This second edition provides an up-to-date and comprehensive overview of Obstructive Sleep Apnea (OSA) that is accessible to patients. OSA can have a significant and progressive impact on the lives of those who suffer from daytime sleepiness, but it is often not considered. Moreover, individuals with the condition are often unaware of it as it affects them during sleep. The book provides knowledge on appropriate pathways for investigation and treatment. The organization and clarity of the writing make it easy for readers who want quick information on diagnosis, symptoms, treatment, and more. The thorough history section covering anatomical evolution, the history of medicine, and modern-day medical and surgical advances will satisfy curious readers. Ample original hand-drawn diagrams, as well as interactive media, increase the readability and approachability of the work, making pathophysiology and surgical procedures clear and accessible. The book also includes links and descriptions of up-to-date procedures, diagnostic techniques, and devices, guiding readers confidently towards other resources beyond the book for further information. This guide is thoughtfully crafted for the general public, including medical laypersons, patients affected by obstructive sleep apnea (OSA), and their families. In addition to its primary audience, the book will also appeal to general practitioners, ENT students, and OSA specialists,
