(Bone Anchored Hearing Aid) Baha Ear Surgery Korea
What is Bone Anchored Hearing Aid surgery in Korea (BAHA)?
The BAHA(bone anchored hearing aid) System utilizes your body’s natural ability to conduct sound. Bone, like air, can conduct sound vibrations. For people with hearing loss, this provides another pathway to perceive sound. Typical hearing aids rely on air conduction and a functioning middle ear.
In cases where the middle ear function is blocked, damaged or occluded, the BAHA (bone anchored hearing aid) system may be better option as it bypasses the outer and middle ear altogether. Instead, sound is sent around the damaged or problematic area, naturally stimulating the cochlea through bone conduction.
When someone has lost most of the hearing in one ear, but has normal hearing on the other side, the BAHA system works to reroute sound to the better ear. It uses our body’s natural ability to conduct sound through bone to deliver the signal to the better hearing ear.
Once the cochlea receives these sound vibrations, the organ “hears’ in the same manner as through air conduction; the sound is converted into neural signals and is transferred to the brain, allowing a BAHA recipient to perceive sound.
How is works?
- A sound processor picks up sound vibrations.
- An abutment is attached to the sound processor and the implant. The abutment transfers the sound vibrations from the processor to the implant.
- A small titanium implant is placed in the bone behind the ear where if fuses with the living bone. This process is called osseointegration. The implant transfers the sound vibrations to the functioning cochlea.
What does the sound processor look like?
The BAHA Sound Processor snaps on to the abutment. The processor is small, discreet and is available in a variety of colors. The volume controls are conveniently located for easy adjustments.
Titanium Implant More about Osseointegration. The founder of bone anchored hearing aid surgery is the Branemark system. In the early 1960s Professor Branemark discovered that titanium provides an excellent material for implantable devices. Titanium is accepted by the human body and forms a bond with surrounding bone.
This is a process he termed “osseointegration”, which takes place as the titanium implant integrates and forms a permanent structure with the living bone. The process of bone osseointegration is also the foundation for dental implants. This system has been developed not only for BAHA ear implant surgery but also for Cochlear’s craniofacial reconstruction system, Vistafix.
What is the different from conventional hearing aids?
Conventional hearing aids conduct air sound, but BAHA (bone anchored hearing aid) system uses bone conduction. BAHA improves hearing level highly with less amplification and is comfortable without blocking your ear canal. One study shows that prior conventional hearing aid uses prefer BAHA around 89%.
What’s different from conventional bony hearing aids?
Conventional aids band type or glasses type but BAHA uses direct osseteo-integration. So baha ear surgery provide clear sound and no need of extra lines and extra pressure.
Who is candidate for baha ear implant surgery in Korea?
- Bilateral congenital aural atresia
- Impossible cases for hearing mold due to large meatus
- Not suitable for hearing aid due to consistent otorrhea and chronic external otitis
- Single side deafness
- Regain 360-degree sound awareness for people who are deaf in one ear
- Experience great sound with less distortion & feedback
- Experience sound without anything blocking your ear canal or any feeling of weight from a hearing aid on your ear
- Get a proven, clinically tested and documented hearing solution
- Benefit from reduced problems with ear mold allergies or chronic ear infections
- Try BAHA, before you decide to go ahead with surgery
Surgical Procedure and Process of bone anchored hearing aid
We perform BAHA with minimal invasive technique under local anesthesia. It takes approximately 30 minutes to an hour and 7 days later, stitch out will be done. You can put on BAHA after 2 months.
BAHA for children
For bilateral congenital aural atresia, BAHA soft band is recommended before surgery. It helps hearing improvements and our study <<<shows>>> (20 patients for 2 weeks wearing BAHA) that BAHA soft band provided clearer sound, less noise and patients were satisfied.
