Dermatitis of the ear canal is characterized by pruritis, scaling, flaking, and erythema of the skin of the external auditory meatus and ear canal. Dermatitis can be caused by exposure to allergens (contact dermatitis) or can be spontaneous (chronic otitis externa, aural eczematoid dermatitis).

Treatment of Chronic Otitis Externa

  • Avoidance of triggers and/or irritants, including water and cotton-tipped applicators

  • Usually topical corticosteroids

Contact dermatitis of the ear requires avoidance or withdrawal of allergic triggers, especially earrings. Trial and error may be needed to identify the offending agent. Topical corticosteroids (eg, 1% hydrocortisone cream or a more potent 0.1% betamethasone cream) can decrease inflammation and itching. Patients should avoid using cotton swabs, water, and other potential irritants in the ear, because these will aggravate the inflammatory process. Recalcitrant cases can be treated with a short course of an oral corticosteroid (eg, prednisone).

Aural eczematoid dermatitis can be treated with dilute aluminum acetate solution (Burow solution), which can be applied as often as required for comfort. Itching and inflammation can be reduced with topical corticosteroids (eg, 0.1% betamethasone cream). If acute external otitis Treatment Treatment ensues, careful debridement of the ear canal and topical antibiotic therapy (eg, ciprofloxacin 0.3%/dexamethasone 0.1% ) may be required. Potential irritants, including water and cotton swabs, should be avoided.
