Background. The role of abnormal pharyngeal tonsil (PT) in the pathogenesis of Eustachian tube dysfunction is one of the most urgent problems of otitis media with effusion (OME) in children. Objective: to reveal trends in the visit rates of children with OME in relation to season and the state of PT. Material and methods. The materials of this study are based on the analysis of the rates of children's visits to the ENT Unit, Atlant-Med Clinic (Almaty, Kazakhstan) in 2010-2012. There were a total of 1116 patients with OME, including 665 boys and 451 girls who visited the clinic during this period. Of them, there were 215 (19.3±1.2%) children less than 3 years of age, 753 (67.4±1.4%) children aged 3-6 years, 119 (10.7±0.9%) aged 7-10 years, and 29 (2.6±0.5%) aged 11-14 years. The diagnosis was verified by routine ENT examination supplemented by otoendoscopy and tympanometry. Results. Grade 2-3 PT hypertrophy was encountered in the absolute majority of children with OME. In patients with the bilateral process, PT hypertrophy was recorded more frequently than in children without this conditon. The visit rates in the children with by OME and PT hypertrophy were statistically higher in autumn months than in spring and summer (p<0.01) and were not significantly different from those in winter (p>0.05). In the region in question, sharp weather fluctuations in autumn and winter had a negatively impact on the state of compensatory-adaptive mechanisms in patients with PT hypertrophy and chronic adenoiditis, on the incidence and seasonal prevalence of inflammatory diseases of the upper airways and ear, OME in particular.
