Hyperbaric oxygen has some effect in treating tinnitus, but it is not used much in modern medicine anymore. The principle of treatment is to relieve the patient’s tinnitus symptoms by increasing the oxygen content in the cells. However, if the patient has hypertension, heart disease, etc., hyperbaric oxygen should not be used as it may aggravate the patient’s condition or even cause life-threatening effects. Tinnitus is mainly caused by nerve damage, and it has a lot to do with poor rest and excessive mental stress of the patient. Treatment is recommended to use nerve-nourishing drugs, ginkgo biloba and methylcobalamin tablets are more effective.
