Anatomical features of oropharyngeal region as predisposing factor to obstructive sleep apnea syndrome
The range of pathological changes of upper airways, such as soft palate and uvula hypertrophy, tonsillar hypertrophy, the webbing of posterior pillars etc. predispose the obstruction in patients with obstructive sleep apnea. As a result of the study we have come to conclusion that the intensity of upper airways` pathological changes varies according to the grade of obstructive sleep apnea.
