There is no age limit for cochlear implants for people who develop deafness in adulthood. Because cochlear implants are an effective means of restoring hearing and language is normal in people who develop deafness in adulthood, cochlear implants restore hearing and soon they can communicate normally without the need for language training and with excellent results. The left cochlear implant surgery is very suitable for elderly deafness. The cochlear implant started out to be designed for these people with acquired deafness, because people with acquired deafness have speech function, and after the cochlear implant surgery there is no need for speech training, and it can be used directly. In foreign countries, 60% of cochlear implants are for the elderly, while in China, 90% are for children and less than 10% are for the elderly. This has to do with our national conditions and cultural traditions. Parents of children who are deaf are willing to pay for cochlear implants to restore their hearing, but when the elderly are deaf, the desire of their children to pay is not so strong, and the elderly themselves are not willing to let their children pay for the more expensive medical expenses. However, as people’s standard of living improves and more people pursue quality of life, more and more elderly people will have cochlear implants.
