The objective of the present study was to undertake the statistical analysis of the methods employed to treat tonsillitis in the children with a view to optimizing adequate dispensary observation, planned conservative therapy and surgical treatment of the patients presenting with chronic tonsillitis. The analysis of the excerpts from the annual reports presented by the head of the otorhinolaryngological department of the Children's City Clinical Hospital No 9 involved the patients admitted for the pre-planned and urgent treatment of paratonsillar abscess between 1990 and 2010. It was shown that the number of children with paratonsillar abscess increased during this period from 5.8 to 12.0%. At the same time, the number of such patients undergoing surgery for the treatment of toxico-allergic forms (TAF-I and TAF-II) decreased from 26.7 to 8.7-11.6% of their total number admitted to the department for the treatment of pharyngeal pathology. These diseases developed in the children frequently ill with chronic tonsillitis after its recurrent exacerbations. Importantly, all these children were registered in the dispensaries of district out-patient clinics at the places of residence and repeatedly underwent courses of conservative therapy of chronic tonsillitis that either resulted in the temporary improvement of their health conditions or produced no effect whatever. Nevertheless, no district otorhinolaryngologist recommended tonsillectomy to a child with chronic tonsillitis. It is concluded that adequate regular medical check-ups in combination with the planned courses of conservative treatment and hospitalization of the patients in due time for the surgical treatment (tonsillectomy) permit to reduce the frequency of complications of such an insidious disease as chronic tonsillitis.
