Abstract:
Objective:To investigate the correlation of dentofacial structure and the sagittal size of the upper airway in youthful nonsnoring men with malocclusion.Methods:Lateral cephalometry was carried out in 52 nonsnoring males with malocclusion. The average age of the patients was 19.23 years, with a range of 18 to 24 years. Stepwise regression analysis was used to relate those cephalometric parameters to the sagittal airway size at different levels.Results:SNB angle,S-N length and H-C_3 length were the related variables to superior posterior airway space(SPAS). H-C_3 length,SNB angle and L1-MP angle were the related variables to middle airway space(MAS). SNB angle,H-C_3 length,S-N length and L1-MP angle were the related variables to inferior airway space(IAS).Conclusion:The sagittal upper airway size in youthful nonsnoring men with malocclusion is correlated to the dentofacial structure and the hyoid position.
