• More than 500 employees around the globe
What you will learn today:
• How the ear works
• How to interpret the audiogram
• Cochlear Implant Candidacy
• Treatment Options for Hearing Loss
• Management of a child with a cochlear implant
The ear consists of four main parts:
Brain
Inner Ear
Outer Ear
Auditory
Nerve
Middle Ear
The Outer and Middle Ear
Ear Drum
Bones of the
Middle Ear
The Inner Ear
Brain
Cochlea
Auditory Nerve
Hearing Loss
Brain
Without functioning
sensory cells in the
cochlea, sound
information cannot
reach the brain for
processing.

Audiological Evaluation
• Determine the type and degree of hearing loss
• Air & bone conduction thresholds for each ear
• ABR & OAEs
• Assess the child’s current amplification system
• Aided sound field testing
• Aided speech perception testing
• Counseling
• Address realistic expectations
• Device selection
• Post-operative follow-up
Medical Evaluation

What do parents want for their child?
• …to be able to hear like everyone
else does
• …to fit in
• …to realize their potential
• …to be successful listening in
today’s world
How Does a Cochlear Implant Work?
•
Sound waves enter through the microphone.
•
The sound processor converts the sound into a
distinctive digital code.
•
The electrically coded signal is transmitted
across the skin through the headpiece to the
internal portion of the device.
•
The internal device delivers the sound to the
electrodes.
•
The electrodes stimulate the hearing nerve.
•
The hearing nerve sends the signal to the brain
for processing.

Summary
•
Cochlear implants are an effective treatment for severe to
profound sensorineural hearing loss.
•
A multi-disciplinary approach is necessary when determining
cochlear implant candidacy in children.
•
Post-operative management of a child with a cochlear
implant consists of programming of the sound processor and
intensive rehabilitation.
•
Parent commitment and school support are necessary
components to ensure a child’s success with a cochlear
implant.
