Candidacy Expansion and Improved Outcomes in Cochlear Implant Surgery

---

1.  Primary goals for future electrode design include: Reduced intracochlear trauma. Deeper insertion to access low frequency neurons. Greater operating efficiency (reduction in stimulus charge requirements). All of the above

2.  There is a positive correlation between CNC word score and: ST electrode location (reduced trauma) Insertion depth Proximity to the modiolus All of the above

3.  Children implanted < ___ months show: improved comprehension & expressive communication. 1 6 12 None of the above

4.  The soft surgical technique involves: Minimizing drilling on the cochlea. Opening the cochlear as late as possible and avoiding suctioning of perilymph. Use of lubricant during insertion (i.e., glycerol). All of the above

5.  Reducing Electrode-modiolar distance (EMD) will: Decrease spread of excitation in the cochlea. Increase stimulation currents. Increase psychophysical comfortable levels. None of the above

6.  In regards to cortical neuroplasticity, rapid proliferation for ___ years followed by pruning after 4 years of age. 3.5 5 10 12

7.  What does CAEP stand for? Cortical Advanced Electrical Potentials Cortical Auditory Evoked Potential Central Auditory Evoked Potential None of the above

8.  What is the expected latency for a P1 response? 0-10 ms 10-50 ms 50-300 ms 300-500 ms

9.  CAEPs evaluate the auditory pathway to the level of the: Primary Auditory Cortex Brainstem Cochlea 8th Auditory Nerve

10.  In SSD patients, CI voice quality can be very good if the apical electrode has accurate _______ with input signal. Signal-place mismatch Place-pitch match None of the above All of the above
