Abstract
Background and Objectives：KVSS (Korean Version of Snifin Sticks) identification test using 16 odorants familiar to Koreans is used for evaluation of olfactory function. We analyzed the correct-answer rate of the odor identification test among KVS test to validate the reliability of these odorants. Subjects and Method：From April 2004 through August 2006, 720 patients under-went an odor identification test and from these, 441 patients who scored more than 9 were included. The score groups were ：more than 9, 10, 11 and 12 score group. The age groups were divided into 4 groups：0- 19, 20- 39, 40- 59, 60 and more than 60 year-olds. The diferences in the correct-answer rates of the odorant were investigated according to the score groups, age groups and sex were calculated using SPS software. Results：The odorant 6 (lemon), 7 (licorice), 8 (pine resin), and 11 (apple)rant 7 and 11 were significantly lower than other odorants except odorant 6 and 8 in all score groups, in all age groups and both sex (p≤.001). Conclusion：In the odor identification test, odorants 7 and 11 had low reliabililty for evaluation of the olfactory function, maybe due to unfamiliar odorants to Koreans or test pen failure and they had better be changed into more reliable odorants. For that, we need further investigations about KVSS test before widely used. (Korean J Otorhinolaryngol-Head ;50 :1109-13)
