Understanding Otitis Externa: A Guide to Swimmer’s Ear

Introduction

Summertime often brings to mind fun days at the pool listening to the wildlife and enjoying the surroundings, but it can also bring about an unpleasant condition known as otitis externa, commonly referred to as swimmer’s ear. This condition is not only common among swimmers but can affect anyone exposed to moisture and bacteria in the ear canal. At KLear Clinic, we believe in empowering our patients with knowledge, so here’s an in-depth look at what otitis externa is, how it can be prevented, and what to do if you suspect you have it.

What is Otitis Externa?

Otitis externa is an infection of the outer ear canal, the tube that connects the outer ear to the eardrum. This infection is usually caused by bacteria, but it can also be due to fungi or viruses. The condition is called swimmer’s ear because it frequently develops in people who spend a lot of time in water, which can trap moisture in the ear canal, creating an ideal environment for germs to thrive.

Causes and Risk Factors

While swimming is the most well-known cause, otitis externa can occur from other activities that expose the ear to moisture or injury. Common causes include:

• Excessive Moisture: Swimming, bathing, or humid weather can increase moisture in the ear canal, promoting bacterial growth.

• Injury to the Ear Canal: Using cotton swabs, fingernails, or other objects to clean the ear can damage the delicate skin of the ear canal, making it more susceptible to infection.

• Skin Conditions: Eczema, psoriasis, or other chronic skin conditions can predispose the ear canal to infection.

Symptoms of Otitis Externa

The symptoms of otitis externa can range from mild to severe, and they usually appear within a few days of exposure to the causative factors. Common symptoms include:

• Itching: Often the first sign, the ear may feel persistently itchy.

• Redness and Swelling: The outer ear and ear canal may appear red and swollen.

• Pain: The ear may become painful, especially when pulling on the earlobe or when chewing.

• Discharge: A clear, watery discharge may come from the ear. In more severe cases, the discharge may become yellowish or pus-like.

• Hearing Loss: Swelling or discharge can block the ear canal, leading to temporary hearing loss.

Prevention Tips

Preventing otitis externa involves minimising the ear’s exposure to moisture and avoiding injury to the ear canal. Here are some tips:

• Keep Ears Dry: After swimming or bathing, dry your ears thoroughly. Tilt your head to each side to allow water to escape, and use a towel to dry the outer ear.

• Avoid Inserting Objects: Don’t use cotton swabs, fingers, or any objects to clean your ears. If earwax is a concern, consider using ear drops designed to soften and remove wax.

• Use Earplugs: Swimmers can use earplugs or a swim cap to keep water out of the ears.

• Be Cautious with Earphones and Hearing Aids: Make sure these devices are clean and dry before use.

Treatment Options

If you suspect you have otitis externa, it’s important to see a healthcare professional for proper diagnosis and treatment. Treatment typically involves:

• Ear Drops: Antibiotic or antifungal ear drops are commonly prescribed to treat the infection. In some cases, a corticosteroid may be added to reduce inflammation.

• Pain Management: Over-the-counter pain relievers, like ibuprofen or paracetamol, can help manage discomfort.

• Keep the Ear Dry: While undergoing treatment, it’s crucial to keep the affected ear dry. Avoid swimming, and take care when bathing or washing your hair.

When to Seek Medical Attention

Most cases of otitis externa can be managed with proper treatment and care. However, if you experience severe pain, fever, or the infection spreads beyond the ear, seek immediate medical attention. Complications are rare but can include long-term damage to the ear canal and nearby tissues.
