Hyperbaric oxygen treatment for tinnitus is effective for patients who present within 3 months. The principle of treatment is to increase the oxygen content in the cells of diseased tissues and relieve the patient’s tinnitus symptoms. Tinnitus is mainly caused by nerve damage, mostly due to overexertion and overstress. The earlier hyperbaric oxygen treatment is given, the better the effect will be, and the treatment of tinnitus with onset within 2 weeks is most effective. At the same time, we should remove the cause, add nerve-nourishing drugs, such as methylcobalamin tablets, promptly treat internal infections and other accompanying diseases, follow a suitable diet and living habits, and maintain a calm mood. If appropriate, use Chinese herbal medicines and proprietary Chinese medicines with anti-inflammatory, blood activating, improving metabolism and promoting restoration effects, such as clearing and dispelling poison pills, Gonglao de-fire capsules and liver sparing and benefitting capsules, Pu Di Lan anti-inflammatory tablets, compound Xuanju capsules, Yan Ke Ning tablets and Astragalus capsules, and change the treatment combination once every half month to better improve the efficacy.
