The number of studies examining the symptoms of the otolaryngology system and organs in COVID-19 patients is limited. The purpose of this study is to show whether COVID-19 infections cause any changes in nasal physiology in adult patients by measuring the mucociliary clearance (MCC) time with the saccharin test.

Methods:

One hundred one patients with laboratory-confirmed COVID-19 infection (group 1, n= 42 smokers and group 2, n= 59 nonsmokers) and 87 individuals without COVID-19 infection as the control group (group 3, n= 33 smokers and group 4, n= 54 nonsmokers) were included in the study. A saccharin test was used to evaluate the nasal MCC time.

Results:

Mucociliary clearance test averages of the groups were determined as …
