In the present context of the COVID-19 pandemic, the olfactory dysfunctions (OD) in patients that are positive for SARS-CoV-2 have been more intense and of early emergence, which is the reason why it is important to study the olfactory function in these patients.

The purpose of this study was the evaluation of the olfactory dysfunction measured through threshold and olfactory discrimination tests (Connecticut). The research was carried out at the Respiratory Hospital of the Santa Casa de Belo Horizonte and included 99 patients infected with SARS-CoV-2, who were evaluated from July 2020 to February 2021. The olfactory test showed that 66% of the patients had some degree of hyposmia in the right nasal cavity and 69,1% in the left nasal cavity. The ages ranged from 19 to 86 years old and the average age was 58.7 years old (+-14.5). When comparing gender and age (< = 60 years old and > 60 years old) in relation to the highest degree of hyposmia, it was possible to verify that the gender variable (male VS. female) did not show a significative difference in hyposmia, p = 0.845. In relation to age, it was possible to see a statistically significant difference, p = 0.003. Patients under the age of 60 showed a higher proportion of normality, followed by mild and moderate hyposmia when compared to those aged 61 and over. The proportion of severe hyposmia/anosmia was higher in those aged 61 and over.
