ABSTRACT
The odor stick identification test (OSIT) is a new test of olfactory function recently developed for Japanese people. The purpose of the present study was to evaluate this test in relation to T&T olfactometry and the cross-cultural smell identification test (CC-SIT) by applying to 110 Japanese patients with olfactory disturbance. The averaged recognition thresholds for five odorants in T&T olfactometry, the number of correct answers in the CC-SIT and the rates of identification of 13 odorants in the OSIT were compared. The visual analogue scale (VAS) was also used to evaluate symptoms. The rate of identification of OSIT showed high and significant correlation coefficients with the averaged recognition thresholds of T&T olfactometry (-0.766, P < 0.001), with the number of correct answers in CC-SIT (0.754, P < 0.001) and with the VAS score (0.591, P < 0.001). In addition, on the identification performance measured by OSIT, we found significant differences between all pairs of four degrees of olfactory dysfunction except for one pair. Thus, we conclude that OSIT is useful for evaluating olfactory dysfunction in Japanese people.
