When hearing aids aren’t enough, cochlear implants can open a new world of sound and connection. These tiny devices are implanted through surgery and are meant for individuals who have moderate to severe hearing impairment and continue to have trouble comprehending speech despite using hearing aids. Who can potentially benefit from a cochlear implant, and what criteria establish whether someone is a suitable recipient for this technology? Let’s examine it more thoroughly!
Cochlear implants – what are they?
Different from hearing aids, which merely amplify sound, cochlear implants work by directly stimulating the auditory nerve, bypassing the damaged areas of the inner ear. This helps the brain to receive and interpret sound signals more clearly.
Cochlear implants consist of:
- An external sound processor, which is positioned behind the ear
- During a surgical procedure, an electrode array and internal receiver are placed underneath the skin and inside the cochlea
They work in unison to improve hearing for individuals who receive minimal or no assistance from conventional hearing aids
Basic candidacy guidelines
Both kids and adults are approved by the FDA to use cochlear implants. Ideal candidates generally meet the following requirements:
- Moderate to severe hearing loss in both ears
- Hearing aids are giving modest help, especially in improving speech comprehension
- Enthusiasm and reasonable anticipations regarding the results of implants
- Commitment to follow-up care, including programming (called “mapping”) and auditory rehabilitation
- Children as young as 9 months old, with extensive hearing loss in both ears
- Youngsters aged 2 and older with substantial to extreme hearing loss, who do not experience substantial improvement with conventional hearing aids
- Children with progressive hearing loss, where hearing continues to decline over time
- Have extreme hearing loss in one or both ears
- Struggle to make out words and conversations, despite using advanced hearing devices
- Possess a deep desire to express yourself and remain linked to others
- Committed to participating in consistent auditory rehabilitation and device adjustments
- A full hearing exam with and without hearing aids
- Testing for speech recognition
- Trying out a hearing aid, if you haven’t already
- Using medical imaging like CT scans or MRIs to analyze the structure of the inner ear
- Consultation with an ENT specialist or cochlear implant surgeon
- Examining objectives, expected outcomes, and information exchange requirements
