Clinical Observations on the Sudden Deafness

We have studied 23 cases of subden deafness, and some considerations are as follows. There were 12 males, and 11 females in our cases; 21 cases were affected in our side, and only 2 cases in both sides. The audiogram at the first visit showed that severe hearing loss type were the most, flat type the second, and hightone loss type the third. There revealed more flat type and hightone loss type as the day of first visit were delayed. Therefore, we found out that the sudden deafness had a tendency of spontaneous recovery to a certain degree. As to the prognosis, 8 cases showed improvement, but 11 cases showed no changes at all. The most effective treatment so far found was using steroids combined with ATP, Vit. B, and vasodilators.
