RESUMEN

Necrotizing (malignant) otitis externa (NOE) is a rare and invasive infection originating in the external acoustic meatus seen most commonly in diabetes and other immunocompromised states. After a protracted course, disease can smolder and extend into the mastoid, skull base, dural sinuses, and intracranially. We present a case of NOE complicated by mastoiditis, dural sinus thrombosis, and Bezold's abscess in an uncontrolled diabetic presenting with a prolonged course of facial nerve palsy. We stress the importance of maintaining a high index of clinical suspicion for NOE in diabetic patients and offering timely, aggressive treatment to mitigate its complications.
