Residual Hearing and Cochlear Implant Surgery Using a Standard Length Electrode Array

---

1.  All of the following may occur when a cochlear implant is placed inside the cochlea, EXCEPT? New bone formation Inflammation/fibrous tissue formation Regeneration of hair cells Loss of spiral ganglion cells

2.  All of the following may cause hearing loss when a cochlear implant is placed inside the cochlea, EXCEPT? Loss of perilymph Acoustic trauma from drilling on the cochlea Mechanical dampening effects from the electrode inside the cochlea Spiral ganglion cells pick up electrical signals from the cochlear implant

3.  Precurved cochlear implant electrodes may cause the following to occur inside the cochlea: Regeneration of hair cells Regeneration of spiral ganglion cells Breakthrough from scala tympani to scala vestibuli with damage to basilar membrane Regeneration of supporting cells in organ of corti

4.  All of the following are benefits of hearing preservation in cochlear implantation, EXCEPT: Worsened ability to appreciate music Improved hearing in noise Improved spectral discrimination/pitch perception Improved timing cues

5.  All of the following are benefits of hearing preservation in cochlear implantation, EXCEPT: Awareness of sound even when implant is not worn Less mechanical quality of sound Less dizziness than when hearing is not preserved Delays time to hearing with the implant

6.  All of the following are areas of research for hearing preservation for cochlear implantation, EXCEPT: Hair cell regeneration Different style cochlear implants Drug-eluting gels to promote hair cell growth Chemotherapy drugs

7.  Which of the following is an area of current research for hearing preservation in cochlear implantation? Pre curved cochlear implant electrodes Dexamethasone eluting electrode Chemotherapy drugs Bonebridge implant

8.  Which of the following is a benefit of hearing preservation in cochlear implantation? May allow opportunity for more advanced treatments in the future Delays time to hearing after device activation Worse hearing in noise Worsened ability to appreciate music

9.  If sufficient hearing has been preserved after cochlear implantation, which of the following is the best hearing option? Use of an over the counter hearing aid only Use of a hybrid cochlear implant (acoustic/electric) Use of a bone anchored implant Use of bonebridge implant

10.  What option is available if hearing is preserved after implantation, and then gradually deteriorates to a profound loss? Use of an over the counter hearing aid only Use of a cochlear implant (electric only) Use of a bone anchored implant Use of bonebridge implant
