A foreign body in the ear canal can cause trauma and infection, especially in young children ages 2-4 who may insert objects in their ears out of curiosity while playing. Common symptoms of a foreign body in the ear include ear pain, discharge, reduced hearing, and a sensation of fullness, but physical findings can vary depending on the type and size of the object and how long it has been lodged in the ear canal. A thorough history and physical exam is needed to identify the presence of a foreign body in the ear.
