SummaryIntroduction. . The aim of the study was the analysis of reasons for the occurrence and treatment results of chronic inflammation of the paranasal sinuses in own materail.Material and methods. The study was performed on 520 women aged 18 87 and 789 men aged 19-85, diagnosed and treated for the chronic inflammation of the paranasal sinuses in 2016 2020. The analysis was based on disease medical history, taking into account: gender; age of patients; type of symptoms; allergy diagnosis; probable cause of inflammation; type of anatomical anomalies; assessment of the advancement of lesions based on CT images in the Lund- Mackay scale; number of operations; histopathological result of the removed lesions; complications that occured after surgical treatment.ResultsThe study showed that the hospitalized patients were most often aged 41-50, 51-60 and 31-40 among women and men aged 51-60, 41-50 and 31- 40 . The results of allergological diagnostics among patients with chronic inflammation of the paranasal sinuses showed that women were most often allergic to pyralgin + ketonal + paracetamol + ibuprofen in 4.50 % , to penicillins in 1.07 % and to house dust saprophytes in 0.92%, while among men, positive reactions were found in 3.36 % for pyralgin + ketonal + paracetamol + ibuprofen, 0.99% for house dust saprophytes and 0.92% for cats and dogs fur. Absence of anatomical anomalies was found among 20.75 % of woman and 26.36 % of men, but most often they occurred in the form of nasal septal curvature and excessively dilated middle nasal turbinate. In the histopathological examination of the lesions from the paranasal sinuses, the following were found: chronicinflammation of mucous membrane, chronic polypoid inflammation, chronic cystic inflammation and chronic allergic inflammation.Conclusions. The main symptoms among patients with chronic inflammation of paranasal sinuses were: nasal congestion + rhinorrhea, nasal congestion + rhinorrhea + smell impairment and nasal congestion + rhinorrhea+ headache. The most common probable causes for chronic inflammation of nasal sinuses among the examined patients were: anatomical anomalies, allergies, irritant factors, including tobacco smoke. Depending on the assessment of the severity of changes in the paranasal sinuses according to the Lund- Mackay scale, it appears that medium and large inflammatory lesions prevailed in the examined patients.Key words: reason/cause, occurrence, treatment results, chronic inflammation of the paranasal sinuses
