OBJECTIVE: To determine the distribution of bacteria in patients with chronic rhinosinusitis, and to compare the bacteriologic features in middle meatus specimens between patients with nasal polyps (CRSwNP) and patients without nasal polyps (CRSsNP).
METHODS: We retrospectively analyzed the positive rate and types of bacterial culture in middle meatus specimens from 40 controls, 65 patients with CRSwNP, and 72 patients of CRSsNP. The specimens from the middle meatus were obtained during endoscopic sinus surgery.
RESULTS: The positive rates of bacteria for CRSwNP, CRSsNP and the controls 81.9%, 80.0% and 82.5%, respectively, with no significant difference among the 3 groups. The common aerobe bacteria found in the specimens was Coagulase-negative staphylococci, Staphylococcus aureus, Streptococcus and Corynebacterium. The common anaerobe was Fusobacterium. The positive rates for aerobic and anaerobic bacteria showed no significant differences among the 3 groups.
CONCLUSION: The distribution of bacteria in middle meatus specimens is not significantly different among CRSwNP, CRSsNP and the controls. Therefore, bacterial infection may not play a key role in the pathogenesis of CRS patients with and without nasal polyos.
