Cochlear Implants
true or false: surgery is need with upgrades made to the external portion of a CI
false; no surgery is needed with upgrades
This is an example of what would contribute to a child being at a higher risk for hearing loss
-family history
-high billirubin levels (jaundice)
-premature birth
these are examples of behaviors that an infant could exhibit in response to sound in behavioral observation audiometry (BOA)
blinking
sucking response
looking up at audiologist
turning towards sound
The act of an individual pretending to have hearing loss to avoid responsibility or receive compensation is called this
malingering
atresiaplasty is a surgical intervention to create this structure
an ear canal
To get a cochlear implant, one must have this anatomical feature
auditory nerve
a child who presents with normal hearing but has difficulties understanding speech may have this disorder
Auditory Processing Disorder
name all four behavioral tests up for children up to 2 years of age
Sound field testing
Behavioral Observation Audiometry (BOA)
Visual Response Audiometry (VRA)
Conditioned Orientation Reflex (COR)
a patient with anxiety or other mental disorders who also have non-organic HL may be tested using this for more accurate results
OAEs
The semicircular canals are in this part of the ear
inner ear (three tiny, fluid-filled tubes in your inner ear that help you keep your balance)
For individuals without auditory nerves, this device is implanted instead of a cochlear implant
auditory brainstem implant (ABI): bypasses outer, middle, and inner ear
These tests can be used during infant hearing screenings
ABRs(Auditory Brainstem Response) and OAEs (Otoacoustic Emissions)
This type of behavioral test is administered to infants four months and older
Conditioned Orientation Reflex
In the Delayed Speech Feedback test, if the individual is faking their HL, they will respond in this way
they will have difficulty speaking and their speech patterns will be altered
the reason why the largeness of the tympanic membrane in comparison to the smallness of the ossicles is important
it serves to amplify sound by 20-30 dB
Cochlear implants need these two components to function
surgically implanted internal processor and worn external portion
Behavioral tests, physiological tests, developmental measures
visual response audiometry is a behavioral test that can be administered to children in this age range
6 months and older because the child needs to be seated and have head control
When conducting the stenger test, an individual who is faking a unilateral hearing loss will respond in this way
they will not raise their hand because they can't tell which ear the sound is playing in
The acoustic reflex is triggered by noises over this dB
85 dB
Name three considerations for cochlear implant eligibility for pediatric patients
-age: minimum 9 months old
-weight: must be a certain weight for anesthesia
-severity of HL: bilateral severe to profound sensorineural HL
-Limited benefit from binaural amplification
Explain the 1-3-6 rule
Proper screening by month 1
Diagnosis by month 3
Amplification for HL/Enroll in early intervention by month 6
When operant conditioning for the child’s response to sound is not fully established or is inconsistent, the audiologist records these instead of thresholds
Minimum Response Levels: the “best” response obtained to the sound, rather than a threshold estimate
name three signs of non-organic HL in routine hearing tests
Poor test-retest reliability
Difference between speech reception thresholds and pure tone thresholds
Lack of cross-hearing
Discrepancy in unmasked bone conduction
This type of tympanogram indicates disarticulation of ossicles and the tympanic membrane hyper-reacts because there is no resistance from the ossicular chain
Type A sub D
