The cure rate for sudden total deafness is considered to be half and half internationally, with some sudden deafness having a tendency to heal itself and others requiring active and effective treatment measures, but there are no complete statistics in China. In general, the cure rate for sudden total deafness in China is very small, but most people need to take early treatment measures, and in some cases, even if they take early treatment measures, they may not necessarily achieve a complete cure, and some of them only improve their symptoms significantly, so the cure rate may be relatively low, reaching about 20%-30% at most. Therefore, it is important to actively search for the cause of sudden total deafness, and then take appropriate treatment according to the different causes.
