I investigated the effectiveness of the immediate caloric test for acute vertigo cases. I was able to diagnose 21 (29.5%) cases of vestibular neuronitis immediately by performing a caloric test in 71 acute vertigo cases. I confirmed that as an effect of the steroid dosage on vestibular neuritis, the maximum slow phase velocity of the nystagmus significantly improved after the steroid dosage from the second week, and the obstacles to everyday life due to the vertigo using DHI (Dizziness Handicap Inventory) significantly improved from the fourth week. I made the first medical examination within 30 days from the onset and, for vestibular neuronitis cases in which treatment was started, the effect of the steroid treatment was significantly seen in all cases. I diagnosed vestibular neuronitis by performing a caloric test for the acute vertigo cases immediately, and starting treatment promptly was believed to be required.
