The bithermal caloric test was used in the examination of 354 patients with inner ear lesions. The authors caluculated DP% according to Jongkees' formula using the maximum slow phase velocity of the electro-nystagmogram. DP was found in 25% (87/354) of the patients among all the age groups and various inner ear diseases: Meniere disease, sudden deafness, syphilis of the labyrinth, positional vertigo, sensorineural hearing loss, etc. Sensorineural hearing loss was found in 90% (78/87), tinnitus was a complaint in 79% (69/87), repeated vertiginous attacks in 43% (37/87), and fluctuating hearing loss in 26% (23/87).
