Abstract

Results of this study demonstrated that a new olfactory test, the "Sniffin' Sticks," can be used to distinguish hyposmic patients with chronic sinusitis (n = 63) from control subjects. Dirhinic testing yielded improved olfactory sensitivity compared with monorhinic testing. However, dirhinic results were not significantly different from results obtained for the best nostril.
