They Come In All Shapes And Colors
Ear MoldsSlide8
Types of Hearing Aids
Strongest <-----------> WeakestSlide9
Who are Hearing Aids for?
Hearing aids can be worn by people with all types of hearing loss,But they work best for people with Conductive hearing lossSlide10
Cost Range of Hearing Aids
The range of a hearing aid can cost anywhere from $3,000 to $6,500 a pieceInsurance should cover initial cost of hearing aidsSlide11
Damage to Hearing Aids
Standard things that cause damage to our electronics (water, animals chewing, small children etc.) will cause damage to Hearing Aids.Easily lost with small children.Insurance WILL NOT cover the replacement costs. Slide12
The Cochlear Implant: The History
In 1957, A. Djourno and C. Eyries in France, William F. House at the House Ear Institute in Los Angeles, F. Blair Simmons at Stanford University, and Robin Michelson at the University of California, San Francisco, all created and implanted single-channel cochlear devices in human volunteers.
In the early 1970s, research teams led by William House at the House Ear Institute in Los Angeles; Graeme Clark at the University of Melbourne, Australia; F. Blair Simmons and Robert White at Stanford University; Donald
Eddington
at the University of Utah; and Michael
Merzenich
at the University of California, San Francisco,
began
work on developing multi-electrode cochlear implants with 24 channels.
In 1977, Adam
Kissiah
,
a NASA engineer with no medical
background,
designed a cochlear implant that is widely used today.
In 1991, Blake Wilson greatly improved the implants by sending signals to the electrodes sequentially instead of simultaneously - this increased clarity of sound. Slide13
What Does is Look Like?Slide14
Surgery?
CIs are surgically implanted into the earThis is major surgeryAnytime you cut into the skull you are risking brain injuryThe surgery drills into the cochlea and leaves the machine in there in a spiral shape.They then place the skull back in place and install the inner transmitter.
Doctors place the skin over the inner transmitter and sew the opening closed.Slide15
When do you get one?
Depends on the parents.Deaf Culture is against implanting at a young age.Speech and language acquisition is against NOT implanting at a young age. They implant as young as 12 months; the FDA recommends 24 monthsIn Europe, they start implanting at 6 months Slide16
Cost of a CI
Exceeds $40,000 (each ear)Plus the cost of Pre and Post doctor visits post-operative aural and oral rehabilitation processspeech therapy and any other training needed to fully gain best usage of the CISlide17
Cochlear implants “last” roughly 20 years.
You might have to replace the cochlear implant at some point in those 20 years. You can implant each ear 2 times.Slide18
Can you hear with an implant?
It doesn’t sound like normal hearing; more like a robotCIs wearers must go through extensive training to learn to understand what they are hearingmost research shows there is very little significant difference between hearing aids and CIs in their ability to help the wearer “hear”Slide19
