Abstrakt:	Objective: To analyze the correlation between nasal mucosal microbiota diversity and the pathogenesis and prognosis of chronic sinusitis. Methods: A total of 80 patients with chronic sinusitis（CRS） admitted to Second Affiliated Hospital of Suzhou University were selected as the research group, and 80 patients with chronic dacryocystitis and nasal septum deviation without sinus inflammation admitted to our hospital during the same period were selected as the control group, nasal secretory specimens were collected under nasal endoscopic guidance by nasal swab, and matrix-assisted laser desorption ionization classification time mass spectrometry, anaerobic bacterial culture and common bacterial culture were performed to compare the differences in nasal mucosal flora between groups. Patients with chronic sinusitis were followed up for 6 months, and nasal secretions were collected again to detect microflora, and the patients were divided into relapse group（21 cases） and non-recurrence group（59 cases） according to whether the patients had relapse. Compare the diversity of nasal microbiota between groups. Results: There were no significant differences in mean relative abundance（MRA） between the two groups of preoperative phylum Microbacterium verrucobacterium, Cyanobacterium phylum, Phylum Laubia mlaus, Porphyromonas species, Enterococcus species, Fusobacterium species, Enterobacter species, Enterobacter species, Erythrobacterium species, Ralstonia species, Bacteroides and Streptococcus species（ P >0.05）. The MRA of Acidobacterium, Proteobacteria, Actinomycetes MRA, Moraxia, Cyanobacterium, Corynebacterium and Staphylococcus were significantly lower than those of the control group（ P <0.05）, and the MRA of Escher-Shigella species, Fusobacterium, Bacteroides, Firmicutes, Neisseria, Pseudomonas, Haemophilus and Lactobacillus was significantly higher than that of the control group（ P <0.05）, and there was no significant difference in MRA at the level of nasal flora and genus before and after surgery in the relapsed group （P >0.05）. The MRA of Bacteroides after surgery was significantly lower in the non-recurrent group than that before surgery（ P <0.05）, the MRA of Corynebacterium and Actinomycetes was higher significantly than that of preoperative（ P <0.05）, and there was no significant difference in MRA of other species and phylum（ P >0.05）. Conclusion: The onset of CRS is related to nasal mucosal dysbacteria, and whether the dysbacteriosis improves after surgery is correlated with the prognosis of patients.
