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
Outer Ear
Middle Ear
Inner Ear
Auditory Nerve
Brain
The ear consists of four main parts:
Ear Drum
Bones of the Middle Ear
The Outer and Middle Ear
Cochlea
Auditory Nerve
Brain
The Inner Ear
Without functioning sensory cells in the cochlea, sound information cannot reach the brain for processing.

Who is a Candidate for a Cochlear Implant?
Range of hearing for a cochlear implant candidate.
Adults (18 years+)• Severe-to-profound, bilateral sensorineural hearing loss• Less than 50% speech recognition with hearing aids on
open-set sentence recognition
Children (12 months - 2 years)• Profound, bilateral sensorineural deafness (> 90 dB HL)• Little or no benefit from hearing aids
Children (2 years - 17 years)• Severe-to-profound, bilateral sensorineural deafness • Little or no benefit from hearing aids
Who is a Candidate for a Cochlear Implant?
• Audiologic Evaluation
• Medical Evaluation
• Speech Language Evaluation
• Psychological Evaluation
• Educational Evaluation

Child
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
• Determine cause of hearing loss • Assess status of middle ear & cochlea• CT scan/MRI• Counseling
• Hearing loss• The surgical procedure
• Typically out-patient and performed by an otolaryngologist (ENT) or otologist (ear specialist)
• Post-surgical considerations
• Bilateral Implants• Industry trend• Simultaneous vs. sequential• Benefits:
• Improved directionality• Improved listening in noise• Clarity of speech• Developmental
Bilateral Cochlear Implants
Speech & Language Evaluation• Areas assessed
• Vocabulary - knowledge of single words• receptive • expressive
• Language - word combinations, grammar• receptive
• expressive • Articulation/Intelligibility• Reading skills
Developmental Evaluation
• Assessment of non-verbal & verbal IQ• Verbal IQ assessed when appropriate
• Counseling for family• Impact of hearing loss on the family unit
• Assessment of child’s learning style• Assessment of any other underlying
issues• Serves as a baseline evaluation
Educational Evaluation
• Areas to consider:• Communication methodology• Support services • Speech/language and
auditory skill development• Professional training

How is a Cochlear Implant Different From a Hearing Aid?
Hearing Aid Cochlear Implant
Acoustically amplify sound.
Convert sound into electrical signals.
Rely on the responsiveness of healthy inner ear sensory cells.
Bypass the inner ear sensory cells and stimulate the hearing nerve directly.
A Cochlear implant system consists of two main parts:
Internal Implant
External Equipment

HiResolution™ SoundWhat do parents want for their child?
• 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 implant.
• The implant delivers the sound to the electrodes.
• The electrodes stimulate the hearing nerve.
• The hearing nerve sends the signal to the brain where it is perceived as sound.

Audiologic Management
• Goal is to assure access to sound adequate for auditory development
• Programming or “mapping” of the cochlear implant system
• Assessments at regular intervals to track auditory development
• Age-appropriate techniques & materials

Rehabilitation is KEY
Parent Commitment
School Support • Understand what a cochlear implant is & equipment
troubleshooting • Assist in the management of the device and child• Perform behavioral listening checks on a daily basis• Know where to find support and resource materials• Maintain communication between the student’s parents, teachers and cochlear implant center
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 important rehabilitation.
• Parent commitment and school support are necessary components to ensure a child’s success with a cochlear implant.
