Cochlear implants are “artificial organs” that are used for life. The surgical implant portion of the cochlear implant is designed for lifetime use, with a design life of 70 years, and technology will evolve even more in the future. Therefore, it is generally accepted that children may have to upgrade and replace their cochlear implants 1-2 times in their lifetime, but if the implant is not damaged by external factors such as severe trauma, it can generally be used for a long time. The in vitro portion of the cochlear implant is comparable to other commonly used electronic devices and is generally designed to last 20-30 years. It can also be used for a long time if it is properly protected and maintained, and manufacturers of the in vitro portion will provide long-term overhaul and repair services and paid replacement.
