The hazards of button batteries in the nose

Foreign bodies in the nose are commonly encountered in ORL practice. Miniature button battery impaction in the nose has rarely been reported. Seven such cases have been encountered, each suffering complications directly attributable to the button battery. The complications included septal burns in five patients leading to septal perforation in one child, one case of severe nasal bleeding and one case of necrosis of the lateral nasal wall. The site of maximal damage corresponded with the negative pole of the battery in every case. The possible explanation for this and mechanisms of cellular injury are proposed. This paper underlines the potential hazards of button batteries as foreign bodies in the nose and emphasizes the need for rapid removal and long-term follow-up of these patients.
