Audiology Praxis: Cochlear Implants Questions With
Complete Solutions
Adults with prelingual hearing loss generally are not considered
good candidates for cochlear implantation, especially if?
Correct Answers if they do not use oral/aural communication
are open-set or closed set tests used to determine candidacy?
Correct Answers Open-set tests of spoken word recognition are
typically used to determine audiological candidacy.
Are speech perception tests helpful in determining cochlear
candidacy? Correct Answers Speech perception tests are most
decisive in determining the appropriateness of cochlear
implantation.
- open-set word or sentence recognition performance below the
average scores seen for cochlear implant recipients should be
considered for implantation.
Audiological evaluation of young children for cochlear
implantation assesses the ear's sensitivity to sound, and, if
possible, includes measures of auditory perception. Correct
Answers For the youngest children, parental reporting scales of
auditory listening behavior, such as the Infant-Toddler
Meaningful Auditory Integration Scale frequently have been
used to assess auditory skill development.
Can EABR be measured on all impant types and in both
adults/children? Correct Answers EABR can be successfully
measured using a variety of different implant types both in
congenitally deaf children and postlingually deafened adults
, Current FDA guidelines permit cochlear implantation in persons
age 2 years and older with what degree of deafness? Correct
Answers severe-to-profound deafness (i.e., pure tone average
thresholds of 70 dB HL or greater)
Current guidelines permit implantation in adults with open-set
sentence recognition scores of ? Correct Answers open-set
sentence recognition scores of approximately 50% to 60% words
correct.
Depending on the amount of ossification, the surgeon has
choices of technique to ?(re: array) Correct Answers maximize
the possibility of obtaining a full insertion of the electrode array
or of using a specially designed electrode array for the more
heavily ossified cochleas
Electrically evoked auditory brainstem response - EABR
Correct Answers a recording of the synchronous neural activity
in the brainstem that results when the auditory nerve is
stimulated.
For babies and infants the primary method for measuring
hearing sensitivity? Correct Answers VRA and auditory
evoked response audiometry are the primary methods of
measuring hearing sensitivity.
- Speech/auditory perception testing depends upon the age and
linguistic ability of the child.
For older children, open-set word and sentence tests are
employed to determine candidacy. Correct Answers open-set
