Variants of persistent olfactory dysfunction associated with Novel Coronavirus infection and treatment results

The problem of the occurrence of persistent olfactory dysfunction (OD) associated with Novel Coronavirus infection (COVID-19) has now become relevant, however, a regulated standard of therapy has not been developed. According to the literature, about 60 % of patients report the presence of olfactory disorders that persist for several months or more after recovery from COVID-19. However, no more than 5 % seek medical help for olfactory disorders, which indicates the importance of the problem and the need for treatment in a polyclinic setting. Currently, two main areas of treatment for quantitative and qualitative disorders of the sense of smell are used – drug and non-drug therapy. The article proposes a systematization option based on existing treatment methods with an assessment of their effectiveness. The method of performing olfactory training is described, and the results of treatment of persistent OD are presented.
