Three cases of bilateral Sudden deafness in infants which we had experienced for these 5 years were reported and their specificity and origin were discussed.
1.Despite of the adequate treatment from the onset of the disease, hearing disturbances recurred in two of them and another one became almost deaf after a progressive involvement.Therefore, their prognosis was considered poor.
2.Considering that the cases of the Meniere disease due to the autonomic nervous and circulatory disturbance were very few in the infant, it was assumed that the origin of the sudden deafness of the infant was ascribed not to the autonomic nervous disturbance but to some infection such as virus one.
3.We also considered that the individual disposition would be an important factor for this disease
