In September 1973, amidotrizoate (76% Urografin) was injected intravenously in one case of sudden deafness for the test of iodism and significant effects on hearing and tinnitus were observed. On the bases of this experience, intravenous injection of 1-2ml amidotrizoate was tried for the treatment of sudden deafness with obscure etiology. During the past 6 months, six of 20 cases have recovered completely in a few days after institution of this treatment. The rate at which hearing returned in these cases was compared with that in other cases which were treated successfully by the stellatum blockade or others, and it was found that the former was significantly steeper than the later. This new method of treatment was uneffective for the cases with high tone loss or total loss of hearing. The probable effect of amidotrizoate for sudden deafness was discussed.
