Fungal sinusitis diagnostic management and classification
The aim of this paper is to present the current classification of fungal sinusitis and share our experiences in diagnostic procedures and treatment outcomes. The study includes 31 patients operated since 2000-2009. in whome some form of fungal infection had been diagnosed. There were 10 patients with mycetoma, and 16 patients with chronic non-invasive fungal sinusitis, while in five patients allergic fungal sinusitis was proven. All patients were treated postoperatively with topical steroids and irrigation with saline solution, without use of fungicides. Characteristics of chronic non-invasive funga sinusitis and mycetoma are CT with specific opacification and calcification with involement of maxillary sinus unilaterally or bilateral together with pathohistological finding of positive staining by Grocott with the identification of fungi from secret or tissue. Allergic fungal sinusitis is characterized by eosinophilia, positive skin test to fungal allergens, elevated serum level of both specific IgE antibodies to causal fungus and total IgE, as well as, pathohistological finding of allergic mucus which include non-invasive hifa. Fungal sinusitis in immunocompetent patients is classified into the following categories: mycetoma, chronic non-invasive fungal sinusitis, chronic indolent sinusitis (which does not occur in our population) and allergic fungal sinusitis.
