ABSTRACT
BACKGROUND AND OBJECTIVES:
The exact diagnosis for olfactory dysfunction plays an indispensable complementary role to the proper management of olfactory dysfunction. But there is no confirmative objective method for olfactory function evaluation. Recently, olfactory evoked potential by jet steam method was introduced as an objective method for the evaluation of olfactory function. The purpose of this study is to evaluate clinical efficacy of olfactory evoked potential. SUBJECTS ANDMETHOD:
Thirty two normal individuals were evaluated with olfactory evoked potential and their olfactory thresholds were within normal range when tested with T&T olfactometry. Odorant, skatole was introduced 1cm apart from the nostril by jet steam pulse. The results were averaged by Neuropack Four Computer.RESULTS:
Twenty-nine individuals had typical positive waves with latency near 0.1ms, but three individuals had no typical positive wave. The threshold of twenty individuals in electro-olfactometry was E1 with E1 recognition or detection threshold in T&T olfactometry. The threshold of other nine individuals in electro-olfactometry was E2 with E1 recognition and detection threshold in T&T olfactometry.CONCLUSION:
Olfactory evoked potential has good correlation with classic T&T olfactometry and could be used as an objective method for the evaluation of olfactory function.
