Abstract | BACKGROUND: METHODS: During the 3-year study period, 49 OSAS patients suffering from symptomatic nasal obstruction/impaired nasal breathing underwent the standard polysomnography before and after surgery. Polysomnography along with measures of nasal resistance and daytime sleepiness (the Epworth sleepiness scale [ESS] scores) were reviewed also. RESULTS: Surgery decreased the nasal resistance (0.55 +/- 0.37 Pa/cm(3) per second versus 0.17 +/- 0.19 Pa/cm(3) per second; p < 0.001) and ESS scores (11.7 +/- 4.1 versus 3.3 +/- 1.3; p < 0.001), without changes in the apnea-hypopnea index (AHI; 44.6 +/- 22.5 versus 42.5 +/- 22.0). Surgery increased nadir oxygen saturation (76.2 +/- 10.9% versus 78.8 +/- 8.1%; p < 0.01), shortened apnea-hypopnea duration (averaged/maximum; 33.5 +/- 7.3/61.1 +/- 46.0 versus 28.8 +/- 7.4/47.3 +/- 36.1 second; p < 0.05/p < 0.01), and improved sleep quality. CONCLUSION:
