What happens when the sound processor is fitted?

Several months after the operation, the ENT surgeon, specialist nurse or audiologist will check the surgery wound has healed and that new bone has formed around the implanted abutment. This will usually take three to six months depending on the individual child.

When the abutment is secure, the audiologist will then fit the sound processor. The audiologist should provide clear written instructions on:

  • how to use the bone conduction hearing implant (BCHI) system
  • good hygiene of the site where the abutment is implanted
  • how to care for the equipment
  • how to maintain the system.

You should also receive a copy of the manufacturer’s user handbook and safety guidelines.

Your child will be given the most suitable sound processor for their needs. If your local services haven’t already supported a child with a BCHI, then the auditory implant service will provide training and information to local professionals so they know how to look after your child and the equipment when necessary (for example, when your child is at school).

How well the sound processor is working will be measured using a specialist test box, and compared to the manufacturer’s specifications. The result of this test will be recorded and used as a guide to measure how the processor is working in the future. This should be checked at regular intervals (at least every three months). A listening device can be issued to help you check your child’s sound processor at home.
