From Switch-On to Classroom: Rehabilitation and Auditory-Verbal Therapy

The internal device is designed to last a lifetime and does not normally require replacement, barring a major accident. The external processor is upgradeable and generally lasts 5 to 7 years, and patients tend to upgrade whenever a company introduces new technology, such as AI-based features.

Yes, and adult implantation is increasingly common. Someone with progressive hearing loss who already developed language accepts a cochlear implant beautifully, with no contraindication. If a person was born deaf and is now 40, an implant is still possible, but the chance of developing meaningful speech is questionable, unlike someone who lost hearing after already learning to speak.

The definition of success changes with age. Parents of a 2 or 3-year-old want the child to talk, and that is achievable up to about four and a half or five years of age. A 20-year-old implanted for the first time will mainly gain sound awareness, enough to notice a car horn on the road, rather than clear speech. A 10-year-old sits in between and may or may not develop good language. The exception is anyone who lost hearing after already developing speech, for example after an infection: they hear very well with an implant regardless of age.

The first option is always a hearing aid. If it provides adequate, meaningful hearing, meaning the person can discriminate between words rather than just hear noise, that remains the treatment. Presbycusis, age-related hearing loss common in people 80 to 85 years old with no prior history, is a typical cause. If hearing aids only deliver noise without clarity, a cochlear implant is an option at any age.

Absolutely. Chronic myeloid leukemia and even chronic kidney disease are not contraindications, because CML is an indolent, slow-moving disease. As long as the patient is medically stable and vaccinated beforehand, implantation can significantly improve their social interaction and quality of life.

The external processor is switched on roughly one week after surgery. Hearing sound at that point is only the beginning, since the brain still has to learn what to do with it.

A defined sequence of detection, discrimination, identification and comprehension, which typically takes two to three years of intensive rehabilitation to move through.

It is the primary rehabilitation method used after implantation, functioning as much as a parent-coaching program as a child's therapy. Parents are trained to build a listening and language-rich environment at home, not just to bring the child to sessions.

The device has to be worn during every waking hour, without exception, and the home has to function as a consistently language-rich environment.

Assistive listening technology that keeps the child at the front of what is being taught, along with peer buddy systems and regular check-ins from teachers and therapists, so the child does not become socially isolated while the technical side of hearing is addressed.
