Background and objective: With respect to the correct diagnosis of pathological and microbiological agent as chronic rhinosinusitiscreator and predisposing factors, this study performed by the objective to determine Pathological and microbiological of maxillary sinus in chronic sinusitis by Functional Endoscopic Sinus Surgery. Material and Methods: In this cross-sectional study the FESS specimens were collected from 94 patients with rhino sinusitis with inclusion criteria and was studied in terms of bacteriology and pathology.Collected data were analyzed using descriptive tests, Chi- Square by the 16 version SPSS software.The significance level of the test was considered to be less than 0.05. Results: In this study, out of 94 samples, bacterial growth was reported in 53 samples (56.4%).Staphylococcus epidermis in 12 cases (12/8%), Staphylococcus aurous in 11 cases (11/7%) and Enterobacter in 10 cases (10/6%) were the most common. There was a statistically significant difference between the growth or non-growth of bacteria and the species of bacteria (gram positive, gram negative) with allergies (P = .003). Nasal polyp was observed in 92 (97.9%) in Pathological analysis. Not significant difference between growth and no growth of bacteria also between species of bacteria with pathological specimens. Conclusion: In this study gram positive bacteria’s were the most common bacterial growth in culture. The variability of the results from studies may be due to the different techniques used as collection method, variation in culture methods, previous antibiotic therapy, and difficulty in distinguishing bacterial flora from pathogenic agent.
