Menieres and Baha/ Osia evaluation

Hi all,

After trialing new hearing aids and still being unable to hear clarity with background noise etc my ENT sent audigram file to see what the implant specialist thought of my file/ history. To my dismay; they called back from the hospital and said I was a definite candidate for either the Baha or the Osia with my conductive loss. So much so that I have an appointment for the end of July, which includes meeting the surgeon.
My biggest fear is the fluctuating loss I have , won’t get sorted. I’m ok missing words if they say that they can’t guarantee a better sound quality and speech understanding !would rather deal with hearing aids then surgery if so!!!

Has anyone gone through something similar?

Thoughts and or recommendations?

At my age I want to be as active as possible and willing to do what I can to hear better - especially when it keeps dropping and getting worse!!

Maybe I’m overreacting but the frustration of not being able to hear clearly while out for dinner etc is beyond but also embarrassing!!!

Lastly, do you have relearn hearing (like I hear a cochlear implant) or is I like getting a new hearing aid?

Thanks in advance and apologies for the long post!!!


Never knew menieres could cause a conductive loss, thought it was always a SN loss.

I admin a Deaf FB group and someone wore a cochlear 5 SP for over two years but has just had a cochlear implant fitted as her loss got too bad for a BAHA.

Your SN loss seems to be around 40 dB so your conductive loss must be near normal hearing which means you’ll get great benefit from a BAHA etc.


I have the Osia. It’s fabulous, especially for speech. I have entirely conduct8ive loss. As a result, the Osia, or any Baha implant, boosts volume and upper level frequencies more than my BTE aids. The surgery for the Osia is trivial. They do not go into the ear at all. So there is Zero danger of messing up any of your ear structures. The device is attached to the outside of the mastoid bone, just under the skin. Other devices use a post the screws into the bone and protrudes slightly out from your skull. Have no fears! The Osia pretty much restored my mid to high frequency range to normal levels. But I ahve a perfectlty functional auditory nerve.

Just realized I never updated my audiogram. Should be updated now. Appreciate the feedback.

You also need a working cochlear or near working cochlear for a BAHA or Osia to work. Otherwise if you didn’t have a working cochlear, only a cochlear implant would work.

John ask the surgeon -
•Which devise has less infection rate. I know the BAHA does get infected frequently. I don’t know anything about the Oscia though.
• Are either of the devices MRI compatible?

I have 2 friends that had a BAHA, both had to eventually get a CI due to frequent infections. The infection occurs around the abutment, where the HA attaches to the implanted portion.

Good luck at your surgeons appointment.

Supposedly Cochear has a version of the Osia that is MRI compatible, but hasn’t released it yet. My surgeon was blase about the mri issue. He said there were work arounds for that.
As to infections: I visit a BAHA forum. A good number of people who have the post/abutment style BAHA report infection issues. But the site self selects for people having issues, in a way, so it’s hard to say how common this is. The Osia doesn’t have this issue, which is great.

Jeffrey I have a CI 5 series array which is not MRI compatible. The 6 series array is compatible, my surgeon advocates magnet removal always. As the head wrapping method isn’t always successful, the magnet can flip still. If it flips it becomes an emergency situation, which would be extremely painful and one that no one wants. The only really safe workaround is magnet removal, then replace it and reactivate again.

Good point! It could be that the ‘work around’ my surgeon mentioned was jsut that, removal of the the magnet. My understanding was that the problem was the magnet created a cloud in the imaging around itself. I hadn’t heard of the magnet flipping. Wouldn’t want that!
Maybe contact cochlear and enquire into the status of their MRI compatible Osia release date.

Jeffrey the problem is the magnet strength. The MRI is a Magnetic resonance imaging, so anything magnetic will move unless it’s firmly supported. The Nucleus plus magnets (6 series) are a lot weaker, therefore safe for MRI 1.5 Tesla’s.

Hi, I’m Lindsey, an audiologist with Treble Health, and I’ve been an audiologist specializing in tinnitus for 12+ years. Typically if you are a candidate for a Baha device due to a conductive loss the sound is clear enough to hear in background noise when using the device. You should be able to trial the Baha device using a headband just to get an idea of what it would be like (not exactly but close). Like hearing aids, the Baha will take some getting used to but it is not as involved of a relearning process as a cochlear implant would be. This adjustment period also depends on other factors, such as how long you’ve had a hearing loss, your age, etc.
