Chronic cough in infants and children: An update

Cough is a symptom frequently encountered by the otolaryngologist—head and neck surgeon. Although most coughs are self limited, chronic cough often proves to be a frustrating problem. Seventy‐two infants and children under age 16 with a normal chest radiogram have now been evaluated for chronic cough persisting for longer than 4 weeks. Cough‐variant asthma was the most common cause of cough, followed by sinusitis, gastroesophageal reflux, aberrant innominate artery, psychogenic cough, and sub‐glottic stenosis.
