Can the hearing loss of a human ear heal on its own?

    Generally speaking, if it is neurogenic deafness, it cannot be cured. If it is caused by ear canal deformity, it can be treated by surgery.

     The hair cells and nerve cells that give us hearing are only produced during embryonic development.Once damaged or lost, it cannot be regenerated.The bending or deflection of the cilia on the top of hair cells is a special form of response to acoustic vibration stimulation, which converts mechanical energy into bioelectricity, which causes the start of hair cell excitement.Hair cell damage is one of the main reasons for sensorineural hearing loss.When hair cells are damaged by external stimuli, they cannot spontaneously produce new hair cells, which makes the human ear unable to consciously repairHearing loss.

      When we infer whether the congenital blind or the congenital hearing impaired have a higher standard of living in adulthood, most people wishfully think that the hearing impaired will be better.

      However, a professional survey conducted by the North American Federation of Hearing Impaired People shows that the employment opportunities and physical health of congenital blind people in adulthood are much higher than those of congenital hearing impaired people.

      Because the amount of information obtained by humans through “listening” is far greater than “seeing.”Today, the elderly in China finally believe that hearing impairment is far more troublesome than teeth and eye problems. Hearing problems have become the main reason for their decline in living standards and physical and psychological problems.
So they will ask: “Is it possible for my hearing problem to get better?” Parents of hearing-impaired children will also ask: “Is it possible for my child’s hearing to get better?” How does the audiologist answer?How to deal with these people who long for miracles?Why can’t the human ear automatically repair hearing loss like heal wounds?

     What methods can be used to solve irreversible hearing loss?

1 The goal that can only be achieved after decades of healing damaged hair cells. Researchers at Washington University School of Medicine in St. Louis tried to use growth factors to culture hair cells in vitro, hoping to restore hearing through this method, but this work will take ten years Substantial progress will take longer.Dr. Rafay Holmer, Director of Biomedical Research at the Royal National Institute for the Deaf, said: “We currently have no treatment to restore permanent hearing loss.”

2. Match as soon as possible Hearing aid The method of effective acoustic intervention for culturing hair cells in vitro has not been clinically verified. At present, wearing hearing aids is an effective solution for sensorineural hearing loss.When a patient with hearing loss is diagnosed with sensorineural hearing loss, wear it as soon as possible Hearing aid , To prevent the brain from being uncomfortable with the language for a long time without contact with sound, causing hearing loss to gradually increase and affecting communication.The growth and development process of mammals is different from that of non-mammalian animals. The hair cells in the inner ear cannot repair themselves, resulting in irreversible hearing loss.
