Localization diagnosis of upper airway stricture in patients with obstructive sleep apnea syndrome and operative therapy

[Objective] To apply varies operation methods in threapy of patients with obstructive sleep apnea syndrome (OSAS) based on localization diagnosis of upper airway stricture and to get better effect. [Methods] 98 patients with OSAS were included in the study. The localization diagnosis methods as follows: in awake, conventional physical examination, lateral X-ray photograph, fibre end oscopy examination with Muller's maneuver and CT measurements in upper airway, a nd in sleep,fibre endoscopy examination and CT scan in upper airway. And the ope ration plan were made based on localization diagnosis results. [Results] The l ocalization of upper airway stricture were diagnosed in all 98 patients, and the operation methods varied in difference patients based on the difference of stri ciure site in upper airway. All patients recoverd smoothly without any severity complication. All patients were followed up more than 6 months, and the cure, we ll, utility and inefficiency rate were 39.8%?89.8%?95.9% and 4.1% respectively. [Conclusion] In difference patients, applying difference operation methods bas ed on difference stricture site in upper airway, we can get much better cure eff ect.
