Final Review

Question 1

Does not every clinic use the standard of 60 as the cutoff for CNC?

Answer 1

Yes
Some used 50 or 40

Question 2

Does the FDAs responsibilities extend beyond approval?

Answer 2

Yes
Post market approval (post-PMA approval)

Question 3

Do you do CNC first?

Answer 3

Yes, 60% or less you continue
It is a true hearing test
Do AzBio +10 dB SNR then (always done first)
Can do it in quiet (easier) or +5 (harder)
*you decide based on how the patient did on AzBio +10
If the patient is near the criteria threshold for the +10, perform the +5 next (because quiet is not a true representation of the listening environment)
Amplification or aided (a standard that you take to compare scores to post-implantation)

Question 4

Is SSD indication primarily focused on CNC?

Answer 4

Yes, 5% or less (want to prove that the ear is not aidable)
You can do the AzBio but you don’t need to (but you want it at zero)

Question 5

Is the protocol the same for SSD and asymmetric hearing loss?

Answer 5

Yes, based on CNC
You don’t have to do sentences

Question 6

What is a referral?

Answer 6

Might qualify for CI
60/60 guideline
Different than assessing them for candidacy

Question 7

Does a traditional candidate have bilateral loss?

Answer 7

Yes

Question 8

Do you improve speech quality when reducing channel interactions?

Answer 8

Yes

Question 9

What do more electrodes result in?

Answer 9

Better spectral resolution, but higher channel interaction
*opposite for fewer electrodes

Question 10

Does the position of the ground make a difference?

Answer 10

Yes
Determines monopolar and bipolar

Question 11

What is a short circuit?

Answer 11

Low resistance between electrodes
Touching each other (ground and active)
Short circuits will not show up with extracochlear ground (because they cannot physically touch)
