Excerpt

Otitis externa (OE) is an inflammation, that can be either infectious or non-infectious, of the external auditory canal. In some cases, inflammation can extend to the outer ear, such as the pinna or tragus. OE can be classified as acute (lasts less than 6 weeks) or chronic (lasts more than 3 months). It is also known as swimmer's ear as it often occurs during the summer and in tropical climates and having retained water in the ears increases the risk for it. The most common cause of acute otitis externa is a bacterial infection. It may be associated with allergies, eczema, and psoriasis.
