A cochlear implant cannot be matched only once. If the in-vitro unit is damaged, etc., you should go to the hospital in time to have it matched.
The cochlear implant is a special acoustic-electrical converter electronic device, which is extremely suitable for patients with severe or profound sensorineural deafness in both ears, or those who wear hearing aids with mediocre results.
Cochlear implants are semi-implantable electronic devices with a life expectancy of about 70 years, while in-vitro devices last about 10 years. If the in-vitro device is lost or malfunctions, it can be replaced at any time, and it is not a one-time-only match.
After wearing the cochlear implant should pay attention to self-protection, prevent the cochlear implant from impact, avoid going to places with large magnetic fields, pay attention to rest, keep a good mood.
