Otomycosis externa is a fungal infection of the external ear canal. Fungi thrive in warm and humid environments, making the ear canal susceptible to infection when exposed to water, accumulated secretions, or frequent use of antibiotic drops. Common causative fungi include Penicillium, Aspergillus, and Candida albicans.

The ear feels itchy, sometimes extremely so, especially at night. Examination reveals the external auditory canal and eardrum covered with yellow or white powdery or velvety moss-like membranes. Occasionally, secretions or crusts form tubular shapes, and upon removal, the affected area appears slightly congested and moist. If a bacterial infection is present, there may be ear pain and pus discharge. In mild cases, there may be no symptoms, and the condition is only discovered during examination.

Remove all scabs and secretions from the external ear canal, and apply 1-2% salicylic acid alcohol, 1-2% thymol alcohol, or 1:1000 benzalkonium bromide alcohol to the ear. Alternatively, nystatin can be sprayed into the external ear canal or clotrimazole cream can be applied. Keep the external ear canal as dry as possible.
