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.

• Cochlear implant candidacy• Candidacy guidelines• Steps to determine candidacy



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

• Speech Language Evaluation

• Psychological Evaluation

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.
