Introduction. Intracranial complications (IC) of sinusitis and acute otitis media (AOM) in children are rare but life-threatening phenomena. Both intracranial and extracranial complications require early diagnosis and timely interdisciplinary approach to treatment. The article considers data on the prevalence of otorhinogenic complications in children, the possibilities of their early diagnosis, treatment and prognosis at the present stage.Aim. To study the prevalence of otolaryngogenic complications, the possibility of their early diagnosis and prediction of the occurrence of complications in children.Materials and methods. A retrospective analysis of medical records of patients aged ≤ 18 years who were treated in the pediatric otolaryngology department of the Tyumen Regional Clinical Hospital No. 2 from 2013–2023 was performed. A patient database was created, the prevalence of intracranial complications was studied, the significance of clinical, laboratory parameters, and integral blood indices was assessed, and a model for predicting otolaryngogenic intracranial complications was created based on the logistic regression method.Results. A total of 21 495 people were treated over the past period, 233 (1.1%) had verified otogenic complications, 55 (0.3%) had intracranial complications, and 178 (0.8%) had extracranial complications. The average age of children with otogenic intracranial complications (OIC) was 6.3 ± 4.1 years, and rhinogenic intracranial complications (RIC) was 11.3 ± 4.5 years. With Ht ≤ 34.2 and ISL ≥ 3.98, OIC is diagnosed, and with ISL ≥ 4.75, RIC is diagnosed, requiring surgical treatment by an ENT doctor and a neurosurgeon. Using logistic regression, a model for predicting complications was created, the sensitivity of which was 97.6%, specificity – 94.0%, and efficiency – 95.6%. The first-line antibiotic therapy used was penicillin group drugs, including combination drugs with clavulanic acid, as well as cephalosporins.Conclusions. The prevalence of otorhinogenic intracranial complications in children of the Tyumen region was 0.3%. Early diagnostics, prognosis, otorhinogenic complications using integral blood indices and logistic regression is a modern and informative method in pediatric practice. The use of amoxicillin in the form of dispersible tablets as a starting antibacterial therapy in children with uncomplicated acute otorhinolaryngitis has good efficiency due to high bioavailability.
