A combinação de fatores como viscosidade das secreções dos seios paranasais, diminuição da drenagem sinusal e comprometimento do transporte mucociliar podem ser responsáveis pela criação de um ambiente propício e adequado para a colonização de bactérias nos seios paranasais de pacientes com fibrose cística. OBJETIVO: Analisar a bacteriologia do aspirado do meato médio de pacientes portadores de fibrose cística. MATERIAL E MÉTODO: Através de um estudo prospectivo de delineamento transversal, avaliou-se uma amostra composta de 23 pacientes, avaliados durante 2 anos. Realizaram-se relações entre a cultura do meato médio e a avaliação radiológica do seio maxilar e a avaliação clínica. Secundariamente, estudou-se a relação da bacteriologia do aspirado do meato médio e a do escarro. RESULTADOS: No total foram realizadas 42 aspirações do meato médio. Em 17 (73,91%) dos 23 pacientes, as culturas foram negativas e, em 6 (26,08%), positivas. Das 42 aspirações, 31 (73,8%) foram negativas e 11 (26,2%), positivas. A presença de Pseudomonas aeruginosa foi observada em 18,18% das culturas positivas e o Staphylococcus aerus em 27,28%. CONCLUSÃO: A maioria das culturas do aspirado do meato médio de pacientes com fibrose cística foi negativa. 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
