Diagnostic significance of CT scan in patients with obstructive sleep apnea syndrome

Objective To study the characteristic alterations of the upper airway structure and function in patients with obstructive sleep apnea syndrome(OSAS),healthy snorers and healthy subjects with CT scan to evaluate CT scan's value in diagnosis and treatment of OSAS.Methods 166 patients with OSAS,68 healthy snorers and 34 healthy subjects were enrolled in the study.The upper airway area was measured and evaluated using CT canner.Results The area of upper airway of patients with OSAS and healthy snorers is narrower than that of heahthy subjects.The patients with OSAS had more stricture sites in upper airway than the other subjects.Conclusion Upper airway CT scan could play an important role in diagnosis and treatment in OSAS especially in the way of surgical choice.
