    ¡¾Abstract¡¿ AIM: To make a preliminary analysis about the fungi in the microecosystem of ostiomeatal complex. METHODS: Forty patients were grouped into S and P; else with 20 control subjects (N). Asepticly, swab speciemens were taken from three different sites in ostiomeatal complex on each individual (totally 180 sites) and sent for fungus culture. Positive culture rate, same culture rate of fungi(SCRF) and predominant species were surveyed. Concurrently, 37 cases with a final diagnosis of fungal sinusitis were reviewed. RESULTS: Positive rate in N, S, P was 10%, 30%, 15%£¬and SCRF was 90%, 70%, 85% respectively; Differences between the 3 groups were not significant either (P>0.05). Aspergillus, Penicillium were the predominant species. Almost all that found from the 37 reviewed cases were Aspergillus , and mainly located in maxillary sinuses. CONCLUSION: Under condition that of normal status or nonfungal chronic sinusitis, the role of fungi in the microecosystem of ostiomeatal complex is rather limited and it¡¯s by no means able to evaluate the status and alternations of the certain microecosystem. ......
