[Septal perforation in children due to button battery lodged in the nose: case series].

Nasal foreign bodies are common in children. Button batteries deserve particular interest due to the severity and precocity of the injuries they cause. The button battery represents a growing danger. Its small size and brilliant appearance make them attractive to children, often being introduced in the nose, ear or mouth. It is imperative that the community and physicians are aware of the risks it poses. Early diagnosis and immediate removal is essential. Their delay can lead to necrosis of the nasal mucosa and septal perforation. We report 10 cases of septal perforation due to button battery. We emphasize the dangers of nasal impaction and the need for quick removal to avoid long-term complications.
