Maxillary sinuses microbiology from patients with chronic rhinosinusitis.

Unlabelled: There isn't definitive and consistent data concerning the distribution of bacterial species in patients with Chronic Sinusitis (CS). The variability of the results from studies in CS may be due to the different techniques used as collection method, variations in culture methods, previous antibiotic use, and difficulty in distinguishing bacterial flora from pathogenic agents.

Study Design: Clinical prospective.

Comparing different methods used to collect material for a microbiological evaluation of patients with chronic rhinosinusitis.

Unlabelled: There is still controversy on which is the best method to collect the secretion directly from the middle meatus or maxillary sinus in patients with chronic rhinosinusitis.

Aim: To evaluate the prevalence of bacteria in patients with chronic rhinosinusitis and compare the suction trap collector to direct aspiration attached to a syringe for the microbiological analysis of these secretions.

Materials And Methods: Prospective study involving 31 patients who underwent endoscopically guided maxillary secretion aspiration by two different methods (aspiration with the collector tube "suction trap" and aspiration with the use of a catheter connected to a syringe), to determine the microbiological diagnosis and to compare the two methods used.
