What is hearing aid orientation? Adjustment Period:
- to new hearing aid tech is an interactive process
between the patient and health care professional
-need to continue to wear them, to get used to it
-counsel wearer and their family members
- takes bout 2-3 weeks to adjust, then have a follow
up
- every state by law - 30 day trial for new HA &
typically comes with a warranty
What are hearing aid repair Repair Complaints:
complaints/how do hearing aids get -hearing aid is DEAD
damaged? -hearing aid cuts in and out (INTERMITTENT)
-hearing aid is WEAK
Damaged:
-Battery
-Debris / Moisture
-Operator Error
-Also: Hairspray, Cologne/Perfume, Hand Lotion,
Dry Skin flakes, Body Powder, dirt on your fingers,
Chemicals in work environment
,How is hearing aid trouble shooting Tools: Stethoscope, Battery tester, air blower, wax
performed? loop
Problems:
1. Check Battery
2. Work outside in - check for wax, take off ear
mold and tubing, mic, electrical issues
3. Use stethoscope
What is a cochlear implant (CI)? A cochlear implant is an electronic device that
performs the function of damaged or absent hair
cells by providing electrical stimulation to the
remaining nerve fibers
-bypasses the inner ear, turns sound into electrical
signals sent straight to the brain
How is CI candidacy determined? 1. Pre-op Info: Med eval, CT/MRI - if cochlea not
healthy enough then can't do it, Audiological eval,
ABR, HA eval - aided testing, speech&lang eval
2. Implant Center & Surgeon: not every ENT does
CI
3. Eval Team Members: Program coordinator, ENT
surgeon, audiologist, SLP, HI teacher, etc.
4. FDA Minimum Criteria - 12+ months, degree of
loss, limited benefits from HA, highly motivated
family
CI candidacy for adults?
, CI candidacy for kids? - ChIP - children's implant profile: as a team look at
areas of great concern
What factors affect CI outcomes? -Age when the hearing loss first occurred
-Age at the time of implantation: older - alrady
developed speech = better outcome, born with
profound HL - did not develop speech and did not
develop neural pathways = worse outcomes,
implant at birth = better outcome
-Time between hearing loss and implantation
-Hearing aid use before implantation - HA keeps
brain active processing sound = good outcome
What are the CI components? 1. Microphone
2. Speech Processor 3. Transmitting Coil (attached
with a magnet) 4. Receiver/Stimulator (attached
with a magnet) 5. Electrode Array - inside cochlea
CI surgery and programming - Prep. - Roleplaying w/ Kids
- Admission & Surgery - 2-5 Hrs.
- Recovery - 1-2 Hrs.
- Back to School in 5-6 Days
- No Swimming/Sports - 1 month
- First Hook-up - 3-4 weeks after surgery
- Initial Stimulation Responses
