Indirect deafness is clinically called sudden deafness. There is no exact cause of sudden deafness, but it is mainly related to the patient’s anxiety, poor rest, staying up late, or being infected by a virus, and genetic factors. In addition to the symptoms of intermittent hearing loss, patients may also experience tinnitus, and in severe cases, they may also experience vertigo and a feeling of stuffiness in the ears, which can cause great inconvenience in their lives. In terms of treatment, the clinical application is to improve circulation and nerve nourishing drugs, such as Ginkgo biloba extract tablets, nicergoline tablets, methylcobalamin dispersible tablets, coenzyme A, cytophosphatidylcholine sodium capsules, etc. Patients can selectively apply them, and can also assist in acupuncture, or hyperbaric oxygen to treat. If necessary, patients can consider hospitalization to improve circulation and nerve nutrition by infusion. After active treatment, the patient’s condition should improve.
