Abstract Button batteries spontaneously leak alkaline electrolyte solution on exposure to moisture, causing liquefaction necrosis of adjacent tissue. We describe two cases in which a button battery in the external auditory meatus caused skin, bone and tympanic membrane necrosis. Review of the world literature on button batteries acting as foreign bodies reveals lower motor neurone facial nerve palsy, nasal septal perforation and fatal esophago-aortic fistula as among the ENT complications. Batteries lodged in these sites must be removed as a matter of the utmost urgency.
