Studies on Amidotrizoate Therapy in Sudden Deafness (1978-1987)

The therapeutic effects of amidotrizoate in 47 sudden deafness patients from 1978 to 1987 were studied. The therapeutic results were investigated in terms of each of four variables: time from onset, degree of hearing loss, type of audiogram, and vertigo. Results showed that patients who had no vertigo, and were treated within 1 week of onset had satisfactory results. The degree of hearing loss did not influence recovery, although all those with total loss type according to audiogram remained unchanged. Twenty-four of 34 cases (71%) treated within 2 weeks showed either complete or marked recovery; this proportion was not much different from the results in our previous investigations.
