Taste fibers reach the facial nerve from the anterior two-thirds of the tongue via the chorda tympani verve, which may join it at a variable point from the middle of the vertical segment to a level external to the temporal bone. Clinical taste testing with solutions of salt, sugar, acid and quinine is time-consuming and difficult to quantitate. The only quantitative measurement of the function of taste is by the electrical method. Krarup described electrogustometry as a substitute and an improvement over other methods. The test is based on the metallic taste sensation occurring when a positive current is applied to the tongue. Krarup noted that it was not the absolute sensitivity, but a difference of sensitivity of one side of the tongue from the other, which signifies an abnormality. He pointed out the importance of a unilateral decrease in sensitivity in taste in the diagnosis of facial nerve palsy and cerebellopontine angle lesions. Authors measured and analyzed electrogustometry thresholds of 120 patients without ear, oral diseases of neural lesions by using of the Life-Tech Model 4000 Electrogustometer. The results were as follows ; 1) The gustatory thresholds were highest under 10 years of age group and decreased at second, third and forth decades of age group and rised with rise in age after fifth decade of age. 2) There are significant differences of the gustatory thresholds between the sexes of under 10 years of age group, but no significant differences of the gustatory thresholds between the sexes of other age groups. 3) The mean and 2 standard deviation of a threshold difference between the right and left sides of the tongue of the all age & sex groups reveal 5.90±15.90 UA(p=0.23, by sex, p=0.16, by age). There was statistically no interaction between age and sex.
