Choosing a Cochlear Implant
Why cochlear implantation?
To date, cochlear implantation is the most effective method for the rehabilitation of deaf people. After the operation, patients begin to hear and understand human speech. But the decision to conduct it is always also the choice of that cochlear implant, with which a person later has to live his entire life, and therefore it plays a huge role.
Compare cochlear implants
Several manufacturers of cochlear implantation systems are on the world market and, undoubtedly, there are plenty to choose from. Correctly selected cochlear implant is a guarantee of the future good perception of the child or adult sounds of the surrounding world and music, the ability to easily go through additional medical examinations (MRI), as well as easier and effective training of the baby speech. In addition, the size of the implant, as well as the reliability and convenience of wearing the speech processor, are of no small importance for small patients.

Cochlear implantation in children and adults: features of the procedure
The only effective method of rehabilitation of children with complete deafness.
- The system consists of two parts: an internal (cochlear implant) and an external (speech processor).
- During the operation, a system of electrodes is built into the patient's inner ear, which, with the help of electrical stimulation of the remaining fibers of the auditory nerve, helps to perceive sound information.
- This is the most effective method for the rehabilitation of deaf children: with a cochlear implant they can hear and understand human speech.
- The system works as follows: the signal is delivered directly to the auditory nerve, bypassing the non-functioning parts of the ear, whereas conventional hearing aids simply amplify the sound.
- After cochlear implantation, a systematic adjustment of the speech processor in children and rehabilitation is necessary.
