What are the causes of Obstructive Sleep Apnoea (OSA)?

As the name suggests, an obstruction in the upper airway is the cause of OSA. In adults, it’s the bulky soft tissue of the soft palate, base of tongue and pharyngeal wall that fall inwards due to high negative pressure generated during inspiration. Contrary to the popular opinion nasal block isn’t only to be blamed for snoring.

In children, it is the bulky tonsils and adenoids that are the main contributors to obstructive sleep apnea


A good history is necessary for making a differential diagnosis. A sleep study can identify the severity of disorder. This is followed by an awake endoscopy to rule out any static anatomical obstruction and a sleep endoscopy endoscopy to identify sites of dynamic obstruction. These two may be combined to a single procedure. Treatment options depend on whether central or obstructive, and the level of obstruction. Both surgical and non surgical management options are available.
