    Abstract:
    OBJECTIVE: To improve the therapy effect of uvulopalatopharyngoplasty (UPPP) for the obstructive sleep apnea syndrome (OSAS) with the use of sleep pharyngolaryngoscopy and the Müller maneuver to localize pharyngeal airway collapse. METHOD: Twenty-eight patients with OSAS were divided into two groups respectively based on findings of Müller maneuver and sleep pharyngolaryngoscopy: Type I had only oropharyngeal(soft palate and palatine tonsil) collapse and type II had oropharyngeal collapse with hypopharyngeal collapse. All outcome of PSG after UPPP was analyzed. RESULT: 1. In Type I, the change of the average apnea hypopnea index (AHI) and the lowest SaO2 before and after UPPP was 52.7 to 19.7 (P < 0.01), 63.1% to 80.0% (P < 0.01) using Müller maneuver, and 48.6 to 18.7(P < 0.01), 65% to 80%(P < 0.01) using sleep pharyngolaryngoscopy respectively; In type II, the change was respectively 54.7 to 38.6(P > 0.05), 60.7% to 67.0%(P > 0.05) using Müller maneuver, and 59 to 34(P < 0.01), 59% to 71%(P < 0.05) using sleep pharyngolaryngoscopy. 2. Surgical response rate in type I was compared with type II: 68.4% VS 22.2% (P < 0.01) using Müller maneuver and 73.3% VS 30.8% (P < 0.05) using sleep pharyngolaryngoscopy, respectively. CONCLUSION: Endoscopic pharyngeal assessment of OSAS patients has clinical value for the improvement of UPPP outcome.
