Obstructive sleep apnea is a condition that is marked by halted or interrupted breathing during sleep.

Anatomy of sleep apnea. The goal of this review is to advance the understanding of the muscular and soft tissue palatal anatomy as it relates to palatal surgery for sleep apnea and the phenotypic variations that generate the shape and collapsibility of the retropalatal airway. Nonetheless upper airway muscle tone is a component of the pathogenesis of sleep apnea but it is only important in patients who have underlying abnormal upper airway anatomy. Sleep apnea is often diagnosed with an overnight sleep test called a polysomnogram or sleep study.

This was the mainstay of treatment in severe sleep apnea before the invention of cpap therapy in 1981. Osa is the most common form. In adults the most common cause of obstructive sleep apnea is excess weight and obesity which is associated with soft tissue of the mouth and.

Though the condition is called sleep apnea each individual pause in breath is known as an apnea. Tracheostomy as a last resort option. Enlarged tonsils or adenoids.

Obstructive sleep apnea osa is a common disorder characterized by repetitive narrowing or collapse of the pharyngeal airway during sleep. There are three forms of sleep apnea. Obstructive sleep apnea pathophysiology anatomy hypoglossal nerve pcrit ventilator control pharyngeal risk factors key points the oropharynx is the most common site of airway collapse in obstructive sleep apnea osa and enlarged parapharyngeal fat pad thicker lateral pharyngeal walls and increased tongue volume play key roles.

Sleep apnea has many different possible causes. Obstructive osa central csa and a combination of the two called mixed. Individuals with normal upper airway anatomy do not develop obstructive apneas or hypopneas during sleep even though they have a reduction in muscle tone and a reduction in the caliber of their upper airway 6 7.

The disorder is associated with major comorbidities including excessive daytime sleepiness and increased risk of cardiovascular disease. Here are just some examples of causes for sleep apnea from anatomical point of view. It bypasses the obstruction of the upper airway which is the primary cause of the disorder.

Risk factors for osa include being overweight a family history of the condition allergies a small airway and enlarged tonsils. Because this happens during sleep many people with osa do not realize that they have this condition.
