폐쇄성 수면무호흡증 진단을 위한 두부규격 방사선사진 계측 분석에 의한 한국 성인 정상교합자의 정상치에 관한 연구

Abstract

Purpose : The lateral cephalometric Korean norms of the skeletal and pharyngeal dimension were analyzed for the diagnosis of obstructive sleep apnea syndrome(OSAS). Materials and Methods : The lateral cephalometric radiographies were taken in male(n=53) and female(n=50), who had a normal profile, class I occlusion, normal ANB (0∼4 ∘ )(0∼4∘) and normal Wits Appraisal(−4∼0mm) Appraisal(−4∼0mm). The X-rays were traced by two oral and maxillofacial surgeons twice. The significant differences between male-female and examiners were tested. Results : The angle of mandibular line to Nasion-Sella line was 31.12 ∘ /33.79 ∘ 31.12∘/33.79∘ (in male/in female, p=0.0018). The lower Gonion angle was 73.74 ∘ /73.74 ∘ (p=0.9978) 73.74∘/73.74∘(p=0.9978). The length of the soft palate was 36.93mm/34.35mm(p=0.0002). The pharyngeal airway space was 13.42mm/11.55mm at mandibular plane level(PAS(ML))(p=0.0025). The hyoid was placed inferiorly to mandibular plane 0.18mm/7.72mm(p=0.0051). The results from this study are to be used for the diagnosis of OSAS.
