The most important cause of deafness is otitis media, because otitis media is likely to lead to the blockage of the Eustachian tube, thus affecting the function of the Eustachian tube, the symptoms of ear stuffiness and deafness. If there is fluid in the tympanic cavity, tube placement or tympanic membrane puncture drainage is needed. If there is no fluid accumulation, you can do nose pinching and cheek puffing or local tympanic membrane massage, while pulling the auricle, maybe some kind of orientation may make the Eustachian tube open, and in severe cases, Eustachian tube blowing and tensioning may be performed, which will help the recovery of hearing. The cause of the disease must be treated. If the disease is caused by bacterial infection, anti-inflammatory drugs such as penicillin or cephalosporin can be taken; if it is caused by viral infection, anti-viral drugs such as Shuanghuanglian Oral Liquid or Shuanghua Tablet can be taken, and Chinese medicines such as Deafness and Tongjiao Pill can be used as supplemental Chinese medicines.
