Perspective Chapter: Classification and Complications of Aerodigestive Button Batteries and Magnets

Abstract

Aerodigestive foreign bodies is a term used to group together airway foreign bodies and oesophageal foreign bodies. Anatomically, the cricopharyngeus is the narrowest part of the airway among the paediatric population with high risks of airway foreign body impaction. Button batteries account for less than 2% of the foreign bodies ingested in children. Non-organic aerodigestive foreign body ingestion is common in children. Button batteries and magnets pose a serious risk of injury and complications. Majority are unwitnessed, requiring a high index of suspicion among children presenting with abdominal discomfort. Urgent removal is indicated.
