Getting Bone Anchored Hearing Aids
Getting this type of hearing aid starts with a surgical procedure that imbeds a titanium implant with an external abutment onto the skull. A sound processor is located in the abutment. This processor works as the transmitter of sound, from external sources, to the abutment and then into the titanium implant. The implant then causes the inner ear and the skull to vibrate. This vibration activates the nerves of the inner ear, and causes it to hear.
The process of imbedding the titanium implant is called osseointegration. Bone anchored hearing aids can only be used two to six months after the osseointegration procedure. This is typically an easy one-stage procedure, using only a small amount of anesthesia. Patients can leave after a few hours of rest. The intake of pain relievers may be required for a couple of days.
Osseointegration is a generally safe procedure, with a success rate of above 95%. Failure can be caused by infection – but then, doctors can try the procedure again after curing infections and other side effects. In many of these procedures, the surgeon will put in a second idle receptacle. This idle receptacle will not be used until first one is damaged or fails.
Unlike adults, babies and toddlers go through two stages for the osseointegration procedure. In the first surgical stage, doctors peel back a one centimeter by one centimeter section behind the child’s ears, and then drill holes for the receptors. After six to eight months, the second surgery is done to attach the titanium implant.
For both children and adults, the wounds are allowed to heal for a couple of months before bone anchored hearing aids can be attached and used.
Who Can Get Bone Anchored Hearing Aids
In general, bone anchored hearing aids are for patients who cannot use the conventional hearing aids. They may have inflammation or infection in their ear canal. They may also suffer from malformed ear canals or outer ears. This type of hearing aid is also prescribed for people with deafness only in one ear. Likewise, this type of hearing aid is for people who suffer from bilateral conductive hearing loss because of ossicular diseases.
Risks in Getting Bone Anchored Hearing Aids
Since surgery is involved in getting this type of hearing aid, the patient risks contracting infection while the wound is still unhealed. The wound needs to be cleaned daily. A topical antibiotic should be applied in the affected area as the wound heals. Likewise, care should be taken with the titanium imbed. This should be cleaned daily with a soft brush. Its surrounding areas should also me disinfected regularly.
Care should be taken in handling the hearing aids. Even when these are designed to come off their posts, a slight impact may damage them. Cochlear Limited is the only manufacturer of this type of hearing aid for now. They offer warranty and repair within a period of time.
How Much Will It Cost
In terms of the hearing aid unit alone, cost can reach up to US$5,000. however, with the additional cost of hospitalization and surgery, expenses can add up to $35,000, on the average.
Hearing Aid Models
Since Cochlear Limited is the only current provider of this type of hearing aid, there are limited models to choose from:
1. BAHA Classic and BAHA Compact – These models have been discontinued because of developments in BAHA technology. They remain in use but with limited repair options.
2. BAHA Cordelle – This model is for those with severe hearing loss. Sound is amplified more. The Cordelle model is made up of a transducer and an additional attached unit that is worn around the body.
3. BAHA Divino – This model is digital BAHA model with built-in directional microphone.
4. BAHA Intenso – This model is supposedly the more powerful and clearer model. Feedback issues have also been reduced.
Bone anchored hearing aids are clearly the choice hearing aid for those suffering from severe hearing loss, and outer ear and ear canal defects and diseases. Advancements have made the surgical procedures that go with this type of hearing aid relatively safe.Watch the video related to Hearing Aids

Help answer the question about Hearing Aids
Why are hearing aids so terribly expensive?I realize the technology has it's price but there are almost as many people who wear glasses that also use hearing aids, why is it still 4000 dollars and higher for two pieces of plastic to amplify sound? I call that a rip off.

i’ve got 70% loss in left ear and 68% in right ear so yeah.. any tips for me ( i dont want to wear them at school). I will get bullied
There is NO best trade or model since everyone’s hearing loss is different and the age onset is different. And digital and analog hearing aids are DIFFERENT. I prefer the analog so I have Oitcon.
I have a student with the BAHA. He wears the removeable one, but there is also a permeanant, implantable one. His functioning was much much better when he used it, compared to when he didn't. Depending on whether you have a straight conductive loss, or a mixed hearing loss, will depend on how much benefit you get out of it. The only other thing I can say is that at certain intensities and frequencies, the aid will slightly vibrate, and you will be able to feel that on your skin. Good luck!
Programs for private use are already on the web – and for free – and even more sophisticated than the “audiologist ones. They´re just a mythical branch who want to make too much money with haring aids that aren´t even worth 50 $.
i have 2 normal hearing aids and love it,,,
i dont like digital hearing aids because of different sound
If do you live in U.S.A. Go to a Sears Store to the Hearing Aid Department, they have the best, for you . If not, I’ll recommend a Hearing aid of German Trade. Those are the best !!!. Good Look !!!.
Excuse me Madam. Which one do you use? Which trademake? Can you recommend something?
I´ll grateful you. Thank you.
Unless you cna get the digital aid programmed for you dont buy from ebay. these aids need and must be programmed to your prescription
Hi! I’m from Germany and I’m learning the job of a hearing aid audiologist.
For the people who want to get hearing aids:
Just go to a hearing aid audiologist. You just will have problems with the hearing aid if you get it from eBay or other sites…
The first problem would be that the h.a. isn’t matched with your hearing loss and you won’t be able to program it, because you haven’t the right software and I think you don’t exactly know how much amplification you need on which frequences…
