tomography(MSCT)in diagnostic value of structural localization in the upper airway of patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods This prospective study recruited 30 patients with OSAHS and 20 healthy volunteers. All participants were received MSCT scanning in awake state. 9 patients with severe OSAHS underwent CT scans again under sleep apnea state. All data were measured by Mimics software. The differences of upper airway morphology were compared between healthy volunteers and patients, and also compared the patients with severe OSAHS in awake state and sleep apnea state. Results (1) The main obstructive position in patients was localized in retropalatal region and retroglossal region under awake state. There was significant difference of retropalatal and retroglossal region between patients and healthy volunteers (P<0. 05) ; (2) The obstructive position in awake state of patients with severe OSAHS was roughly same as in sleep apnea state. Whereas, the most narrow area was localized in the region behind the soft palate and there was a significant difference between awake state and sleep apnea state in
