Up to 10% of all persons may experience an episode of OE during their lifetime.1,2 OE can be painful and difficult to manage because of the confines of the ear canal. Early diagnosis and a stepwise treatment approach, including debridement and ototopical therapy, and on occasion systemic antimicrobials, are critical to expedient management.
