Abstract

The Jet Stream Olfactometer (JSO), a newly developed smell stimulus device, is designed to reduce odor contamination that can occur with T & T olfactometry. The detection and recognition thresholds measured by JSO and T & T olfactometry using three odorants are highly correlated. We assessed the clinical usefulness of JSO using five odorants commonly used in standard olfactory examinations in Japan. Subjects were 354 normal and 356 olfactory-disturbed patients. No significant difference in detection or recognition threshold was seen between JSO and T & T olfactometry for either group, indicating that the JSO is effective in olfactory threshold testing and provides an alternative to T & T olfactometry.
