This book has three sections that discuss selected topics on foreign bodies in the ear, nose, and aerodigestive tract in children and adults, which may be organic or inorganic, highlighting recent updates in diagnosis, complications, and management. Organic foreign bodies, unlike inorganic or inert ones, present early due to the more inflammatory response at the site of impaction. For the aerodigestive foreign bodies, the cricopharyngeus is the narrowest part of the airway among the pediatric group with high risks of airway foreign body impaction. For foreign bodies in the aerodigestive tract presenting to the emergency department, foreign body impaction in the airway can be a more dire emergency than in the digestive tract. Nonorganic aerodigestive foreign body ingestion is common in children. Button batteries and magnets pose a serious risk of injury and complications. The chapters are written by experts and individuals with special interest in topics of focus, and they address new clinical and research developments as well as future perspectives of foreign bodies in ENT practice and their respective treatment options. Otorhinolaryngologists, respiratory physicians, research fellows, trainees, and general practitioners will find this book an interesting read and useful in their day-to-day practice.
