Otolaryngological manifestations in patients with obstructive sleep apnea and continuous positive airway pressure users: A systematic review.
Systematic Review
Sleep disorders have emerged as a significant public health issue, adversely affecting quality of life and precipitating severe complications. The association between obstructive sleep apnea syndrome (OSAS) and otolaryngological manifestations appears to be underrecognized. This study posits that manifestations in the ear, nose and throat (ENT) among patients with OSAS and users of continuous positive airway pressure (CPAP) therapy are relatively common. Utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement, this systematic review, registered at PROSPERO (No. CRD42023452473), involved a comprehensive search of the MEDLINE databases. We included studies published in English from 1979 to March 2021 that explored the linkages between OSAS, CPAP and otolaryngological manifestations. A total of 29 articles were reviewed, with findings indicating 12 studies on ear dysfunctions, 11 on nose dysfunctions and 6 on pharynx dysfunctions. Reported symptoms included hearing dysfunction, vestibular function disorders, cerebrospinal fluid leak, Eustachian tube (ET) dysfunction, rhinosinusitis, olfaction and taste disorders, dysphagia, dry mouth, and gastroesophageal reflux. The etiology of these ailments varies, yet an understanding of these symptoms can improve the diagnosis to confirm or rule out OSAS. Early identification of ENT symptoms related to OSAS may facilitate prompt diagnosis and mitigate serious complications.
