The article presents the prevalence of chronic tonsillitis (CT) in children, adolescents and adults in the northern region of
Russia (Tyumen region) over the past 4 years (2015-2018). It was shown that in all studied groups the incidence of chemotherapy
is 3 times higher in children and 2 times higher in adolescents in the national districts of the region. The incidence among adults
throughout the region varies in the same numbers. An analysis of 106 outpatient charts of patients with chemotherapy revealed that
only 20.8% of patients had a history of previously experienced sore throats, more often patients were concerned about discharge
from lacunar plugs with an unpleasant odor (64.2%) and discomfort in the throat with prolonged subfebrile condition (83, 3 and
87.7, respectively). In 21.7% of patients, a recurrent paratonsillar abscess was verified without a history of angina.
