[Chronic cough related to otorhinolaryngologic disease]

Otorhinolaryngologic etiologies of chronic coughing may be a disturbance of the pharyngo-eosphageal tract or a laryngeal failure such as a palsy or cleft. In children, chronic coughing associated with chronic rhinosinusitis looks much more like a tracheobronchial manifestation of a global respiratory disease than a consequence of upper respiratory tract inflammation.
