Otitis Externa
Otitis Externa
Otitis Externa (pronounced: oh-TIE-tis ex-TER-na), also known as Swimmer's Ear, is an inflammation or infection of the external auditory canal, the outer ear, or the ear lobe. It is a common condition that can occur in people of all ages, but is particularly prevalent among children and young adults.
Etymology
The term "Otitis Externa" is derived from the Greek words "otitis," meaning inflammation of the ear, and "externa," meaning outside. Thus, the term literally translates to "inflammation of the outside ear."
Causes
Otitis Externa is often caused by prolonged exposure to water, which can lead to a breakdown of the skin lining the ear canal, allowing bacteria or fungi to penetrate. Other causes can include Trauma to the ear canal, Allergies, and skin conditions such as Eczema and Psoriasis.
Symptoms
Common symptoms of Otitis Externa include ear pain, which can be severe, a discharge of fluid or pus from the ear, hearing loss, and itching of the ear or ear canal. In severe cases, the ear canal may become blocked, leading to temporary hearing loss.
Treatment
Treatment for Otitis Externa typically involves cleaning the ear canal and using topical medications to treat the infection and reduce inflammation. In severe cases, oral antibiotics may be prescribed. It is also important to avoid further exposure to water and to keep the ear dry to prevent further infection.
