Abstract:
Compared with CT scan results of OSAS patients and normal adults to explore the value of CT diagnosis of upper airway stricture in patients with OSAS, 35 patients with OSAS and 35 normal adults were included in the study. 22, 19, 12, 8 cases had obstruction at palate, uvula, lingua and epiglottis region respectively, the awaked CT scan results of 61 obstructive sites were compared with those of normal adults. Obvious difference was found between patients and normal adults in area, left right dimension and coronal dimension. difference was also found in thickness of lateral pharyngeal tissue of palate, uvula and lingua region and retropharyngeal tissue of palate and uvula. The normal extent was determined by unilateral 95% confidence interval in normal adult group. And 43 sites had abnormal CT scan results, the positive ratio was 72 13%. The results sugget that there are obvious differences between the patients with OSAS and normal adults, the CT scan measure can show the upper airway obstructive site of patients with OSAS.
