A tool for the psychophysical assessment of olfactory dysfunction in patients with COVID-19.

ABSTRACT: Numerous studies have reported that patients with coronavirus disease 2019 (COVID-19) experience alterations in the sense of smell. Therefore, there is an increased need for a psychophysical evaluation tool for olfactory dysfunction in patients with COVID-19 without increasing the risk of virus spread. We applied a single-use sniffing-bead system, which consisted of small beads and a disposable plastic handpiece, to patients with COVID-19 presenting with olfactory dysfunction. The bead sets contained eight concentrations of 2-phenylethyl alcohol (PEA), which has been used in olfactory function tests for many years, and the lowest concentration at which the participant detected the PEA odor was recorded as the PEA threshold. The test was easily administered at the clinic during the consulta
