According to current literature, hearing cells cannot be regenerated. Hearing cells mainly refer to the inner ear hair cells, which play an important role in maintaining human hearing, and the most important feature of these cells is that once necrosis occurs, it will be irreversible. There are only a limited number of auditory hair cells in the human body, and damage and necrosis of some of them will lead to irreversible hearing loss. Clinically, if a patient has a significant hearing loss and a hearing test shows that he or she is suffering from high frequency neurogenic deafness, it is recommended that the patient actively go to an ENT clinic for a comprehensive symptomatic treatment of nerve nutrition, vasodilatation, hormone and other medications, and try to see if the damage to the inner ear hair cells can be restored within a short period of time through medication. If the treatment is ineffective or if the onset of the disease is too prolonged for more than three months, the hearing cell damage and necrosis will be irreversible. For patients with hearing loss due to necrosis of most of the hearing cells, hearing loss can be relieved by hearing aids or cochlear implants.
