Fungal Infection in the Ear: Symptoms, Causes and Treatment Methods

A fungal ear infection, also known as otomycosis, is an infection of the ear canal caused by fungi. It can sometimes be misdiagnosed as an outer ear infection (otitis externa) due to similar symptoms such as itching, discharge, and discomfort. In general, fungal ear infections are less common than bacterial ear infections.

This article will delve into the key information about fungal ear infections, including their symptoms, causes, treatments, and frequently asked questions.

Symptoms of a Fungal Infection in the Ear

Common symptoms of a fungal ear infection include:

• Itching or irritation in the ear canal
• Thick yellow discharge/pus
• Redness or swelling inside the ear
• A feeling of fullness in the ear
• Hearing loss or muffled hearing
• Flaky skin around the ear canal

Causes and Risk Factors of a Fungal Infection in the Ear

Fungal ear infections typically occur due to an overgrowth of fungi such as Aspergillus and Candida in the ear canal. Some groups of people are more likely to develop fungal ear infections than others because of certain factors including:

• Regular water exposure: Regular exposure to water can lead to a condition known as ‘swimmer’s ear’, where excess moisture in the ear canal reduces the protective function of earwax. This, in turn, increases the risk of a fungal ear infection.

• Diabetes: Diabetes can impair immune function and blood circulation, making it harder for the body to fight infections. As such, individuals with diabetes are at greater risk of developing fungal ear infections.

• Compromised immune system: Individuals with conditions such as HIV/AIDS, cancer or those undergoing immunotherapy treatments such as chemotherapy may find it difficult to combat infections.

• Eczema or dermatitis: Skin conditions that cause inflammation or irritation in the ear canal can compromise the skin’s barrier, increasing the individual’s susceptibility to fungal ear infections.

• Humid climates: Warm and humid environments tend to allow fungi to thrive. Thus, those living in humid or tropical climates may be more at risk of developing fungal ear infections.

• Frequent ear cleaning: Earwax serves as a natural protective barrier for the ear canal. It has antibacterial and antifungal properties that help inhibit the growth of harmful bacteria and fungi. Individuals who use cotton swabs or other tools to clean their ears may end up removing too much earwax, increasing their vulnerability to ear infections.

Seeing a Doctor for a Fungal Infection in the Ear

People generally seek medical help for ear infections when they experience discomfort or notice unusual discharge from their ear. Symptoms that often prompt a visit to the doctor include:

• Persistent ear pain
• Fullness in the ear
• Foul-smelling discharge
• Hearing loss
• Itching or irritation
• Redness or swelling around the ear
• Fever

Diagnosing a fungal ear infection typically involves a physical examination using an otoscope to look inside the ear canal for signs of infection, such as redness or swelling. Sometimes, fungal spores may be seen in the ear canal. The doctor will also consider your symptoms and medical history to understand the context of your condition better.

Furthermore, a lab test may be conducted if needed, where a sample of ear discharge or skin debris is examined under a microscope or cultured to identify the type of infection and the specific fungus involved. 

Treatment for a Fungal Infection in the Ear

Treating a fungal ear infection involves a variety of methods to eliminate the infection and relieve symptoms. Here’s a closer look at how these treatments work to address a fungal ear infection effectively.

Tip!

While awaiting treatment for a fungal ear infection, avoid scratching the ear canal or using Q-tips as this can worsen irritation. Keep the ear dry by avoiding moisture, and refrain from using hearing aids or earphones to prevent further irritation.

Ear cleaning

During ear cleaning, the doctor will carefully remove debris, discharge or infected material from the ear canal. This process usually involves the use of specialised instruments such as ear curettes or suction devices. By removing the discharge, the antifungal medications can work more effectively.

Antifungal ear drops

The active ingredients in antifungal ear drops destroy fungal cells. This localised treatment helps to eliminate the infection and provide relief from symptoms. Furthermore, by addressing the infection directly, these ear drops help prevent the spread of the fungus and support faster recovery.

Medication

For more severe cases of fungal ear infections, oral antifungal medications may be prescribed. These systemic treatments are used when topical treatments like ear drops are insufficient or if the infection has spread beyond the ear canal.

Preventing a Fungal Infection in the Ear

To prevent fungal ear infections, try adopting the following habits:

• Avoid digging your ears: Allow your ear’s natural cleaning mechanism to clear out earwax rather than cleaning your ears on your own. Retaining a small amount of earwax helps prevent fungal ear infections.
• Avoid inserting objects into your ear canal: Refrain from inserting cotton swabs or any other objects into your ears, including your own fingers, as they may be in contact with fungal spores that are difficult to spot with the naked eye. 
• Keep ears dry: Prevent water from entering the ear canal during water activities by wearing swim plugs or a swimming cap, especially if the water body is poorly maintained or poor hygiene is suspected. Additionally, dry your ears thoroughly after the water activity.
• Avoid scratching your ear: Be careful not to scratch the skin around or inside your ears.

Managing a Fungal Infection in the Ear

Fungal ear infections usually aren’t serious, but they can be uncomfortable and often don’t resolve on their own. Understanding the symptoms, risk factors, and preventive measures can help you better manage and maintain your ear health. If you suspect you have a fungal ear infection, contact your healthcare provider so they can confirm your diagnosis and recommend appropriate treatment for your condition.
