[The effect of drug therapy and stellate ganglion block with or without oxygen inhalation on sudden hearing loss].

Forty-one patients suffering from sudden hearing loss were studied by the following method. Twenty patients (group A) were treated with oral administration of prednisolone, intravenous administration of vitamin B and C, furosemide and stellate ganglion block. Another 21 patients (group B) were treated with oral administration of these drugs, stellate ganglion block and oxygen inhalation. Forty six percent of all these patients, 35 percent of group A and 57 percent of group B, regained less than 20 dB of their normal hearing level. The patients who are younger, having shorter duration from first finding of symptoms to starting of therapy and smaller average deficiency of hearing, without dizziness are easy to recover. Oxygen inhalation with drug therapy and stellate ganglion block is a useful treatment for sudden hearing loss.
