After Implantation

 

Initial Fitting

This visit is typically two hours in length and has the following goals:

  • Fit the sound processor, microphone, headpiece, harness
  • Create a “first-pass” map or program that is comfortable for the child. Additional maps will also be created for the child to try prior to the next clinic visit
  • Counsel family regarding device operation, troubleshooting, equipment care and maintenance
  • Complete Product Registration and Warranty information

To achieve those goals:

  • The session will begin with measurements of the integrity of the internal device (impedances)
  • Depending on the child’s age and previous hearing experience, subjective or objective measurements will be used to create the maps
    • If Subjective Measurements are possible, individual channels will be stimulated until the child reacts or otherwise indicates that he or she has “heard” something
    • If Objective Measurements are necessary, the implant software is used to measure the auditory nerve’s response to stimulation. The child need not actively participate in this process.
  • Once the processor has been programmed and as the child becomes accustomed to and accepting of wearing the device, attention will turn to the caregivers and imparting knowledge regarding the use, care and maintenance of the device

Follow Up Appointments

  • Because of the rapid adaptation of the auditory system, numerous mapping changes are necessary in the first year of cochlear implant use. For this reason, we have established the following schedule after surgery.
  • Initial fitting (3-4 weeks after surgery)
  • From Initial Fitting:
    • 2 weeks
    • 5 weeks
    • 9 weeks
    • 3 months
    • 6 months
    • 9 months
    • 1 year
  • Children are then seen at six month intervals until they are school age and then they are seen once per year
  • Additional appointments can be scheduled as needed by parents

Auditory, speech, and language therapy are important pieces of the habilitation process. CASTLE and CCCDP staff can help make certain that your child is getting the services he or she needs.
