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.
纽扣电池暴露在潮湿环境中会自发泄漏碱性电解液，导致相邻组织液化坏死。我们描述了两例外耳道纽扣电池导致皮肤、骨骼和鼓膜坏死的病例。回顾关于纽扣电池作为异物的世界文献发现，耳鼻喉科并发症包括下运动神经元性面神经麻痹、鼻中隔穿孔和致命的食管主动脉瘘。位于这些部位的电池必须作为最紧急的事项取出。
