OSA is distinguished from central sleep apnea which is attributable to an underlying neurological cause. The prevalence of OSA estimated between 1.5-4 percent and is more common in older males. In this episode, we will discuss the relevant anatomy, pathophysiology, clinical presentation as well as surgical evaluation, management, and complications.  By the end of this podcast, listeners will  be able to:  Define obstructive sleep apnea (OSA) Discuss anatomy related to OSA Discuss surgical management options for OSA List complications of surgery for OSA
