The possible causes of severe tinnitus are hearing damage, drug ototoxicity, vasogenic tinnitus, depression, otitis externa, and acoustic neuroma. Depending on the disease, it can be treated by improving hearing, discontinuing medication, improving circulation, psychotherapy, controlling infections, and removing tumors, respectively. There are many factors that cause severe tinnitus. For patients with hearing loss, hearing can be improved by wearing hearing aids, cochlear implants, etc. to mask the tinnitus; if the tinnitus is caused by drug ototoxicity, the drugs should be discontinued to prevent the disease from progressing. If the tinnitus is of vascular origin, painful surgery can be performed to cover or block the responsible blood vessels; if the patient is depressed and insomniac, the tinnitus symptoms can be alleviated through psychotherapy and correction of sleep disorders. If the tinnitus is caused by otitis externa and secretory otitis media, the infection should be controlled under the guidance of a doctor; if the tinnitus is caused by cerumen (earwax) embolism, the doctor can remove the cerumen to alleviate the symptoms; or it may be caused by an acoustic neuroma, which can be surgically removed under the guidance of a doctor. If tinnitus is persistent or recurring, the patient should consult a doctor in time to find out the cause of the disease and standardize the medication and treatment under the doctor’s guidance. At the same time, tinnitus patients should pay attention to stay away from factors that cause tinnitus or hearing damage in daily life, including staying away from noise.
