To whom it may concern:
I am writing to express my support for continuing and
expanding the use of cochlear implants in adult patients with hearing loss. I
have extensive personal experience in the use of cochlear implants to
rehabilitate sensorineural hearing loss in children and adults. My research has
specifically focused on performance outcomes in adult patients with particular
attention to the elderly. Our program implanted 92 patients in calendar year
2010, consisting of 52 adults of which 21 were over the age of
60.
Our recent work (reprint is attached) looked at cochlear
implant performance in the elderly. The salient results are:
1)
All our subjects over the age of 65 showed
improvement in speech perception after cochlear implantation.
2)
Performance was directly related to pre-implant
performance. Meaning, those scoring between 41-60% on pre-operative sentence
testing did significantly better than those scoring between 21-40% which in turn
did better than those scoring between 0-20%.
3)
Elderly patients show slightly worse performance
than younger adults, particularly in noise.
The conclusions from these results are:
1)
Cochlear implants are highly effective in
providing useful hearing in elderly patients
2)
Early intervention with cochlear implants (i.e.,
better speech scores (sentences up to 60%)) leads to significantly better
outcomes
3)
Bilateral implantation, and its ability to
improve performance in noise, may be most useful in older
patients
In short, the evidence is strongly in favor of continuing
support for cochlear implantation in older adults, should expand the criteria to
include those with sentence scores up to 60%, and should include bilateral
implantation.
