Quick Answer: What is a fungal ear infection, or otomycosis?
A fungal ear infection, or otomycosis, is the growth of fungi, mainly Aspergillus and Candida, in the outer ear canal. It causes intense itching, pain, discharge and a feeling of fullness. Moisture and loss of protective earwax raise the risk. It is treated with professional cleaning and antifungal drops, not antibiotics, and usually lasts about three weeks with treatment. [3]
What the research says
Aspergillus is the leading cause, followed by Candida. A meta-analysis of 20 studies (1,392 fungal isolates) that used molecular identification found Aspergillus in 75.8% (95% CI 70.3% to 80.6%) and Candida in 15.3% (95% CI 8.7% to 25.6%) of otomycosis cases. The authors rated the quality of the included studies as poor (Nazari et al., BMC Infectious Diseases, 2025).
Topical antifungals clear most infections, but no single agent is proven best. A meta-analysis of 15 randomized trials (2,309 patients) found an average eradication rate of 73.6%, ranging from 29.0% to 98.3% across commonly used drugs such as clotrimazole, miconazole and fluconazole. Side effects were low, mainly ear pain, itching and burning, and the authors note there is no consensus on the most effective agent (Hussain et al., Otology and Neurotology, 2026).
Understanding Fungal Ear Infections
A fungal ear infection usually involves the ear canal, the tube that starts at the outer ear and ends at the eardrum. It is caused by fungi such as Aspergillus and Candida. Other names for the condition are otomycosis and fungal otitis externa [3].
Ear fungal infections are more likely when temperatures are warm and the air is humid, and they are more common in people who swim or take part in other water sports. These infections usually don't go away without treatment [3].
Feature | Description |
|---|---|
Clinical names | Otomycosis, fungal otitis externa |
Main location | The ear canal (the outer ear canal leading to the eardrum) |
Most common cause | Aspergillus, about 90% of cases according to Cleveland Clinic |
Second most common cause | Candida, which causes most of the rest |
Contagious? | The infection isn't, but the fungus can spread in infected water |
Symptoms and Identifying Signs
Symptoms vary but may include [3]:
Intense itching, pain or burning in the ear
Discharge that is yellow, green, black, white or gray
Flaky skin around the ear canal
Ringing in the ears (tinnitus)
A feeling of fullness or hearing loss in the affected ear
The type of fungus can change what a provider sees. With Aspergillus, you may see yellow or black dots and fuzzy white patches in the ear canal. With Candida, the signs include a thick, creamy white discharge [3].
Causes and Risk Factors
Earwax protects the ear canal and gives it a water-resistant lining, so anything that reduces earwax makes fungal ear infections more likely. Sometimes the infection develops after antibiotic treatment for a bacterial ear infection, because the medicine can also kill the good bacteria that help keep fungus in check [3].
Risk factor | Details |
|---|---|
Water exposure | Scuba diving, swimming, waterskiing, surfing and other water sports |
Ear hygiene | Using cotton swabs or other instruments to clean earwax |
Skin conditions | Ear eczema or other skin conditions affecting the ear |
Immune health | A weakened immune system |
Injury | Ear injuries and trauma |
Climate | Living in a hot, humid area |
Complications
Fungal ear infections aren't usually serious, but they can spread and worsen if left untreated, especially in people with a weakened immune system or a chronic skin condition. Possible complications include meningitis, mastoiditis and, rarely, life-threatening fungal osteomyelitis. Treating the infection early reduces the risk of spread [3].
How Fungal Ear Infections Are Diagnosed
A healthcare provider looks into your ear with an otoscope, a handheld magnifying device. Sometimes they can identify a fungal infection just by looking. They may also swab the ear for fluid or discharge and send the sample to a lab, which shows whether bacteria or a fungus is causing the infection [3].
Treatment and Management
Treatment | What it involves |
|---|---|
Professional cleaning | Special rinses remove discharge and other debris from the ear |
Antifungal ear drops | Drops such as fluconazole or clotrimazole; aluminum acetate or acetic acid drops may reduce inflammation |
Oral medicines | Antifungal medicines such as itraconazole, plus over-the-counter pain relievers for discomfort |
Creams and ointments | For the outer part of the ear: clotrimazole, ketoconazole or econazole |
Home remedies
Some home remedies can ease symptoms, such as diluted hydrogen peroxide to help remove discharge and buildup, carbamide peroxide ear drops, or a 1:1 mixture of rubbing alcohol and white vinegar. Always talk to a healthcare provider before trying any treatment at home [3].
What to avoid
Use cotton swabs only on the outside of the ear. A swab in the ear canal can cause damage and push the fungus deeper. Avoid water sports during treatment, because going back to swimming before the ear has healed can bring the infection back [3].
Outlook and Prevention
Most fungal ear infections last about three weeks. Most people respond well to antifungal treatment, and prompt care usually avoids long-term problems. Take all prescribed medicine for as long as your provider tells you, even if your ear feels better, because stopping early can allow the infection to return and be harder to treat. If you have a weakened immune system, the infection could linger or come back [3].
You may not be able to prevent every fungal ear infection, but you can lower your risk [3]:
Use earplugs when swimming, surfing or doing other water sports.
Dry your ears with a hairdryer after showering, on a low, cool setting.
Avoid scratching the inside of your ears.
Never insert cotton swabs, hairpins or other objects into the ear canal.
When to See a Healthcare Provider
Fungal ear infections don't usually go away without treatment, so contact a healthcare provider if you have ear pain, itching, discharge or other symptoms. If you are already being treated, call your provider if you develop severe pain, dizziness or fever, which can be signs that the infection is spreading or getting worse [3].
Conclusion
A fungal ear infection is uncomfortable but usually not serious, and it responds well to treatment. Recognizing early signs such as intense itching and unusual discharge, and getting professional care, helps you recover faster. Keeping your ears dry and avoiding cotton swabs are the most practical ways to prevent it from returning [3].
Your next step: if you have ear itching, pain or discharge, book an appointment with a healthcare provider rather than cleaning the ear yourself.
Frequently Asked Questions
What exactly is a fungal ear infection?
A fungal ear infection, or otomycosis, happens when fungi such as Aspergillus and Candida grow and spread in the ear, most often in the ear canal. It is also called fungal otitis externa, and it usually doesn't go away without treatment. [3]
Is ear fungus contagious?
The infection itself isn't contagious, but the fungus that causes it can spread from person to person while swimming in infected water. [3]
Can I treat ear fungus at home with cotton swabs?
No. Use cotton swabs only on the outside of the ear, never inside the canal. A swab can damage the ear and push the fungus deeper. Professional cleaning by a healthcare provider is the safe way to remove debris. [3]
Why are fungal ear infections more common in the summer?
Fungi thrive in warm, humid conditions, and people swim and take part in water sports more in hot months. In the United States these infections are most common in summer. [3]
How do I know if my ear infection is fungal or bacterial?
Sometimes a provider can tell just by looking inside your ear with an otoscope. If not, they can send a swab of ear fluid or discharge to a lab to confirm whether bacteria or a fungus is the cause. [3]
What is the most common treatment for otomycosis?
Treatment can include professional cleaning, antifungal ear drops such as clotrimazole or fluconazole, oral antifungal medicines and creams for the outer ear. A meta-analysis of 15 trials (2,309 patients) found an average eradication rate of 73.6% with commonly used treatments. [3][2]
How long does it take for a fungal ear infection to clear up?
Most fungal ear infections last about three weeks. Take all prescribed medicine for as long as your provider tells you, even if your ear feels better, or the infection can come back and be harder to treat. [3]
Can a fungal ear infection cause hearing loss?
Hearing loss and a feeling of fullness are symptoms of the infection. With prompt care, fungal ear infections usually don't cause long-term issues, but untreated infections can spread. [3]
Are there home remedies for ear fungus?
Some people use diluted hydrogen peroxide, carbamide peroxide ear drops or a 1:1 mixture of rubbing alcohol and white vinegar to ease symptoms, but always talk to a healthcare provider before trying any treatment at home. [3]
Who is at the highest risk for ear fungus?
People who swim or do other water sports, use cotton swabs or other tools to clean their ears, have a weakened immune system, have ear eczema or other skin conditions, have had ear injuries or live in a hot, humid area. [3]
