Acute Contact Otitis Externa: Symptoms, Causes and Diagnosis

Acute contact otitis externa is a common ear infection that affects the outer ear canal. Also known as swimmer's ear, this condition is caused by bacteria or fungi that thrive in moist environments, such as the ear canal. While acute contact otitis externa can occur in anyone, it is more common in swimmers, individuals who use hearing aids, and those who have eczema or psoriasis.

1. Symptoms: The symptoms of acute contact otitis externa include ear pain, itching, redness, and swelling of the ear canal. Other symptoms may include a foul-smelling discharge, difficulty hearing, and a feeling of fullness in the ear. In severe cases, the infection can spread to other parts of the ear, causing fever and swollen lymph nodes.
2. Causes: Acute contact otitis externa is caused by bacteria or fungi that enter the ear canal through small cuts or abrasions. The infection is most commonly caused by the bacteria Staphylococcus aureus, but can also be caused by Pseudomonas aeruginosa or Candida albicans. Certain activities can increase the risk of developing acute contact otitis externa, such as swimming, using hearing aids or earplugs, and cleaning the ears with cotton swabs or other objects.
3. Diagnosis: To diagnose acute contact otitis externa, a healthcare provider will examine the ear canal using an otoscope. They may also take a sample of any discharge from the ear canal to determine the type of bacteria or fungus causing the infection. In some cases, imaging tests such as a CT scan may be ordered to rule out other conditions.

It is important to seek medical attention if you suspect you have acute contact otitis externa. While this condition can be painful and uncomfortable, it can also lead to complications if left untreated. Your healthcare provider can recommend treatment options, such as antibiotic or antifungal ear drops, to help clear up the infection and alleviate symptoms.

Preventing acute contact otitis externa involves keeping the ear canal clean and dry, avoiding activities that introduce bacteria or fungi to the ear, and treating any underlying skin conditions that may increase the risk of infection. By taking these steps, you can reduce your risk of developing this common ear infection and keep your ears healthy.
