Sudden deafness belongs to a kind of sudden onset of unexplained sensorineural deafness, and the clinic mainly adopts general treatment and medication to promote hearing recovery. However, it is not certain whether the hearing can be restored to normal. 1. General treatment: patients need to be hospitalized as soon as possible, and at the same time, bed rest, restriction of water, salt and other intake. 2. Drug treatment: (1) Nutritional nerve drugs: It is necessary to treat the disease in the early stage with the drugs that nourish the nerves, such as methylcobalamin, neurotrophic factor, etc., which can play a role in improving the microcirculation of the inner ear and nourishing the nerves. (2) Glucocorticoid drugs: such as commonly used methylprednisolone, dexamethasone, etc., can play an anti-inflammatory, decongestive role, suitable for the treatment of various types of sudden deafness. (3) Fibrinogen-lowering drugs: such as the commonly used bacitracin, etc., can play a role in lowering fibrinogen, thus improving the microcirculation of the inner ear. (4) Low molecular dextrose: it can play a role in lowering blood pressure viscosity and reducing red blood cell coagulation, thus improving capillary circulation. 3.Others: (1) Hyperbaric oxygen therapy: it can increase the partial pressure of oxygen, which can increase the amount of physically dissolved oxygen in plasma as well as the rate of blood oxygen diffusion. Thus, the phenomenon of tissue hypoxia is rapidly corrected; secondly, in the case of increased partial pressure of oxygen, the heart rate slows down and the cerebral blood vessels contract. However, due to the increase in blood oxygen content, tissue oxygenation is still increased, while vasoconstriction can improve or prevent the inner ear tissue edema and hemorrhage and other phenomena. (2) Microwave physiotherapy: It can activate blood circulation and improve microcirculation of the inner ear, so it can play a certain therapeutic effect. Specific treatment methods should be combined with the patient’s condition and used reasonably under the doctor’s guidance. Most of the conditions can be relieved if patients are treated in time.
