title: Comparison of clinical tests of olfactory function.
abstract: To assess olfactory function, various measures are used in clinical routine. In this study, the Sniff Magnitude Test (SMT), a test considering the sniff response to an odor, was applied to patients with olfactory dysfunction (n = 49) and to a control group without subjective olfaction disorder (n = 21). For comparison, the validated "Sniffin' Sticks" test battery, a psychophysical olfactory test consisting of tests for phenyl ethyl alcohol odor threshold, odor discrimination, and odor identification was performed. Analyses indicated that the SMT showed significant differences between patients and controls (p = 0.003). Furthermore, results from the SMT and the "Sniffin' Sticks" correlated significantly (p < 0.001). In conclusion, the SMT appears to be a useful addition to the battery of available clinical tests to assess olfactory function.
