 1 or division 2 patterns during the pre-peak, peak, and post-peak growth periods for comparison with a skeletal class I control group (79 for pre-peak, 40 for peak, 40 for post-peak). Total 159 lateral cephalograms (70 for skeletal class I, 51 for skeletal class II, division 1, and 38 for skeletal class II, division 2) were selected. The growth of anteroposterior dimension of the pharyngeal airway were statistically significant among growth periods. The dimension for the nasopharyngeal and oropharyngeal airway space was the smallest in the division 1 skeletal class II group followed by class II division 2 and skeletal class I.

본 연구의 목적은 소아 및 청소년의 성장단계별(성장급증기 이전, 성장급증기, 성장급증기 이후) 골격성 II급 1류 및 2류 환자의 비인후 및 구강인후 부위인 상기도부의 기도 폭경을 평가하기 위함이다. 골격성 I급 청소년을 대조군으로 하였다. 전남대학교 치과병원 소아치과에 내원한 소아 및 청소년환자 159명(골격성 I급 70명, 골격성 II급 1류 51명, II급 2류 38명)을 대상으로 하였다. 측모두부 방사선사진과 수완부 방사선사진을 이용하여 성장단계별로 분류하였다(성장급증기 전, 성장급증기, 성장급증기 후). 상기도부의 해부학적 폭경을 측정하기 위해서 13개의 계측점, 5개의 계측각, 5개의 계측선, 3개의 비율을 측정하였다. 그 결과, 비인후 및 구강인후 부위의 전후방 폭경은 조사된 모든 그룹에서 성장과 함께 증가하였다. 부정교합에 따른 비인후 기도부위와 상부 구강인후 기도 부위 폭경의 통계적 차이를 밝히지는 못하였으나, 하부 구강인후 기도부의 전후방 폭경은 골격적 II급 부정교합군이 1급 부정교합군보다 더 좁게 나타났다.
