Do you also have a stuffy nose all the time? Do you have a heavy head, aches on both sides of your cheeks, your forehead, or the area between your eyes? Most of the time, these can be sinus-related problems. But did you know that not all sinus problems are the same? Some sinus infections are caused by bacteria, some by viruses. But today we are going to talk about a slightly different type of sinusitis that many people are not aware of. That is a sinus infection caused by fungus, or to be more precise, a condition called fungal sinusitis . Sometimes, this is also called fungal rhinosinusitis.
What is Fungal Sinusitis? Let's explain it simply.
Simply put, Fungal Sinusitis is an infection of our sinus cavities due to fungi (i.e. microorganisms such as yeast and mold). The sinus cavities are the empty spaces between your cheeks, forehead, and eyes. There are several types of fungal sinusitis. But most of the time, the common symptoms of all of these types are nasal congestion, mucus, and sinus pain.
Most often, doctors treat this condition with sinus surgery, but in some severe cases, antifungal treatment may be necessary.
What are the main types of Fungal Sinusitis?
Doctors divide fungal sinusitis into two main types:
1. Noninvasive types: These are the most common types. In this type, the infection is limited to the nose and sinus cavities. It rarely spreads to other parts of the body.
2. Invasive types: These are a little more dangerous, but are very rare. In this type, the fungal infection can spread to other parts of the body, for example, the eyes and even the brain. If not treated properly, this condition can be life-threatening.
Now let's look at each of these types in a little more detail.
Noninvasive fungal sinusitis types
- Allergic fungal sinusitis: This is caused by the body's allergic response to fungi in the nose. In this, the sinus cavities fill with thick mucus, and sometimes nasal polyps can develop. People with asthma or allergies such as hay fever are more likely to develop this type.
- Fungal ball / mycetoma: This is when fungi accumulate inside the sinus cavities and form a small ball or mass. This fungal ball (mycetoma) can grow and block the sinus passages.
- Saprophytic fungal sinusitis: This is when fungi grow on crusts of mucus inside the nose.
Types of Invasive Fungal Sinusitis
- Acute invasive fungal sinusitis: In this case, the fungus destroys the blood vessels inside the nose. Then the tissue in that area begins to die. This infection can spread very quickly to the eyes and brain, causing blindness and even death. People with a weak immune system are more likely to develop this condition.
- Chronic invasive fungal sinusitis: This is similar to the acute type, but it spreads a little slower. People with diabetes mellitus are more likely to develop this type.
- Granulomatous invasive fungal sinusitis (GIFS): This is a very rare type. What happens in this is that our body's immune system reacts strongly against the fungus. Then the immune system attacks the lining of the nose, destroying the nasal tissue. Doctors still don't have a clear idea why this happens.
How common are these fungal sinus infections? Who gets them most often?
People with weakened immune systems are generally more likely to develop these fungal sinus infections. Particularly severe infections are more common in:
- For those infected with HIV.
- People with cancer (e.g. leukemia, lymphoma), or those receiving chemotherapy for cancer.
- For people with severely uncontrolled diabetes.
- People taking immunosuppressants, for example steroids.
What are the symptoms of a fungal sinus infection?
The symptoms of fungal sinusitis can sometimes be similar to those of a regular sinus infection. However, whether or not additional symptoms occur depends on the type of fungal infection and whether it is invasive or not.
Typically, noninvasive types exhibit the following characteristics:
- Decreased sense of smell through the nose.
- Fever.
- Swelling of the nose and sinus cavities.
- A thick, sticky substance that may look like rubber glue, usually golden yellow in color, coming out of the nose.
- Nasal congestion.
- Runny nose (phlegm).
- Feeling of pressure and heaviness in the sinus cavities.
- Sinus headaches.
- Only you can smell a bad smell (like a burning smell, the smell of something rotten) that no one else can smell.
People with weakened immune systems are at higher risk of developing severe symptoms such as:
- Behavioral changes and neurological problems (difficulty thinking and reasoning).
- Changes in skin color (maybe the skin color becomes very pale or dark).
- Feeling of numbness in the face.
- Vision changes, possibly even complete loss of vision.
- Severe headache.
- Severe swelling of the cheeks or eyes.
Why does this fungal sinusitis occur? What is the cause?
Sinus infections can be caused by various types of fungi. Most often, these fungal sinus infections are caused by mold or yeast. When we breathe, these tiny fungal particles can enter our sinus cavities through our noses.
Think about it, many of these types of fungi actually live on or inside our bodies all the time. But they usually don't bother us. What becomes dangerous is when our immune system is weakened. Then these fungi can easily grow and cause infections.
What complications can occur if left untreated?
If invasive fungal sinus infections are not treated properly, the fungus can destroy the tissues inside the nose and spread to the eyes and brain. These complications can lead to tissue damage, blindness, and even death . People with conditions that weaken the immune system (e.g., diabetes, leukemia) are especially at risk for these complications.
Therefore, if you have symptoms of fungal sinusitis, especially if you have a weakened immune system, it is very important to seek medical advice immediately.
How do doctors diagnose this condition called fungal sinusitis?
When you go to see a doctor, he or she will first examine you (`physical exam`). He or she will ask about your symptoms, your health history, and the medications you take. Then, they will likely order some tests, such as:
- Endoscopy: This involves the doctor inserting a long, thin tube (with a small camera on the end) into your nose to examine your sinus cavities. The images from the camera can be viewed on a monitor. This is a simple, painless test.
- Biopsy: During the endoscopy, your doctor may take a small sample of mucus or tissue from your nose. This sample is sent to a lab to determine exactly what kind of pathogen is causing your sinus infection — whether it's a virus, bacteria, fungus, or parasite. It can also tell if the infection is invasive.
- CT scan (computed tomography scan): This is like a special X-ray. It can take a very clear look inside your sinus cavities, pinpoint the exact location of the infection, and even check for those fungal balls we talked about earlier.
What are the treatments for this?
There are several treatments for fungal sinusitis. The treatment you need will depend on your condition.
- Antifungals: Some types of infections require antifungal medications. These medications are often prescribed in conjunction with surgery.
- Corticosteroids: Your doctor may prescribe steroids to reduce swelling and lower sinus pressure.
- Nasal wash: In conditions like saprophytic fungal sinusitis, doctors remove the dried mucus from the nose and thoroughly rinse the sinus cavities with a saline solution (a mixture of salt and water).
- Sinus surgery: Depending on the type of infection, the doctor may need to perform a general surgery. This involves removing the infected tissue and cleaning the area thoroughly. If the infection has spread aggressively, this surgery may even remove the affected parts.
Some types of fungal sinusitis may not require major treatment for someone with a healthy immune system. However, invasive fungal sinus infections are a medical emergency and require immediate treatment.
Can this fungal sinusitis condition be prevented?
In fact, it's difficult to completely prevent a fungal sinus infection because fungi are ubiquitous in the environment. However, it's important to talk to a doctor if you fall into one of these risk groups:
- If you have ever had a fungal sinus infection.
- If you have a medical condition that weakens your immune system.
- If you are taking immunosuppressant drugs or are receiving chemotherapy for cancer.
If you have a weakened immune system or are at higher risk for fungal sinus infections, tell your doctor. He or she may prescribe antifungal medications to prevent an infection before it occurs.
What happens if I have fungal sinusitis? Will it get better?
Most noninvasive fungal sinus infections, if treated properly , resolve without any serious complications. However, some types of infections can recur even after treatment.
However, invasive fungal sinus infections are a medical emergency and require immediate treatment.
For example, the condition ``Acute invasive fungal sinusitis`` can be fatal in about 50% of cases if left untreated. Because this infection spreads very quickly, it is essential to get treatment as soon as possible. Even after treatment, some people may develop nerve damage, long-term pain, or facial deformities due to tissue damage.
When should I see a doctor?
If you think you have symptoms of fungal sinusitis, be sure to see a doctor for a checkup. It's also important to tell your doctor if you have persistent sinus problems, such as chronic sinusitis, which doesn't go away.
When should you seek emergency treatment?
If you have symptoms of a fungal sinus infection, and you fall into any of the following categories, go to an emergency room immediately:
- If you have a medical condition that weakens your immune system (e.g. HIV, uncontrolled diabetes, cancer).
- If you are taking immunosuppressant drugs.
Finally, things to remember (Take-Home Message)
When it comes to fungal sinus infections, they can range from mild to severe. Just because you have fungal sinusitis doesn't mean you should panic. But it's important to see a doctor and get proper treatment.
Remember, especially if you have a weakened immune system and you develop symptoms of fungal sinusitis, seek medical attention immediately without delay. As invasive fungal sinus infections can spread very quickly and cause other serious, even life-threatening, complications.
Therefore, the most important thing is to take care of your health.
