In which portion of the cochlea is ideal for electrode placement?
Scala tympani
What is the difference between a transcutaneous and percutaneous device?
Percutaneous device- attached via abutment
What does a hybrid device do?
To provide acoustic amplification to residual low frequency hearing and electric high frequency stimulation.
Name one variable that may affect the success of implantation of the geriatric population
- Age related changes in the peripheral and central auditory systems
- Long durations of hearing loss

What is the name of Advanced Bionics' adult sound processor?
Naida CI
When a patient adjusts the volume control on their cochlear implant processor, what are they actually doing to their programming?
Adjusting their c-levels
Name a known limitation of the auditory brainstem implant.
- Primarily stimulates low frequencies
- Stimulation often causes non-auditory precepts
- Electrode can migrate over time
CI users make better use of which of the following and why: ITDs or ILDs?
ILDs because they have limited access to low frequency sounds
Which speech recognition test has the highest ceiling effect (i.e. is the easiest)?

Which treatment plan is better for your patient: bimodal hearing or bilateral implants?
Research evidence reveals both are beneficial. Ultimately, it is your patient's choice and they know best.
What is the difference between on-label and off-label?
On-label refers to utilizing a medical device consistent with the indications for use set by the FDA. Manufacturers can only recommend using devices in an on-label manner. However, clinicians/physicians can opt to use devices in an off-label manner if it suits the patient.
