초록
연구는 비폐쇄를 보이는 III급 부정교합아동에서, 기도 공간의 형태와 안모 골격 형태 사이의 상관관계를 평가하였다. III급 부정교합을 보이며, 비폐쇄 소견을 보여 이비인후과로 의뢰된 환아 100명의 초진 측모 두부 규격 방사선 사진에서 상 인두기도 공간(upper PAS), 하 인두기도 공간(lower PAS), 편도의 크기, 구개-혀 공간을 측정하여 기도 공간 형태를 분석하였으며, 통상적인 계측점을 사용하여 안면 골격 분석을 시행하여 기도 공간 형태 계측항목과 안면 골격분성 항목간의 상관관계를 연구하여 다음과 같은 결과를 얻었다. Upper PAS는 ramal height, SNA, SNB, PFH, FHR, facial plane angle 항목과 양의 상관관계를 보였으며, saddle angle, articular angle, gonial angle의 sum, SN-GoGn, Y-axis to SN, FMA 항목과 음의 상관관계를 보였다. Lower PAS는 gonial angle, FMA와 양의 상관관계를 보였으며, articular angle, facial depth, PFH, FHR와 음의 상관관계를 보였다. 편도의 크기는 PCBL, ramal height, Mn. body length, Mn. body length to ACBL, facial depth, facial length, PFH, AFH와 양의 상관관계를 보였다. 구개-혀 공간은 saddle angle, articular angle, gonial angle의 합, facial length, AFH, FMA, LFH와 양의 상관관계를 보였으며, IMPA, overbite와 음의 상관관계를 보였다.

Abstract
Objective: The aim of this study was assessment of the relationship between airway space and facial morphology in Class III children with nasal obstruction. Methods: For this study, 100 Class III children (50 boys and 50 girls) were chosen. All subjects were refered to ENT, due to nasal obstruction. Airway space measurements and facial morphology measurements were measured on lateral cephalometric radiograph. Pearson correlation analysis was used to assess the relationship between airway space and facial morphology. Results: Ramal height, SNA, SNB, PFH, FHR and facial plane angle were positively related to upper PAS, and sum of saddle angle, articular angle, and gonial angle, SN-GoGn, Y-axis to SN and FMA negatively related to upper PAS. Gonial angle, FMA were positively related to lower PAS, and articular angle, facial depth, PFH and FHR negatively related to lower PAS. PCBL, ramal height, Mn. body length, Mn. body length to ACBL, facial depth, facial length, PFH and AFH were positively related to tonsil size. Sum of saddle angle, articular angle, gonial angle, facial length, AFH, FMA and LFH were positively related to tongue gap, and IMPA and overbite was negatively related to tongue gap. Upper PAS, related to size of adenoid tissue, was mainly related to posterior facial dimension following a vertical growth pattern of face and mandibular rotation. Lower PAS and tonsil size, related to anterior-posterior tongue base position, were significantly related to each other. Lower PAS was related to growth pattern of mandible, and tonsil size was related to size of mandible and horizontal growth pattern of face. Tongue gap was related to anterior facial dimension following a vertical growth pattern of face. Conclusion: Significant relationship exists between airway space and facial morphology.
