Video imaging provides dynamic view of airway obstruction in those with sleep breathing disorder
A video imaging technique demonstrates that the soft palate, the tissue at the back of the roof of the mouth, is more elongated and angled in patients with obstructive sleep apnea both when they sleep and when they are awake, according to a recently published report.
“Obstructive sleep apnea is a common form of sleep-breathing disorder characterized by repetitive episodes of partial or complete upper airway obstruction,” the authors wrote in the article. The condition usually causes breaks in sleeping, reduced blood oxygen levels and daytime sleepiness, and may contribute to cognitive (thinking, learning and memory) difficulties, psychosocial impairments, trouble driving, heart disease and death.
