SUMMARY
Background. At present, compared to the period before the COVID-19 pandemic, there is a noticeable increase in hospitalization cases among patients presenting with disorders of the ENT organs, particularly nasal functions. The aim: to determine the prevalence of nasal diseases among patients who had had COVID-19. Materials and methods. The study included 392 patients with nasal diseases. All patients had previously had COVID-19. Results. 32.4% of patients were diagnosed with rhinitis, 27.6% with a deviated septum, 9.7% with sinusitis, 5.9% with adenoid vegetation, and 4.3% with nasal polyposis. A combination of diseases was observed in 20.1% of patients, of whom 17.3% had two diseases and 2.8% had three diseases. Acute rhinitis was observed in 3.3% of patients, chronic rhinitis in 29.1%: allergic rhinitis (19.4%), vasomotor type (8.9%), hyperplastic type (0.8%). Acute sinusitis was observed in 1.0% of patients, chronic sinusitis in 8.7%. Hyperplastic sinusitis was observed in 8.9% of patients, purulent sinusitis in 0.8% of patients who sought medical attention. Conclusion. Patients who have had COVID-19 most often develop chronic inflammatory diseases of the nose and associated pathologies. This underscores the need for early diagnosis and comprehensive treatment aimed at preventing complications and improving quality of life.
Keywords: ENT diseases, nasal diseases, COVID-19
