Summary
Introduction:Chronic rhinosinusitis (CRS) is an inflammatory process affecting the mucosa of the nasal cavities and paranasal sinuses. The inflammation lasts more than 4-6 weeks. The aetiology of CRS is multifactorial. A number of conditions predispose to rhinosinusitis, among others microbial infection.
Aim: To evaluate the bacteriological testing of samples taken from the middle nasal turbinates and lumen of maxillary sinuses of children operated on for chronic rhinosinusitis.
Material and method: The research included 139 children, treated surgically in the Department of Paediatric Otolaryngology, Warsaw Medical University between 2007 and 2009. The material for bacteriological examination was collected during endoscopic sinus surgery from the middle nasal turbinates and maxillary sinuses.
Results: Two diagrams presented below show the most frequent pathogens co-existing with chronic rhinosinusitis in the examined group. Both in the material from the maxillary sinuses and from the middle nasal turbinates Staphylococcus spp. coagulase(-) was cultured most frequently.
Discussion: Chronic rhinosinusitis develops as a result of a composite and multistage inflammatory process. At least one component of the pathogenesis of CRS is bacterial infection. In our research in fairly many cases we have noticed a lack of correlation between the results from the nasal turbinates and from the maxillary sinuses.
Conclusions: 1. The results of bacteriological testing in the examined group differ from the most common aetiology that causes rhinosinusitis described in the literature. 2. The results taken from the middle nasal turbinate in most cases differ from the results taken from the lumen of the maxillary sinuses. 3. Examination of samples taken from the middle nasal turbinates and maxillary sinuses play a vital role in establishing the aetiology of rhinosinusitis and in choosing the exact treatment in case of recurrence of rhinosinusitis.
