What is MAPping?

MAPping is the process by which the audiologist determines the amount of electrical stimulation each electrode delivers to the auditory nerve so that the child can respond. MAPs are adjusted over time. Sometimes the MAPing process takes several appointments to ensure correct settings.  It is important to see the audiologist as recommended to make sure your child has the most appropriate MAP.

What happens during the initial stimulation or hook up of the cochlear implant?

During the initial stimulation, which occurs a few weeks after surgery, the audiologist will create an initial MAP for the child and discuss in detail how the external equipment works. Children react very differently during this initial stimulation - some cry, some smile and some show little reaction. The audiologist will make sure your child is comfortable when he/she leaves the office.

How often will my child have to see the audiologist once they receive a cochlear implant?

There is not a single schedule for MAPping that every child must follow. During the first year after receiving the implant, children are seen frequently. Generally, children are seen the day of the initial stimulation, two weeks post initial stimulation, one month post stimulation, three months post initial stimulation, six months post stimulation, 12 months post initial stimulation, 18 months post initial stimulation, two years post initial stimulation, and annually thereafter. Of course, some children may need to be seen more often.

What kind of speech-language therapy does my child need?

The individual speech-language therapy needs of children with cochlear implants are specific to each child.  However, in general, children need weekly individual therapy sessions that emphasize listening with a cochlear implant and improving their communication skills. Please discuss your child’s specific needs with our speech-language pathologists.
