Ulkokorvatulehdus

Ulkokorvatulehdus, commonly known as swimmer's ear, is an inflammation or infection of the external auditory canal, the passage from the outside of the ear to the eardrum. It is most frequently caused by bacteria, though fungi can also be responsible. Moisture trapped in the ear canal, often from swimming or prolonged exposure to humidity, creates a favorable environment for microbial growth. Irritation to the ear canal lining, such as from scratching with cotton swabs or earwax removal, can also predispose an individual to this condition.

Symptoms of ulkokorvatulehdus typically include itching and discomfort in the ear, followed by pain that may worsen when the ear is touched or when chewing. A feeling of fullness or blockage in the ear, and sometimes a discharge or fluid draining from the ear, can also occur. Hearing may be temporarily reduced due to swelling and discharge.

Diagnosis is usually made based on the patient's symptoms and a physical examination of the ear canal. Treatment aims to reduce inflammation, pain, and eliminate the infection. This often involves cleaning the ear canal by a healthcare professional to remove debris and discharge. Topical antibiotic or antifungal ear drops are prescribed to combat the infection. Pain relievers may also be recommended. Prevention strategies include keeping ears dry, especially after swimming, and avoiding inserting objects into the ear canal.
