Purpose:To investigate the obstructed sites using multi slices spiral computed tomography, and estimate the value of CT in the diagnosis and treatment of OSAHS. Materials and Methods:Fifteen serious OSAHS sufferer who were viewed by PSG and ten normal adults who had no chief complaint of sleeping disease were slected. The curves of subjects in a respiratory cycle were recorded by respiratory monitoring system in PSG. The15patients with OSAHS and10controls were scaned by CT in the phases of quiet stable respiration and Miiller action. The sites of narrow in upper airway were studied. Correlation analysis was carried out between the CT and clinical data. Results:The cross section areas of upper airway of serious OSAHS were smaller than those of the controls,especial at the soft palate and tongue levels.The cross sections areas at the soft palate level under the quiet stable respiration and Muller action states had significant statistical difference among OSAHS and controls. Conclusion:CT scan is relatively convenient and helpful for assessing directly obstructive location of upper airway,for determining therapy plan and loction.
