It is estimated by the seminal Wisconsin Sleep Cohort that OSA affects 3% of middle-aged women and 9% of middle-aged men, with incidence increasing in parallel with society’s worsening obesity rates. OSA is among the most common problems seen by Otolaryngologists and a recent NEJM (New England Journal of Medicine) editorial has described OSA as a “perioperative epidemic.”
