  1. CochlearImplant & Bone Anchored Hearing Aid How the hearing sense works? The Cochlearimplant, CI. Who is a candidate for cochlearimplant? Manufacturersof CI. Compatibilitybetween Comfort Digisystem and the availablecochlearimplantsin the market. Bone Anchored Hearing Aid The typical BAHA user. Manufacturersof BAHA. Compatibilitybetween Comfort Digisystem and the BAHA

  2. The human Hearing sense The outer ear picks up the sound vibrations The Sound vibrations are directed to the middle ear by the ear channel

  3. The human Hearing sense Ossicular Chain The Ear drum sets the Ossicular chain in motion The Ossicular chain in its turn sets the Perilymph (Fluid in the cochlear) in the cochlear in motion

  4. The human Hearing sense The Mechanical vibrations are converted to the electrical pulses by the hair cells The electrical pulses are sent to the auditory cortex by the auditory nerves

  5. CochlearImplant Some facts about the Cochlear Implant: Around 1790 Alessandro Volta experimentally discovered that electrical stimulation in the auditory system can create a perception of sound. “ It is like a thick boiling soup“, He said. André Djournoperforms the first cochlear implantation in France, Dr. Michelson's patents and device are thought as the first cochlear implants. Alessandro Volta André Djourno

  6. CochlearImplant • A cochlear implant consists of two parts: • The sound processor • The implant A flexible electrode array is inserted into the entire cochlear

  7. CochlearImplant The sound vibrations are converted to electrical signals and transmitted through the skin into the implant via the coil. The implant creates electrical pulses from the received signals and sends them to Auditory Cortex via Cochlear and auditory nerves.

  8. Cochlear Implant Brief overview

  9. Who is a CI Candidate? For young children: 12 months to 2 years Have profound sensorineural hearing loss (nerve deafness). Receive limited benefit from hearing aids. Children: 2 to 17 years Have severe-to-profound sensorineural hearing loss (nerve deafness). Receive limited benefit from hearing aids. Adults: 18 year and overHave moderate-to-profound sensorineural hearing loss (nerve deafness). Receive limited benefit from hearing aids. Score 50 percent or less on speech recognition tests in the ear to be implanted and 60 percent or less in the non-implanted ear when using hearing aids.
