Obstructive Sleep Apnea Syndrome (OSAS)

OSAS is the most common type of sleep apnea; it is caused by complete or partial obstruction of the upper airway. This condition is characterized by repetitive episodes of shallow or paused breathing during sleep, despite the effort to breathe, and is usually associated with a reduction in blood oxygen saturation. Severity of OSAS measured by the apnea hypopnea index (AHI) is assessed with the apnomonitor and/or polysomnography (PSG). Patients with an AHI greater than 40 are advised to use nasal-continuous positive airway pressure (CPAP). More than 100 patients use nasal-CPAP in our outpatient clinic; most of them sleep well. We recommend uvulopalatopharyngoplasty (UPPP) for patients with tonsillar hypertrophy.
