CH. 14 - Implants Flashcards
when it comes to hearing technology, there are three main types:
-Hearing Aids
-Hearing Assistive Tech
-Implantable Hearing Tech
Three main types of implants
1) cochlear
2) bone-conduction
3) middle ear
word meaning “after acquiring language”
Adventitiously
a hearing technology that uses both a hearing aid device and an implant into the cochlear
hybrid cochlear implant
two types of bone conduction implants
transcutaneous
Percutaneous
two internal parts of a CI
1) receiver
2) electrode array
an adult who is a good candidate for a CI has __-__ bilateral HL, specifically __, and have already tried __
moderately-severe - profound;
sensorineural; hearing aids
children who are good candidates for CIs typically have __-__ bilateral HL, specifically __, and have tried hearing aids ___
severe-profound;
sensorineural;
consistently
newborns who quality for CI’s are ones with ___ HL
congenital
good candidates for hybrid CI’s are those who have fair ___ hearing but their ___ hearing can’t be helped by HA’s
low-freq; high-freq
Hybrid hearing aids use electrical stimulation via the ___ and acoustic stimulation via the ___
implant; hearing-aid device
what is this?
hybrid CI
something that compares pre-treatment to post-treatment RE HA’s
outcome measure
another name for bone conduction implants
osseointegrated device
two main types of candidates for bone conduction implants
1) Intractable or inoperable conductive HL
2) Single-sided (unilateral) deafness
with a bone conduction implant, a ___ is surgically placed in the ___ bone
screw; mastoid
most effective way to hear in background noise RE hearing devices
directionality
with a bone conduction implant for those with single-sided deafness, the implant is put on the side that is ____
deaf
what are five pros to middle-ear implants
-24/7 hearing
-Can’t be seen
-Minimal feedback
-Sleep and shower with it
-Great quality
what is the main disadvantage to middle-ear implants
Cost - insurance doesn’t cover
Good candidates for middle ear implants are people with __-__ HL, specifically ___, with good amplified __ __
moderately severe-severe; sensorineural; speech understanding
