Ear foreign body is a foreign body in the external ear canal.[2] Symptoms may vary from none to pain and discharge from the ear.[1] Hearing may be decreased.[1] Complications may include bleeding or skin breakdown.[1]

Objects found in the ear may include beads, cotton swabs, paper, sand, insects, and button batteries.[4][3] Foreign bodies usually become stuck at the narrowing between the cartilage of the pinna of the ear and the bones of the skull.[2] Diagnosis is generally by examination of the ear with an otoscope.[1]

Warmed 1 to 2% lidocaine liquid may be placed in the ear to help numb it before attempted removal.[1][2] Procedural sedation may also be used to facilitate the procedure.[1] A number of techniques may be used for the removal itself including suction, irrigation, and forceps.[1][4] Antibiotic ear drops may be used if their are signs of skin breakdown.[2] Complications of attempted removal may include eardrum perforation.[1]

Ear foreign bodies occur relatively commonly.[3] They occur most often in children and are the most common type of foreign body in this age group.[5][3] Descriptions of ear foreign bodies are found in Ancient literature, including the writing of Hippocrates around 400 BC.[6]

Management

Attempts to irrigate out a foreign body should not be attempted for organic mater that could swell if wet, batteries, or if a eardrum perforation is suspected.[4]

Warmed mineral oil may work well to kill an insect in the ear, after which removal may be carried out.[4]
