Abstract
Background and Objectives:The aims of this study were to evaluate the anatomical features of patients with obstructive sleep apnea syndrome (OSAS) using upper airway computed tomography (CT) in the awake state, and to analyze the cor-relation between anatomical features and severity of polysomnography (PSG) findings. Materials and Methods:Sixty-eight patients presenting with snoring and sleep apnea were included, and upper airway CT in the awake state and PSG were performed in all patients. The average apnea-hypopnea index (AHI) and minimal arterial oxygen saturation (minSaO2) values were calculated. The axial and sagittal images from the level of the nasopharynx to that of the hypopharynx were obtained and measured. The correlations of the anatomical parameters with AHI and minSaO2 were statistically analyzed. Results:The significant parameters correlated with AHI were nasopharynx anterior-posterior (A-P) diameter and transverse diameter, soft palate transverse diameter, uvula length, tongue length, lingual transverse diameter, and hypopharynx A-P diameter & transverse di-ameter. The parameters correlated with minSaO2 were nasopharynx transverse diameter and lingual transverse diameter. Conclusion: Upper airway analysis using CT in awake OSAS patients provides anatomical parameters which correlate with the severity of OSAS. Therefore, upper airway CT in the awake state may be helpful in diagnosing OSAS.
