How to treat fungal sinus infections

Updated February 21, 2017

There are three major types of fungal sinus infections; the fungal ball, allergic fungal sinusitis and invasive fungal sinusitis, all of which mimic the symptoms of a less-serious regular sinus infection. If left untreated, fungal sinus infection could lead to recurring sinus blockage and repeat infections. The more invasive types of fungal sinus infection could result in death.

Visit your doctor and undergo examination. Your doctor need to diagnose your condition and testing will be required to determine the type of fungal infection you have. Each of the three types of fungal sinus infection require specific types of treatment.

Diagnosing a fungal ball infection may require you to undergo X-rays, a CAT scan or an MRI, as the symptoms are similar to a regular sinus infection. Recurring symptoms and infections will prompt further testing. If a fungal ball infection is discovered, non-invasive endoscopic sinus surgery is required to remove the fungus.

Symptoms of allergic fungal sinusitis are similar to bacterial sinusitis and may include polyps inside the nose and heavy mucus discharge. Treatment begins with topical steroids, anti-fungal medication and rounds of antibiotics. In the event that early treatment tactics fail, allergy immunotherapy and sinus irrigation are attempted. If none of the aforementioned treatments affect the infection, endoscopic sinus surgery may be the only solution. Unfortunately, allergic fungal sinusitis is often a lifelong malady that can be treated and managed, but not always cured.

Surgery and anti-fungal treatment are required for invasive fungal sinusitis, which has a high mortality rate if left untreated. Untreated invasive fungal sinusitis can spread beyond the sinuses, invading bone and facial tissue. In the event of a serious bodily infestation, bone and tissue may have to be removed to prevent reinfection.

Prevention is a key element in treatment with any type of fungal sinus infection. Making sure your home is kept dry through use of a dehumidifier in damp areas like basements and garages will help cut down on mould and other fungi. You can also run an electric air purifier in your home to trap and filter mould, mildew and other airborne fungi.


If you suspect that you may be suffering from a fungal sinus infection, see your doctor immediately for diagnosis to avoid major complications.
