Abstract

The purpose of this study is to investigate factors influencing the upper airway dimensions in skeletal Class II children and adolescents. In total, 67 patients were selected. Airway volume and minimal cross-sectional area were three-dimensionally assessed. Craniofacial morphology and skeletal maturity were assessed on generated two-dimensional cephalograms. The measurements were analyzed using Mann-Whitney test, one-way ANOVA, Pearson's correlation, and multiple regression analysis. Upper airway dimensions were significantly smaller in pre-peak stage group, and positively associated with age. Anterior facial height and age were the most relevant factors for airway volume. Mandibular width and age were the most relevant factors for minimal cross-sectional area. Upper airway dimensions were significantly associated with age, skeletal maturity and craniofacial morphology in all three planes.

이 연구의 목적은 골격성 2급 부정교합 소아·청소년의 상기도 공간을 분석하고, 이에 영향을 미치는 요인을 알아보고자 함이다. 총 67명의 골격성 2급 소아·청소년의 CBCT영상으로 연구를 진행하였다. 상기도 부피와 최소 단면적은 3차원 CBCT 영상을 통해 평가하였으며, 악안면 형태와 골 성숙도는 2차원 두부방사선사진을 통해 평가하였다. 상기도 부피 및 최소 단면적과 다양한 변수들간의 연관성이 분석되었다. 상기도 공간은 최대 성장기 이전의 환자에서 가장 작았으며, 연령과 양의 상관관계를 보였다. 상기도 부피는 전안면 고경 및 연령과, 최소 단면적은 하악 폭경 및 연령과 가장 높은 상관관계를 나타냈다. 골격성 2급 소아·청소년의 상기도 공간은 연령, 골 성숙도, 세 평면에서의 악안면 형태와 유의한 연관성을 가졌다.
