Diatrizoate meglumine (Hypaque) treatment for sudden hearing loss.

During the 24 month period ending in December 1978, 31 patients with sudden idiopathic sensorineural hearing loss were treated with vasodilators and Hypaque. Fifteen patients met the treatment criteria of being treated within the first month following onset, no vertigo, and the hearing loss was not complete. Twelve patients (80%) had complete return of their hearing. Two patients (13%) had partial return of their hearing, and 1 patient (6%) had no response to treatment. Of the 16 patients treated who did not meet the criteria, 6 patients (38%) had complete return of their hearing. Eight patients (50%) had partial return of their hearing and 2 patients (12%) had no return of their hearing.
