New tools for preoperative diagnosis of allergic fungal sinusitis? A prospective study about 71 patients

Abstract : Allergic fungal sinusitis (AFS) is a subgroup within noninvasive fungal chronic rhinosinusites. Its paraclinical diagnosis is based on a « gold standard »: rhinosinusitis evolving for at least 12 weeks or persisting on CT scan, allergic mucin seen during surgery, identification of Charcot‐Leyden crystals or eosinophils aggregates in pathology, fungal hyphae on direct examination or culture. Our objective was to search for clinical, radiological, biological, immunological and mycological criteria permitting AFS preoperative diagnosis, within a population operated on for CRS.
