Abstract:
Objective To evaluate the value of 128-slice CT on locating the obstruction site of the upper airway in obstructive sleep apnea hypopnea syndrome (OSAHS)patients by three-dimensional reconstruction technology.Methods There were 52 patients with OSAHS diagnosed by the PSG and 32 cases of healthy volunteers in our hospital.All objects were performed 128-slice CT scan of the upper airway during awake state,and those patients’upper airways were scaned on Muller test.The airway volume of the ret-ropalatal region,retroglottal region and epiglottal region,and the total length of upper airway were measured,and statistical analysis of the each index was obtained.Results During awake state,compared with the control group,the length of upper airway in OSAHS patients increased significantly(P <0.001).Compared with the awake state,OSAHS patients’airway volume of the retropalatal region, retroglottal region and the total airway volume on the Muller test were reduced significantly(P <0.001).OSAHS patients’upper air-way length was correlated negatively to the average MSaO 2 (r=-0.33,P <0.05).Conclusion The three-dimensional reconstruc-tion of upper airway on 128-slice CT can evaluate the position and degree of the obstruction site in OSAHS patients’upper airway better,which has important significance to guide clinical treatment.
