Ears eligible? - The CI candidacy process:
This test can be performed at +5 dB, +10 dB, and +15 dB SNR.
What is speech in noise testing?
You can’t rely on this to get you to buried treasure, but it can tell you how a CI is delivering stimulation to the user.
What is a map?
This part of the CI ensures that the processor connects to the internal portion of the device
What is the magnet?
Audiometric testing reveals that John has a profound SNHL in his right ear and normal hearing in his left ear. John has this type of hearing profile.
What is single-sided deafness?
This is the length of the average adult cochlea
What is 35mm?
During the CI candidacy process, audiologists commonly use these questionnaires to quantify an adult patient’s perceived hearing difficulties.
What are the CI QOL and SSQ?
This is the range of sound intensity and energy that a cochlear implant can deliver. It is typically </= 20 dB
What is electrical dynamic range?
This part of the CI delivers electrical stimulation to the SGCs and comes in four styles: perimodiolar, slim straight, full-banded, and split.
What is the electrode array?
Audiometric testing reveals that Jan has profound SNHL in her left ear and moderate SNHL in her right ear. Jan is not interested in any surgical devices for her hearing, so this device would be best for her.
What is a BiCROS?
John is audiologically and medically a cochlear implant candidate, but he lives alone and far away from family, and worries about the stigma around hearing loss. This healthcare professional can help John navigate his emotions around the device and hearing loss as he considers whether to go through with implantation.
What is a psychologist?
Before implanting a pediatric patient, the audiologist must ensure that the patient has undergone these processes for 3-6 months to demonstrate that they have done everything possible to develop auditory skills without implantation.
What are bilateral amplification and intense rehabilitation?
To ensure a pediatric user is using their optimal CI settings one year post-implantation, this is the optimal programming schedule.
What is every 3-6 months?
The transmitting coil sends the signal from the digital sound processor, through the skin, and to the internal receiver via this energy.
What is radio frequency?
This phenomenon demonstrates the importance of hearing with two ears, as it allows the brain to filter background noise more effectively.
What is binaural squelch?
This implantable device provides direct bone conduction stimulation to the user. Patients should be aware that it presents a higher risk for infection, due to the external abutment.
What is a percutaneous osseointegrated device?
Patients need this score on this speech test to be considered a hybrid device candidate (two part answer)
What is 80% or worse on CNC word testing?
If a CI patient complains that they can hear their processor whirring, then this program setting is too high.
What are T-levels?
Mary was diagnosed with cochlear ossification due to meningitis. This array type will be best for her.
What is a split array?
This CI manufacturer requires SSD/AHL patients to have a one-month trial of a CROS device before cochlear implantation.
What is MED-EL?
This is the most common vaccine recommended for CI users before surgery.
What is the pneumococcal meningitis vaccine?
While audiologists must be aware of insurance and FDA guidelines for CI candidacy, insurance does not specify these parameters for speech testing.
What are the sentence list, transducers, level, and SNR used while speech testing a potential CI candidate?
While programming, audiologists should be acutely aware to avoid this abnormal setting, because it can lead to the electrode short-circuiting and permanently deactivate that electrode.
What is low impedance?
Some cochlear implants now use this special type of magnet, with the poles on either side of the magnet’s diameter, making CIs MRI compatible.
What is a diametric magnet?
Unilateral CI users should consider this phenomenon when deciding whether to supplement their CI with a hearing aid in the other ear, as there can be significant imbalance and degeneration of the binaural auditory pathways.
How can unilateral CI usage impact the binaural auditory pathway?
Medical appointments can be very overwhelming for patients. Providers should be aware that patients forget this percentage of information immediately after an appointment.
What is 40-80%?
