Impact of odor exposure time on olfactory parameters
Abstract
Objective: The aim of this study was to assess the impact of odor exposure time on odor threshold, odor identification and discrimination. Methods: Ninety healthy volunteers were randomly divided into three groups: Group 1 underwent an olfactory test with the standard odor exposure time (3–4 sec), Group 2 had an odor exposure time of 8–10 seconds, and Group 3 had 30 seconds. Odor parameters of three groups were compared.
Results: Groups 2 and 3 had significantly better odor identification scores
than Group 1. There were no statistically significant differences between
the three groups in terms of mean odor threshold and discrimination
scores. Males of Group 3 had significantly better odor identification
scores than males of Groups 1 and 2 and females of Groups 2 and 3 had
significantly better odor identification scores than females of Group 1.
Conclusion: The results of the present study showed that longer odor
stimulation led to higher odor identification scores. However, odor
threshold and odor discrimination were independent from the odor
exposure time. The odor exposure time of olfactory screening tests may
be revised according to the gender in accordance with our findings
