The main purpose of the operation is to insert the electrodes into the cochlear and to place the receiver in the bone behind the ear. The operation lasts 2-3 hours and usually requires 2-3 days hospitalization.
 

After the Operation

About a month after surgery, when the wounds have healed, the patient returns to Shaare Zedek to receive the external part of the implant and to begin the implant matching process. The patient will not hear through the implant until the external components have been adapted and tuned.
This process is called mapping, in which the audiologist programs the speech processor. Each patient is different and so the processor must be individually adapted. These differences occur because the location of the electrodes changes in relation to the functioning nerves and because of each person’s neural sensitivity to the electric current.
Mapping happens frequently ןn the early weeks and months, because it takes time for the ear and the brain to adapt to the new form of auditory stimulation. Once the patient becomes used to the device, there is less need for mapping and we monitor the process perhaps once or twice a year. 
With children, it is important for the rehabilitative speech therapist to work closely with the mapping audiologist to ensure the child attains good hearing functionality.
The patient is also entitled to a number of hearing training sessions with a speech therapist.

 

Results

The benefits of an implant are not identical for every patient. These include revealing and identifying surrounding sounds, improving interpersonal communication and understanding speech without needing visual hints.
Our experience shows that children usually derive great benefit from the implant. Most child implant patients lost their hearing before they acquired speech, language and even listening skills. Studies show that a large percentage of these children are capable of learning to understand speech without the need for lip reading and demonstrate a significant improvement in their language and communication.
Clinical experience proves that the later a person with severe hearing loss has an implant, the harder it will be for him or her to obtain significant auditory data from the implant.
The Administrative Part of the Implant Operation
After completing the suitability evaluation stage, a recommendation will be submitted to the prospective patient.
Once the patient or the family decides to undergo the operation, you must obtain commitment from your health fund (kupat holim) for both the operation and the implant.
After the operation you must present commitment for every mapping and for any other appointment.
At Shaare Zedek we use implants from the three companies currently in Israel: Cochlear, Advanced Bionics and Med-El. The implant is included in the health basket in all of the health funds.
