Otitis externa refers to any condition in which the epidermis, dermis, or hypodermis of the external auditory meatus becomes infected. Infection may also affect the ear drum or auricle. Otitis externa may occur in various forms, such as acute diffuse, circumscribed, chronic otitis, or malignant (where necrosis is a feature). A number of conditions may be responsible, such as perichondrial inflammation, erysipelas, a fungal infection, herpes zoster of the ear, bullous and hemorrhagic forms, otitis media with a perforated tympanic membrane, eczema, cholesteatoma, or a malignant neoplasm involving the external auditory meatus [1, 2].
