Sudden deafness is diagnosed when the above clinical manifestations are present. The earlier the patient is treated, the better the result. Inpatient treatment has several advantages: 1. If the patient cannot be hospitalized for special reasons, he or she must be treated strictly according to the standard outpatient treatment according to the doctor’s orders in order to receive the treatment effect.
