Of course, the effectiveness of cochlear implantation for congenital sensorineural deafness is undeniable, as it allows deaf children to enter the audible world without being mute and to integrate into normal social life, reducing the burden on families and society. However, what the public does not understand is that the age ratio of patients in China and developed countries is different in the population of cochlear implants. In our country, infants and children are the majority, while in developed countries, adults are the majority. This may be related to the cultural background and mindset of different countries. In our country, the public will pay more attention to children, and children’s problems are more likely to be taken seriously, and it is more acceptable for parents to have a cochlear implant for congenital deafness that causes mute. For adults or the elderly, the first thing to consider when they have a certain degree of hearing loss is their appearance, and secondly, when it comes to hearing aids or cochlear implants, they are always afraid of being told that they are old. In fact, cochlear implantation is suitable for patients of all ages with severe to profound sensorineural deafness in both ears. In adults and the elderly, cochlear implantation is indicated when the diagnosis of severe to profound sensorineural deafness in both ears has been confirmed after the exclusion of occupational or central auditory nerve pathology. When an adult or an elderly person suffers from severe or profound sensorineural deafness in both ears, the patient will not be able to hear the sounds around him or her and will not be able to communicate with others normally, and the patient will be reluctant to communicate with others over time. The harm is self-explanatory. Therefore, I would like to appeal to adults and elderly people not to take their hearing seriously, but to actively choose hearing aids and cochlear implants according to the degree of their hearing loss. When you have severe to profound sensorineural deafness, cochlear implantation is a good choice for you.
