Usefulness of word table for the quantitative evaluation of the recognition threshold in children's olfactometry

In the quantitative evaluation of the recognition threshold in smell test, the influences of subjects' age, intelligence, and experience are unavoidable in expressing the nature of smell, especially in children. In order to avoid such individual differences, a word table has been designed in our clinic. In this study, we employed a word table for children's quantitative evaluation of the recognition threshold, and found that T & T olfactometry performed with use of a word table showed a greater reliability compared to the test without use of a word table. The use of a word table for children's olfactometry is also considered to be an easily administered procedure.
