Hyperbaric oxygen can treat tinnitus and is generally indicated for neurological tinnitus, but is not effective for tinnitus caused by inflammation, etc. Hyperbaric oxygen therapy can improve the oxygen-deficient environment of the inner ear by reaching the inner ear with a higher concentration of oxygen, which is conducive to the recovery of tinnitus. Patients with tinnitus are usually accompanied by hearing loss. Tinnitus can be low-pitched or high-pitched, and is generally divided into acute tinnitus and chronic tinnitus. Treatment recommendations are as follows: 1. Acute tinnitus: In addition to hyperbaric oxygen therapy, hormones such as dexamethasone, and vasodilator drugs such as betahistine hydrochloride are usually required for good treatment. 2. Patients need to avoid noise environment in their life, which has a certain effect on reducing damage to the inner ear.
