Objective: This study aimed to investigate the nasal findings in patients who tested positive for the coronavirus disease 2019 (COVID-19) and objectively evaluate the amount of nasal secretion and nasal clearance.

Methods: The study included 40 patients who tested positive and 40 volunteers who tested negative for COVID-19 infection. The self-administered Turkish version of the sinonasal outcome test -22 (SNOT-22) questionnaire was used to evaluate the sinonasal findings, the nasal Schirmer test was used to evaluate the amount of nasal secretion, and the saccharin test was used to evaluate nasal clearance. The results of both groups were compared.

Results: The SNOT-22 score averages were 23.3±14.5 and 11.2±11.7 for the COVID-19-positive group and COVID-19-negative controls, respectively. In the COVID-19 positive group, SNOT-22 results were statistically significantly higher than those of the controls (p≤0.001). The nasal Schirmer and nasal saccharin test results in the COVID-19-positive group were statistically significantly higher than those of the controls (p≤0.002 and p≤0.001).

Conclusion: In patients who tested positive for COVID-19 infection, increased amounts of nasal secretion and prolonged nasal clearance time were observed. They also had higher SNOT-22 scores than those of the negative controls. Although these findings demonstrate that there may be changes in nasal functions in patients positive for COVID-19 infection, new studies are needed to elucidate the nasal effects in detail.
