The symptoms of sinus fungus vary depending on the type of the condition, but sinus discomfort and thick mucus are fairly common, according to the American Academy of Otolaryngology. Four major types of sinusitis involving fungus have been identified as of 2015.
Mycetoma fungal sinusitis manifests with symptoms of discomfort in the sinuses. Clumps of spores generate within a sinus cavity. In many cases, patients have experienced injury or trauma to the sinus with the fungus. Treatment involves scraping the fungus out of the sinus, notes the American Academy of Otolaryngology.
Allergic fungal sinusitis is an allergic response to fungi floating in the air. Many patients with this variety have already suffered from allergic rhinitis, which makes identifying the transformation point to allergic fungal sinusitis difficult. Symptoms are difficult to distinguish from rhinitis, but successful treatment requires surgical removal of fungal debris and mucin in the sinus cavities, reports the American Academy of Otolaryngology.
Fulminant sinusitis presents in patients with immunodeficiency problems, either through a disorder or through use of medications. This condition destroys the sinuses over time and sometimes invades the cavities holding the brain and eyeball. Chronic indolent sinusitis causes chronic headache and gradual facial swelling that eventually threatens vision, as stated by the American Academy of Otolaryngology.
