Abstract:
In this retrospective cohort study, we tried to evaluate the compliance of continuous positive airway treatment (CPAP) in the patients with or without previous surgical treatment to OSAS. Retrospective study with prospectively collected data was performed. Eighty-six consecutive OSAS patients who decided to try CPAP were enrolled, and data regarding polysomnography, history of previous surgical treatment and CPAP usage were collected. Among them, nine patients who had history of uvulopalatopharyngoplasty for OSAS were included in the surgery group and another 77 non-surgical patients were assigned to the untreated group. There was no statistical difference for demographics or polysomnographic parameters. They showed similar CPAP acceptance and air leak after the first trial. However, the surgery group (6.39 ± 1.49 h/day) used CPAP significantly longer than the untreated group (4.73 ± 1.64 h/day; p = 0.007) and less troubled with 'waking up during night'. The present study showed that the prior surgery for OSAS doesn't preclude the subsequent CPAP therapy.
