Abstract:
Objective To define the characteristic values of the pharyngeal cavity by comparing the values of measures and ratios between the patients with obstructive sheep apnea-hypopnea syndrome(OSAS) and controls.Methods Sixty-eight OSAS patients who were diagnosed using polysomnography,and 56 healthy people were scanned by MSCT(multiple slices computed tomography)in the awake state.Then, the values were measured on the reformated images and were compared between two groups.Results Of the 63 values,49 values were different between the two groups,and among those,4 values were entered into the Discriminant Functions.These were the left-right diameter(LR)[OSAS:LR=(9.4?3.7)mm,controls: LR=(20.1?5.0)mm,t=-13.820,P=0.000)and the cross-sectional area(XSA)[OSAS:XSA= (54?27)mm~2,controls:XSA=(164?77)mm~2,t=-10.944,P=0.000]of RP,the heights of tongue [OSAS:(75.4?8.3)mm,controls:(58.4?9.8)mm,t=10.476,P=0.000],the lengths of uvula/the lengths of airway(OSAS:0.139?0.039,controls:0.154?0.048,t=-1.983,P=0.050).Conclusions Many measures and ratios were different between the two groups,but there were overlaps between them. Measures using the Discriminant Functions can help the diagnosis of OSAS.
