Ear Fungus: Causes, Symptoms, Diagnosis, and Treatment Methods

Ear fungus, medically known as Otomycosis, is a fungal infection that can affect the external or internal parts of the ear. This condition commonly develops in warm and humid environments and is more frequently seen in individuals living in tropical regions or those who are regularly exposed to moisture in the ear. In this article, we discuss the causes, symptoms, diagnostic methods, and treatment options for ear fungal infections.

Causes of Ear Fungus

Ear fungus usually occurs due to the abnormal growth of fungi within the ear environment. Some of the most important factors contributing to this infection include:

Excessive Moisture and Sweating

A moist environment provides ideal conditions for fungal growth.
Swimmers, divers, and individuals who are frequently exposed to water are at higher risk of developing this infection.

Poor Ear Hygiene

Excessive cleaning of the ear using cotton swabs or other tools can disrupt the natural ear flora and facilitate fungal growth.
Additionally, residual soap or cleansing agents left in the ear after bathing may create favorable conditions for fungal proliferation.

Use of Contaminated Devices

Using contaminated earphones, hearing aids, or earplugs can transfer fungi to the ear.
Sharing these devices with others further increases the risk of infection.

Weakened Immune System

Individuals with conditions such as diabetes, HIV/AIDS, or cancer, or those taking immunosuppressive medications, are at a higher risk of developing ear fungal infections.

Frequent Use of Antibiotics and Ear Drops

Prolonged use of antibiotics may eliminate beneficial bacteria in the ear, creating an environment that promotes fungal growth

Ear Fungus Symptoms

Ear fungus (otomycosis) may be asymptomatic in its early stages, but as the infection progresses, a person may experience the following symptoms:

Severe itching in the ear

One of the most common signs of ear fungus is persistent and irritating itching inside the ear.

Abnormal ear discharge

Ear discharge may be white, yellow, brown, green, or even black in color.
These discharges may have an unpleasant odor.

Feeling of fullness and blockage in the ear

The person may feel that the ear is blocked and may not hear sounds properly.

Temporary hearing loss

Blockage of the ear canal due to fungal discharge can lead to temporary hearing loss.

Ear pain or discomfort

In advanced cases, ear fungus can cause inflammation and pain in the ear area.

Dizziness and imbalance

If the infection spreads to the inner ear, the person may experience dizziness and balance problems.

Methods of Diagnosing Ear Fungus

To diagnose otomycosis, the physician typically employs several methods. First, a physical examination of the ear is performed, during which the doctor uses an otoscope to inspect the inside of the ear for signs of fungal infection, discharge, or inflammation. Second, sampling and microscopic examination may be conducted, where a small sample of ear discharge is collected and analyzed in a laboratory to determine the specific type of fungus. Finally, the physician reviews the patient’s medical history, including any underlying diseases, medications, and environmental factors that may contribute to the infection. These steps together help ensure an accurate diagnosis and guide appropriate treatment.

Methods of Treating Ear Fungus

Ear cleaning

The doctor removes fungal debris and infectious discharge using special methods such as microsuction or ear irrigation.

Antifungal medications

Antifungal ear drops:

such as clotrimazole, natamycin, or fluconazole.

Antifungal ointments:

used to reduce inflammation and infection.

Oral antifungal tablets:

in severe cases, oral medications such as fluconazole or itraconazole may be prescribed.

Use of warm compresses

Warm compresses can help reduce pain and inflammation.

Avoiding moisture and water

Until complete recovery, swimming, prolonged showers, and water entering the ear should be avoided.

Strengthening the immune system

Consuming nutritious foods, vitamin C, and reducing stress can help speed up recovery.

Prevention of Ear Fungus

To prevent ear fungal infections, it is recommended to follow a set of simple and effective measures. First, it is essential to keep the ears dry. After bathing or swimming, gently dry the ears with a clean towel, and if necessary, use a hairdryer on a low heat setting to avoid damaging the ear.

Second, it is important to avoid excessive ear cleaning, as overusing cotton swabs or other cleaning tools can disrupt the natural balance of bacteria and fungi in the ear, increasing the risk of fungal infection.

Third, do not share personal items such as headphones, hearing aids, or earplugs with others, as this reduces the chance of transmitting fungi.

Fourth, strengthen the immune system by taking vitamins, exercising regularly, and reducing stress, as a strong immune system helps resist fungal infections.

Finally, use ear medications with caution, avoiding prolonged or continuous use of antibacterial ear drops without a doctor’s prescription, to minimize irritation and prevent creating an environment conducive to fungal growth.

Home Remedies for Ear Fungus

Some home remedies can help reduce the symptoms of ear fungus, but they should not replace medical treatment. The following methods can be effective in controlling and reducing symptoms:

Apple cider vinegar:

A mixture of apple cider vinegar and water (1:1 ratio) can help reduce fungal growth. Using a clean cotton swab, gently apply the solution around the ear.

Tea tree oil:

The antifungal properties of this oil can help eliminate the infection. Mix a few drops with coconut oil and apply it to the outer ear area.

Garlic and olive oil:

Garlic has antifungal properties. Warm a few cloves of garlic in olive oil, and after cooling, put a few drops into the ear.

Warm compress:

A warm compress can help reduce itching and inflammation in the ear.

Note:
If symptoms are severe or persistent, consult a doctor and avoid using home remedies without professional advice.

Symptoms of Ear Fungus

Ear fungus can present with various symptoms depending on the severity of the infection. The most important symptoms include:

• Severe and persistent itching in the ear
• Abnormal ear discharge (white, yellow, green, or black)
• Feeling of fullness and ear blockage
• Temporary hearing loss
• Pain or inflammation in the ear canal
• Unpleasant odor from the ear
• Dizziness and balance problems (in severe cases)

If you experience these symptoms, it is recommended to see a doctor as soon as possible.

Ear Fungus Behind the Ear 

Sometimes, fungus can also grow behind the ear. This problem usually occurs due to moisture, excessive sweating, poor hygiene, or the use of contaminated items such as headphones or ear masks.

Symptoms of fungus behind the ear:

• Flaking and dryness of the skin
• Itching and redness behind the ear
• Fluid discharge or skin inflammation
• Burning sensation or tenderness to touch

Treatment of fungus behind the ear:

• Regular washing with antifungal soap
• Using antifungal creams such as Clotrimazole or Miconazole
  
• Keeping the area behind the ear dry, especially after showering or exercising
• Avoiding frequent use of contaminated items like headphones

When to See a Doctor

It is essential to consult a doctor if you notice any of the following:

• Severe ear pain that is not relieved by painkillers
  
• Severe or persistent hearing loss
  
• Purulent discharge and foul odor from the ear
• Recurrent ear fungus even after treatment

Conclusion

Ear fungus is a common but treatable infection, mostly seen in warm and humid environments. By maintaining ear hygiene, avoiding contaminated water, and using proper medications, the occurrence and recurrence of this infection can be prevented. Early consultation with a doctor upon noticing symptoms can prevent disease progression and potential complications.
