Background and Objectives: Recently, the prevalence of olfactory dysfunction has increased with pollution and populationadequate. Treatment by olfactory training has been suggested as an alternative method, but there is no protocol for olfactorytraining with odorants familiar to Koreans. Also, no studies have analyzed the effects of individual preference in terms of personalizedmedicine. This study compared the effectiveness of olfactory training according to patient odor preference.
Materials and Method: The prospective study was performed in patients with olfactory dysfunction and used 8 total odorants. After a survey of preference for the odorants, patients were divided into two groups, one group performed olfactory trainingwith 3 preferred odorants, whereas the other group performed training with odorants they did not prefer. Also, the effects ofolfactory training in the two groups were compared by KVSS threshold, discrimination, identification score, and subjective VASscore of olfaction. Olfactory testing was performed before and after training for 4 and 12 weeks.
Results: There was no demographic difference between the two groups. After olfactory training, the preference group showedstatistically significant improvement in threshold, identification, TDI score, and VAS score. Conversely, there was no significantchange of olfactory function in the non-preference group.
Conclusion: Thus, we conclude that odorants of olfactory training should be applied depending on cultural preferences, andthat the preferred odorants of each individual patient will have a greater therapeutic effect on olfactory dysfunction compared tonon-preferred odorants.
