Infection of the outer ear
Infection of the Outer Ear
Infection of the outer ear, also known as otitis externa, is an infection of the ear canal that commonly causes pain, swelling, and/or itching in the ear. Otitis externa can also result in some fluid drainage from the ear, hearing loss, and general discomfort. This type of infection is caused by fungi or bacteria and is more common in people with weakened immune systems and those who are exposed to a humid environment or water.
Causes of Otitis Externa
Otitis externa can occur when moisture or water builds up in the ear canal, usually from swimming or showering. This can create a favorable environment for bacteria or fungi to grow. In some people, this can be the result of having a genetic predisposition, such as a narrowed ear canal. Additionally, certain skin conditions and allergies can weaken the ear canal, resulting in a greater risk of infection.
Symptoms of Otitis Externa
The most common symptom of otitis externa is pain in the ear. This pain may be constant or intermittent, and is often made worse by moving the ear, chewing, or touching the ear. Other symptoms of otitis external may include:
- Itching of the ear
- Redness or swelling of the ear
- Fluid drainage from the ear
- Decrease or loss of hearing
Diagnosing and Treating Otitis Externa
A doctor can usually diagnose otitis externa without the need for any tests. The most common treatment option for this type of infection is antibiotics or antifungal medications. In severe cases, a doctor may also recommend steroid medications to reduce inflammation. To prevent the infection from recurring, a doctor may also provide recommendations to avoid swimming or showering with water in the ear.
