Abstract
PURPOSE OF REVIEW: Cough lasting more than 8 weeks is a common presenting complaint to the otolaryngologist. Historically, chronic cough has been attributed to post-nasal drip, laryngopharyngeal reflux and cough-variant asthma. This study reviews chronic cough from the viewpoint of an otolaryngologist. RECENT FINDINGS: More recent studies suggest the influence of laryngeal neuropathy and its interplay with laryngopharyngeal reflux. There is limited evidence for post-nasal drip or cough-variant asthma causing chronic cough. SUMMARY: In this study, we review the evidence for cause of chronic cough, as well as up to date techniques for the otolaryngologist, including transnasal esophagoscopy, to assess the patient in clinic allowing accurate diagnosis. Treatment options for the otolaryngologist are discussed and the role of multidisciplinary input emphasized.
