What about using sniffin’ sticks 12 items test to screen post-COVID-19 olfactory disorders?

BACKGROUND: Post-COVID-19 Olfactory impairment has a negative impact on quality of life. The Sniffin Sticks test 12 items (SST-12) can be used in quick olfactory disorders screening. Its evaluation in a post-covid-19 situation was the main objective of this work. METHODS: All patient impaired with a post-COVID olfactory loss were included while consulting to the ENT department. The clinical examination included an olfaction recovery self-assessment (VAS), a nasofibroscopy, a quality of life (QoL) assessment, the complete Sniffin’ Sticks Test (SST), and the SST-12. RESULTS: Among the 54 patients included, 92% (n = 50) were correctly screened as olfactory impaired by SST-12. We report excellent correlations between SST-12 and SST (rho ((52)) = 0.98, p < 0.001), QoL(rho((52)) = 0.33 p = 0.016), or VAS (rho((52)) = 0.49, p < 0.001) assessments. CONCLUSIONS: SST-12 is a quick and reliable tool to screen large-scale population of post-COVID-19 olfactory impaired patients and could be used in a general daily clinical practice.
