Abstract
Upper airway ftinction plays role in the maintenance of the upper airway patency and contributes to the genesis of the obstructive sleep apnea (OSA). A narrowed upper airway is very common among USA patients, and is usually in adults. The vibration or collapse of the soft palate is a significant contributor to snoring of OSA. The study aimed to find the impact oforopharyngeal exercise on patients with moderate obstructive sleep apnea. A total of 34 patients with Apnea Hypopnea Index were included. Prior to the onset of oropharyngeal therapy and polysomnography, each patient completed a validated Epworth sleepiness scale and Quebec sleep questionnaire and baseline measurements are recorded. Among the study population there was a significant improvement in the severity of disease, quality of life, day time sleepiness and neck circumference. The results also suggest that oropharyngeal exercise has significant impact on patients with moderate obstructive sleep apnea.
