OBSTRUCTIVE SLEEP APNEA SYNDROME (OSAS). WHAT’S NEW?

This Research Topic entitled “Obstructive sleep apnea syndrome (OSAS). What’s new?”, involving authors from different specializations and numerous countries, confirms that OSAS is a hot topic. OSA syndrome is an airway obstruction (i.e. complete or partial) with numerous etiologies (1–4). Different papers have demonstrated that the prevalence of OSAS is 2–4% in men and 1–2% in women of average age. The reference tools for OSAS diagnosis are clinical polysomnography or nocturnal portable multi-channel monitoring. Frequently, continuous positive airway pressure (CPAP) therapy is the first treatment for a patient (5, 6). Long-term CPAP treatment may present limited compliance, and there is no unanimous opinion on other alternative treatments for OSAS in literature on the subject. This special issue discusses several of these “unmet needs”.
