It's believed that rhinosinusitis (RS) is one of the most desease that has viral etiology. Even though there is a lack of statistical data about what percentage of cases and what kind of virus causes the development of RS.Aims. The purpose of our research was determining the frequency of RS throw out a calendar year and identifying the leading etiological factor and comparing it with the data of circulating of respiratory viruses in the given region.Methods. 316 RS patients were analyzed from January to December 2013 in ENT-department children clinic. For identifying the etiology of RS the aspirate taken from paranasal sinuses was sent for microbiological tests.Results. Patients with RS were 15,6% out of hospitalized. The frequency of RS coinsided with the amount of patients with common cold: maximum in February-March (31%-30,7%), recession in June-August (12,5%- 13,4%-14,4%) and average (16,5% - 23,4%) in other months. Out of 252 punctured sinuses only 141 aspirates were suitable for virological and bacteriological tests. Currently we have received the results of 92 aspirate tests, the other ones are currently being analyzed. In most cases (19,6%) there is a rhinovirus, no tests identified metapneumo- and coronaviruses. Comparing the results of viral and bacteriological research showed the viral RS was determined in 14,1%, bacterial – 33,7%, mixt- 28,3% and undetermined – 23,9%. The most common bacterial agents were Streptococcus pneumonia (29,3%) and Hemophilis influenza (14,1%).Conclusions. The received data of viruses taken from paranasal sinuses coincide with the data of circulation of respiratory viruses in the given region in a certain time period. ER -
