Recently a question came up in another blog about the late-deafened and the effectiveness of the CI. I felt the need to respond in here rather than on that blog, since the original post was about something entirely different. You can read it here.
I’ll quote what I’m responding to. One blogger asked,
For example, we have many people of the baby boomer age whose hearing is going down significantly as a result of their age, I don’t suppose that a CI would be an appropriate solution for them all? Your thoughts on that?
Another responded,
Most late-deafened adults can benefit from cochlear implants more easily than children because their spoken language is already well-developed as they grew up with normal hearing. As long as they receive appropriate rehabilitation after receiving a cochlear implant, they can benefit from it greatly. The ones who can’t benefit from it due to other health complications and other reasons like a friend of mine can use an FM system with their hearing aids, learn to read lips since they already have an established foundation of spoken language, or learn sign language if they choose to.
First, I want to clear something up. Many baby-boomers with severe hearing loss have experienced some kind of trauma not related to aging. People have accidents that damage parts of the middle and inner ear. Auto-immune diseases and drugs can also damage hearing. Some families are genetically prone to becoming deaf at an early age, with onset starting in early adulthood.
Second, it’s important to emphasize that MOST late-deafened adults who have been implanted don’t hear perfectly in many every day situations. They still use a variety of ALD’s, such as captioned television, Captel phones, light-activated fire alarms and door knockers, vibrating alarm clocks and hearing dogs.
Third, there seems to be a misconception among many that a CI will cure most everyone. I’ll list some of the reasons why some of my friends with hearing problems cannot get a CI.
1) Born deaf on one side, but only moderately to severely hard of hearing on the other. In this case, you might even be deaf enough to qualify for the CI IF you had once been hearing on that deaf side, but because doctors prefer implanting the ‘good’ side rather than the deaf side, they won’t take the risk while you still have some hearing left. Also, if one side has been without hearing and unaided for many, many years, they prefer to aid the side that has been aided. So, even if you were born with normal hearing, but went deaf on one side early, they prefer implanting the side that has had the most hearing for the longest period of time.
2) Born with parts of the middle or inner ear missing on one side and the development of hearing loss on the other side in middle-age.
3) Born with one misshapen cochlea and development of hearing loss on the other side in middle-age.
4) A problem with the nerve that leads from the cochleas to the brain. The nerve can be damaged during accident or disease.
5) Cochlear implant malfunction that prevents reimplantation. I’ve known a few this happened to.
6) Steep skislope loss, in which a person can be deaf to speech, but has good low tone hearing. (An experimental implant is in the works called a ‘hybrid’ but it hasn’t been approved by the FDA yet.) Skislope hearing loss is extremely common, and complicated to treat.
7) Health reasons. It may not be recommended to undergo an elective surgery. For example, I knew someone with heart problems who wasn’t allowed to get a CI until her heart was in better shape.
8) This is unusual, but I recently met someone with hearing loss and
hyperacusis. It’s so bad, that the sound of her own voice causes pain, so she signs. A CI won’t help. Her hearing is too good, though she can’t make much use of it because all sound is distorted.
9) Unstable hearing. My husband has Menieres. At certain times he is totally deaf, but then his hearing comes back partially, so he can’t be fit with hearing aids, much less an implant.
10) People who suffer from severe tinnitus that interferes with sound understanding, even though their hearing loss isn’t severe enough to qualify for implant.
Hearing aids sometimes don’t make much of a difference. There are times I turn my hearing aids off in noisy environments, because I feel I can lip read better without all the extraneous. distracting noise. I know someone else who rarely wears her hearing aids because she’s allergic to every kind of synthetic ear mold material known to man. Also some people have weird ear canals that make them difficult to fit. I have a problem with my right side. I honestly hate my hearing aids and don’t wear them as often as I can get away with it. It sort of bothers me when someone who has never worn hearing aids criticizes deaf people who don’t wear hearing aids. I recommend getting the full story before pronouncing judgement on them.
The final thing I wanted to point out is that it isn’t easy for all late-deafened to learn lip reading. Many highly intelligent late-deafened people really struggle with that, even though they may speak clearly. I’m not sure why that is, but I know some extremely bright people who grew up with perfect hearing who have difficulties lip reading.
Many middle-aged late-deafened people who became deaf before the CI was invented have adapted well with sign language. For them, perhaps gaining the ability to hear again is scary. They’ve already been through one major life-changing hearing loss, struggled to adapt, have moved on and are happy now. Why rock the boat?
I am following the blog post with interest. I didn’t watch the program. I agree that many benefit from the CI, probably even the majority of late-deafened, but there are a lot of people who simply can’t get one, and there’s so much misinformation out there. In my gut I feel it’s wrong to criticize someone’s personal choices when you don’t know the complete story.
