The Sinus Fungal Infection
The Mayo Clinic has conducted studies demonstrating an association between sinus fungal infection and chronic sinusitis. Nasal steroidal sprays destroy the good flora of the nasal cavity, which predisposes one to a fungal infection of the sinus. One such study looked at the ability to test for sinus fungal infections in 54 patients who had a history of chronic sinusitis. Researchers found that with one of the testing methods, 100 percent of participants tested positive for fungus, while with another testing method, 76 percent showed signs of fungus.
