Recently button batteries are widely used and are readily available as foreign bodies in the ears, noses, and esophagi of children. Button batteries in the nasal cavity are dangerous because of their ability to cause liquefaction necrosis of contacted mucosa. Batteries found in the nasal cavities should be removed immediately to prevent sequelae such as septal perforation or stenosis of the nasal meatus. We treated two cases of foreign bodies (button battery) in the nasal cavities. In this paper, the potential hazards of button batteries and important points in the treatment will be emphasized.
