Eosinophilic oesophagitis: an otolaryngologist's perspective.

Eosinophilic oesophagitis is a diagnosis that is being made more frequently in the assessment of dysphagia in both adults and children. It is unclear whether this is a result of increased prevalence or improved diagnostic methods. Children present commonly to paediatric institutions with foreign body impaction. Research indicates that food impaction may predispose to eosinophilic oesophagitis. This article presents eosinophilic oesophagitis from an otolaryngologist's point of view. It details the clinical features present in the disease as well as how it is diagnosed and managed. It illustrates early signs of eosinophilic oesophagitis so that primary physicians and emergency physicians know when to refer on to otolaryngologists.
