Results of cochlear implant surgery vary from person to person. Factors that can affect the outcomes of cochlear implantation include the age when hearing was lost, and the length of time between hearing loss and the cochlear implant surgery.
For children, the best results generally occur with getting a cochlear implant at a young age.
For adults, the best results are generally associated with a shorter period of profound hearing loss before cochlear implantation. Adults with little or no experience with sound tend to benefit less from cochlear implants.
Some predicted outcomes may include:
. Clearer hearing. Many people who meet the hearing criteria for cochlear implantation may eventually get clearer hearing with using the device.
. Improved tinnitus. Although ear noise (tinnitus) isn't a primary reason to receive a cochlear implant, the cochlear implant may partially suppress or improve the severity of tinnitus during use. It can rarely worsen tinnitus severity.
