After aging, many elderly people developed back of the ears, which is called senile deafness. Some merchants promote drugs through the mentality of the elderly eager to treat the disease, claiming that taking medicine and physiotherapy can cure the back of the ear, reminding elderly friends not to be deceived.

　　Understanding senile deafness, let’s take a look at the principles of hearing. The ear is composed of three parts: outer ear, middle ear and inner ear. The outer ear includes the auricle or external auditory canal, the middle ear includes the tympanic membrane, tympanic cavity, mastoid and their ossicular chains, and the inner ear includes the semicircular canal, vestibule and cochlea, of which the cochlea is our auditory receptor. When the sound is emitted, the sound is collected by the outer ear and the external auditory canal and transmitted to the tympanic membrane. The tympanic membrane vibrates, driving the ossicular chain to vibrate, which connects the inner ear, transmits the sound vibration to the inner ear, and the cochlea converts it into bioelectricity The auditory nerve is transmitted to the auditory center, which produces hearing. Senile deafness is the result of multiple factors that accumulate over time and damage the hearing system.

　　 The most basic reason is the aging or problems of the cochlea, auditory nerves and auditory center of the elderly. The cells that play a key role in these parts cannot be regenerated. Once damaged, the related functions will be affected together. Under the current medical conditions, senile deafness cannot be cured by taking medicine and physical therapy. Moreover, noise, cardiovascular disease, metabolic diseases (such as hyperlipidemia, diabetes), the use of ototoxic drugs, kidney disease, genetic factors and smoking are also risk factors for senile deafness. If you have the above problems, the elderly should pay special attention to the health of the ears and beware of senile deafness.

　　 Senile deafness cannot be reversed, so the elderly must pay attention to prevention and avoid damage to hearing organs, such as less exposure to strong noise environment, control blood pressure, blood lipids, blood sugar, and avoid the use of ototoxic drugs. If the elderly are in the early stage of senile deafness, they can go to the hospital for medical treatment to delay the aging of hearing organs. For patients with severe hearing loss that affect their lives, they can wear hearing aids in a timely manner. They can also conduct comprehensive examinations and doctor recommendations, implant cochlear implants, use bone anchored hearing aids, or adopt other hearing aid technologies and rehabilitation treatments. Senile deafness is not terrible, correct treatment can improve hearing and communication skills, and must not blindly listen to advertising. In the event of hearing loss, seek medical attention as soon as possible.
