Often referred to as "swimmer’s ear" or otitis externa, this infection affects the outer ear canal and can occur in people of all ages. However, it is particularly prevalent among swimmers, children, and individuals with certain ear conditions. Understanding otitis externa, its causes, and its symptoms is crucial for effective prevention and treatment.
Otitis externa is an infection or inflammation of the external auditory canal, the passage leading from the outer ear to the eardrum. Unlike middle ear infections (otitis media), which occur deeper in the ear, otitis externa specifically affects the outer part of the ear. The disease can be acute, appearing suddenly and resolving within a few weeks, or chronic, persisting for over three months.
The condition typically results from an infection caused by bacteria or fungi that thrive in the moist environment of the ear canal. It can lead to swelling, redness, and irritation of the ear canal, causing discomfort and, in some cases, pain. The inflammation can also result in temporary hearing loss due to ear canal blockage by swelling or discharge.

Otitis externa is often triggered by moisture trapped in the ear canal, which creates an ideal environment for bacteria and fungi to grow. This is why the condition is commonly associated with swimming, leading to its nickname, "swimmer’s ear." However, it’s not just water that can cause this infection. Other factors contributing to the development of otitis externa include:
Inserting objects like cotton swabs, fingers, or hearing aids into the ear can damage the delicate skin of the ear canal, making it more susceptible to infection.
Earplugs or hearing aids can trap moisture inside the ear canal, creating a breeding ground for bacteria.
Individuals with skin conditions such as eczema or psoriasis are more prone to otitis externa because their ear canal skin may already be irritated or broken.
While earwax helps protect the ear, an excess can trap water and debris, increasing the risk of infection.
Understanding these causes is critical to preventing otitis externa, especially for those frequently exposed to water or who have underlying conditions predisposing them to ear infections.
The symptoms of otitis externa can range from mild discomfort to severe pain. Common symptoms include:
Ear pain.
This is the most prevalent symptom, often worsening when the outer ear is touched or when chewing.
Itching.
The ear canal may feel itchy, especially in the early stages of the infection.
Redness and swelling.
The ear canal may appear red and swollen; in some cases, the outer ear may also be affected.
Discharge.
A fluid discharge from the ear, which may be clear, yellow, or pus-like, is another common symptom.
Hearing loss.
If the ear canal becomes blocked by swelling or discharge, temporary hearing loss or a feeling of fullness in the ear can occur.
Symptoms typically develop within a few days of exposure to the causative factors and can last several weeks if not treated properly. The infection can spread beyond the ear canal in severe cases, leading to more serious complications.
Accurately diagnosing otitis externa is essential for effective treatment and preventing complications. Diagnosis usually begins with a thorough medical history and a physical examination of the ear. Here's how healthcare professionals typically diagnose this condition:
The doctor will ask about symptoms, recent water exposure, or any trauma to the ear. They may also inquire about existing skin conditions or allergies that could contribute to ear infections.
The doctor examines the outer ear and ear canal using an otoscope, a tool with a light and magnifying lens. They look for signs such as redness, swelling, and discharge. The presence of these symptoms, combined with the patient's medical history, usually confirms the diagnosis of otitis externa.
In some cases, if hearing loss is reported, a hearing test may be conducted to determine the extent of the impairment.
If the infection is severe or doesn't respond to initial treatment, the doctor may take a swab of the ear discharge. This sample is sent to a lab to identify the specific bacteria or fungi causing the infection, allowing for more targeted treatment.
Accurate diagnosis is critical to choosing the right treatment approach, ensuring that the condition is effectively managed and complications are avoided.
The treatment for otitis externa focuses on clearing the infection, reducing inflammation, and alleviating pain. The specific treatment approach depends on the severity of the disease and the underlying cause. Common treatment options include:
For treating otitis externa, ear sprays like EarCalm are commonly recommended. EarCalm is an over-the-counter (OTC) spray that contains acetic acid, which helps to fight bacterial and fungal infections by creating an acidic environment that discourages microbial growth. You can purchase EarCalm at most pharmacies without a prescription.
Sometimes, your doctor may prescribe ear sprays that contain additional ingredients such as antibiotics, antifungal agents, or corticosteroids. These prescription ear sprays target more specific infections or reduce inflammation more effectively. These sprays are typically available at a pharmacy and require a prescription from a healthcare provider. They are usually used several times a day, often for about a week to ten days, depending on the severity of the infection.
Over-the-counter pain relievers like paracetamol or ibuprofen are commonly recommended to help manage the pain that often accompanies otitis externa. These medications are easily available at most pharmacies, supermarkets, and convenience stores. They work by reducing inflammation and blocking pain signals to the brain. Paracetamol is often recommended for those who may not tolerate nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen.
Your doctor may prescribe stronger pain relief medications for cases where the pain is more severe. These could include higher doses of ibuprofen, paracetamol or other prescription-based medications. It's important to use these medications as directed by your healthcare provider to avoid potential side effects or complications.
In some cases, a healthcare professional may need to clean the ear canal to remove debris, discharge, or excess earwax that could hinder the effectiveness of ear drops. This procedure, known as aural toileting, can also provide immediate relief from symptoms.
It's important to keep the ear dry during treatment to prevent further irritation or infection. This might involve avoiding swimming or using earplugs during showers.
In some individuals, otitis externa can become a recurrent or chronic issue, requiring a more proactive management approach. Here are some strategies to prevent recurrence:
Keeping the ears clean and dry is crucial for preventing infections. This includes gently drying the outer ear after swimming or bathing and avoiding the insertion of objects like cotton swabs into the ear canal.
If conditions such as localised eczema, psoriasis, or allergies contribute to recurrent infections, managing these underlying issues can help reduce the frequency of otitis externa.
Ear drops for prevention - In individuals prone to infections, the doctor may recommend preventive ear drops, particularly after swimming or exposure to water. These drops usually contain acetic acid, which helps maintain a healthy ear canal environment.
Wearing earplugs or a swim cap when swimming, and avoiding water entry into the ears during showers, can help protect against otitis externa.
Otitis externa is common in children, particularly those who swim frequently or have conditions that affect their health. Special considerations for managing otitis externa in children include:
Ear hygiene. Teaching children the importance of ear hygiene is essential. Encourage them to gently dry their ears after swimming and avoid inserting objects into them. Parents should assist with ear care for young children to ensure proper hygiene.
Monitoring symptoms. Parents should be vigilant for signs of otitis externa in children, such as ear pain, itching, or discharge. Early intervention can prevent the condition from worsening.
Managing ear conditions. For children with underlying conditions such as eczema, it’s essential to manage them effectively to reduce the risk of otitis externa. Regular follow-up with a healthcare provider can help address any persistent issues.
While otitis externa is often manageable with home treatment and over-the-counter medications, there are certain situations where further medical advice is necessary:
Persistent or Severe Symptoms - If symptoms persist despite treatment or the infection seems to worsen, it’s important to seek further medical advice. Persistent pain, swelling, or worsening discharge may indicate a more severe disease or complications.
Hearing Loss - If significant hearing loss is associated with otitis externa, a healthcare provider should be consulted. Hearing loss can indicate a more serious problem that may need specialised treatment.
Underlying health conditions - If an Individual develops otitis externa, they should seek medical advice if they have underlying health conditions, such as diabetes or a weakened immune system. These conditions can increase the risk of complications.
Recurrent infections - For those who experience recurrent otitis externa, a healthcare provider should be consulted to identify any underlying causes and develop a long-term management plan.
Any complications - If there are signs of complications, such as fever, severe pain, or swelling that spreads beyond the ear canal, immediate medical attention is required. These symptoms may indicate that the infection has spread or that there are other underlying issues.
