The combination of factors, such as abnormal viscosity of the paranasal sinus secretions, decreased sinus drainage, and impaired mucociliary clearance may account for the establishment of a suitable and opportune environment for the colonization of bacteria in the paranasal sinuses of patients with cystic fibrosis. AIM: The goal of the present study was to assess the bacteriology of the middle meatus aspirate in patients diagnosed whit cystic fibrosis. MATERIAL AND METHODS: Through a cross-sectional prospective study, a sample consisting of 23 patients evaluated for 2 years, was assessed. Firstly, we established the relationship between the middle meatus culture and the maxillary sinus x-ray. In second, we studied the relationship between the middle meatus aspirate bacteriology and the sputum bacteriology. RESULTS: In total, 42 aspirates of the middle meatus were carried out. In 17 (73.91%) of the 23 patients, the aspirates were negative; and in 6 (26.08%) they were positive. Out of the 42 aspirates,31 (78.8%) were negative, and 11 (26.2%) were positive. The presence of Pseudomonas aeruginosa was observed in 18.18% of the positive cultures, and Staphylococcus aureus was observed in 27.28%. CONCLUSION: The great majority of the middle meatus aspirates of the patients with cystic fibrosis were negative.
