We describe a case of an unsuspected button battery foreign body in the ear canal causing symptoms that mimic malignant otitis externa in a previously healthy 13 year old. Button batteries in the ear canal may cause extensive liquefactive necrosis of the surrounding tissue by leaking an alkaline electrolyte solution. Suspicion of a foreign body should be maintained in any child presenting with a complicated otitis externa. Prompt evaluation and removal of button batteries are necessary to prevent tissue destruction.
我们描述了一例发生在一名13岁此前健康儿童身上的病例，其外耳道内有一枚未被察觉的纽扣电池异物，所引发的症状酷似恶性外耳道炎。耳道内的纽扣电池可能会因碱性电解液泄漏而导致周围组织广泛液化性坏死。对于任何出现复杂性外耳道炎的儿童，都应怀疑有异物存在。必须及时评估并取出纽扣电池，以防止组织破坏。
