Abstract
The treatment and prognosis of sudden deafness were discussed. Twenty-six cases were analysed from the following clinical standpoints; age, sex, cause of onset, major symptoms, audiogram types, methods of treatment, recovery forms and prognosis. Factors concerning prognosis of sudden deafness were also discussed. The importance of early treatment was emphasized for prognosis of hearing. The improvement of hearing was observed in sixteen cases of sudden deafness of which treatment was started from the onset. However, the improvement of hearing was observed in only one ear in ten cases of which treatment was started more than fifteen days after the onset.
In various therapeutic methods, the effect of low molecular dextran and steroid were most remarkable. Follow up study of audiogram types was useful to assess the clinical picture and prognosis of this disease. The patient with flat type of audiogram showed good prognosis.
