Upper airway imaging techniques for obstructive sleep apnea syndrome

Obstructive sleep apnea syndrome (OSAS) is a sleep disorder marked by recurrent stops in breathing during sleep or by not breathing for 10 seconds or longer despite an effort to breathe. It is brought on by a partial or total blockage of the upper airway, which results in apnea or hypopnea. Soft tissue in the back of the throat collapses and blocks the upper airway when muscles relax while you sleep. The Apnea-Hypopnea Index (AHI) is a widely used metric to quantify sleep apnea. The total number of apneas and hypopneas that happen during an hour of sleep is represented by this average. The majority of people with OSA remain undiagnosed, even with the recent advancements in sleep medicine diagnostic technologies and public awareness of the condition. The upper airway imaging methods for obstructive sleep apnea syndrome will be covered in this review.
