- 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.
