17012 Fungal Sinusitis Fungal Sinus Infection

Overview

Fungal sinusitis is an infection or inflammation of the lining of your sinuses — the small, air-filled spaces in the bones around your nose — that is caused by fungi. Fungi are tiny organisms like molds and yeasts that live in the air, soil, and plants. In most people, fungi don't cause any trouble, but sometimes they can grow in the sinuses and lead to symptoms.

Fungal sinusitis is not as common as viral or bacterial sinusitis. One type, called a fungal ball, is uncommon and usually stays in one sinus. The most serious type, invasive fungal sinusitis, is very rare and almost always happens in people with severe immune system problems.

Anyone can get fungal sinusitis, but the serious type is more likely if you have diabetes, HIV/AIDS, a blood cancer, or if you take certain medicines that lower your immune system. People with asthma or allergies may get a type called allergic fungal sinusitis.

Symptoms

Common symptoms

• Nasal congestion or stuffiness that doesn't go away
• Thick nasal discharge that may be yellow, green, or brown
• Facial pain or pressure, especially around the forehead or cheeks
• Reduced sense of smell
• Headache
• Postnasal drip (mucus dripping down the back of your throat)

Symptoms in children

• Same signs as adults, like stuffy nose and facial pain
• Cough that lingers
• Fussiness or tiredness
• Poor feeding in infants or young children

Symptoms in older adults

• Mild congestion or facial pressure that may be easy to ignore
• A fungal ball may cause no symptoms and be found only on a scan done for another reason
• In serious cases, confusion or drowsiness can occur, especially with a weakened immune system

Causes

Main causes

• Fungi that are common in the environment, like Aspergillus, growing in the sinuses
• Blockages in the sinus passages that trap mucus and create a place for fungi to grow
• A weakened immune system that cannot fight off the fungus effectively

Risk factors

• Weakened immune system from conditions like diabetes, HIV, or cancer
• Taking medications that suppress the immune system, such as long-term steroids
• Chronic sinusitis or nasal polyps
• Allergies and asthma
• Smoking or exposure to secondhand smoke
• Living or working in damp, moldy environments

When to see a doctor

See a doctor urgently if:

• Eye pain, swelling around the eyes, or vision changes
• Severe headache that doesn't improve
• A dark patch inside the nose or on the roof of the mouth
• Symptoms that rapidly get worse, especially if you have a weak immune system

Book a routine appointment if:

• Sinus symptoms that last longer than a week
• Multiple sinus infections in a short period
• Facial pain or pressure that affects your daily life
• A weak immune system and any new sinus symptoms

Diagnosis

Your healthcare provider will ask about your symptoms, look inside your nose with a light, and may use a thin, flexible tube with a camera (called an endoscope) to see your sinus openings. If fungal sinusitis is suspected, they may send you to an ear, nose, and throat specialist (ENT).

Tests that may be done

• Nasal endoscopy — a small camera is placed into the nose to look for signs of fungus
• CT scan of the sinuses — a special X-ray that shows the sinuses in detail
• Blood tests — to check for signs of infection or immune problems
• A sample of nasal discharge or tissue, which is sent to a lab to look for fungi

What to expect at your appointment

The doctor will explain which type of fungal sinusitis you have and what it means for your health. They will then talk with you about the best treatment options based on your symptoms and your overall condition.

Treatment

Treatment for fungal sinusitis depends on the type you have and your general health. Some types only need a minor procedure to remove fungal material, others need medicine to control inflammation, and the most serious type needs urgent surgery and antifungal medicine in the hospital.

Self-care at home

• Use saline nasal rinses if your doctor suggests them — these help wash out mucus and fungi
• Use a humidifier at home to keep the air moist
• Breathe in steam from a bowl of warm water (carefully) to help open your nose
• Drink plenty of fluids to keep mucus thin
• Rest and place warm, damp cloths over your face to ease pain

Medical treatments

Doctors may prescribe antifungal medicines to stop the fungus from growing. For milder types, these may be pills or liquids you take at home. For serious infections, you may need to be in the hospital to receive antifungal medicine through a vein. If inflammation or allergies are part of the problem, steroid medicines may also be used to reduce swelling. Your doctor will decide what is right for you and explain everything clearly.

When is surgery considered?

Surgery is often needed to remove fungal material, open blocked sinuses, or clean out infected tissue. This is especially common for fungal balls and is essential for the invasive form of fungal sinusitis.

Living with this condition

You can continue with your normal daily activities while managing your sinus health. Keep up with any treatments your doctor recommends, and check in regularly with your care team. If you have a chronic condition like diabetes, keeping it well managed also helps your body fight off fungus.

Lifestyle tips

• Avoid smoking and secondhand smoke — these irritate the sinuses
• Keep your home clean and dry to reduce mold
• Change air filters regularly and dust often
• If you work in dusty or moldy places, wear a mask or respirator
• Wash your hands often, especially after touching soil or plants

Diet and exercise

Eating a balanced diet and getting regular exercise can strengthen your immune system. Drink plenty of water throughout the day — this helps thin mucus and keeps your sinuses moist.

Mental health and emotional wellbeing

Living with sinus problems can be frustrating, especially if symptoms last a long time. It's normal to feel tired, anxious, or down. Talk to your doctor about how you're feeling. Reaching out to friends, family, or a counselor can also make a big difference.

Prevention

You can lower your risk by managing health conditions, avoiding smoke, and reducing exposure to mold and dampness. If you have a weakened immune system, talk with your doctor about extra precautions you can take.

Vaccines

There is no vaccine available to prevent fungal sinusitis.

Screening programmes

No routine screening is recommended for the general public.

Complications

If left untreated

• A fungal ball can stay in the sinus and cause blockage, but it usually doesn't spread
• Allergic fungal sinusitis can lead to nasal polyps and more sinus damage if not treated
• Invasive fungal sinusitis can spread to the eyes, brain, or blood vessels and can become life-threatening

Long-term outlook

With prompt and proper care, most people with fungal sinusitis recover well. The milder forms can usually be treated successfully with simple procedures or medicines. The serious form responds much better today than in the past, especially when caught early. Your healthcare team will work with you to give you the best chance of healing.
