There are many causes of tinnitus: first, you need to go to the hospital to check the condition of the external ear canal and the eardrum to rule out whether the tinnitus is caused by earwax or cerumen embolism in the external ear canal, which is close to the eardrum. If you find earwax or cerumen embolism, you need to soak it with sesame oil and then go to the hospital to take it out. Don’t take it out at home by yourself, as it will easily cause otitis externa and tympanic membrane perforation. Secondly, the middle ear cavity is not accessible to the eustachian tube due to acute inflammatory infections, thus producing tinnitus. During the examination, the tympanic membrane can be seen to be flat with gas and liquid, and bubbles can be formed in the tympanic membrane when the nose is squeezed and puffed with force. In the treatment, middle ear cavity effusion needs to be punctured and drained, while oral anti-inflammatory drugs and mucosal pro-discharge agents can be gradually cured. Thirdly, due to prolonged late night and poor rest, the ear nerve becomes ischemic, edematous and spasmodic, causing neurogenic tinnitus. In this case, patients usually also have hearing loss, and need to check electrical audiometry and acoustic impedance to confirm the diagnosis of neurogenic tinnitus, which requires symptomatic nerve nutrition treatment, and can be treated with oral jinado and methylcobalamin tablets, as well as with acupuncture or hyperbaric chamber.
