Malignant or necrotising otitis externa is a rare but potentially fatal disease. The classic presentation is one of severe, unremitting, throbbing otalgia, which may progress to osteomyelitis, especially in the elderly diabetic or immunocompromised patient. The case described is of a 72-year-old immunocompetent, non-diabetic man who presented with facial weakness, dysphagia and weight loss. The admitting diagnosis or impression was that of a cerebrovascular event. The eventual diagnosis was that of skull based osteomyelitis secondary to malignant otitis externa complicating mastoid surgery.
恶性或坏死性外耳道炎是一种罕见但可能致命的疾病。典型表现为严重、持续、搏动性耳痛，可进展为骨髓炎，尤其在老年糖尿病患者或免疫功能低下患者中。本文描述的病例是一名72岁免疫功能正常、非糖尿病男性，表现为面部无力、吞咽困难和体重减轻。入院诊断或初步印象为脑血管事件。最终诊断为继发于恶性外耳道炎并使乳突手术复杂化的颅骨骨髓炎。
