BONE CONDUCTION HEARING AID, A-transcutaneous-BCI-system-with-an-implanted…
BONE CONDUCTION HEARING AID
Types of BCHA
Non Surgical (Extrinsic)
Can be worn on a headband or attached directly to the skin with adhesive
best fitted for children who not old enough for surgical procedures or adults who have hearing loss can not undergo surgery
Surgically implanted (BAHA)
Internal component
External processor
Types of surgical BCHA mechanism :
Percutaneous Devices
Directly coupled to the bone by permanent skin penetration
Need time to heal after the penetration
Higher chances of getting infections
Earliest invention
Transcutaneous
Active Transcutaneous Devices
Audio processor, microphone, battery and digital signal processor is attached to the intact skin.
External processor attach to magnetic induce
Lesser possibility of getting infection
Implanted transducer in direct contact with bone
Passive Transcutaneous Devices
Audio processor consists of microphone, battery and transducer
Sound processor is attached to a sound processor magnet
External audio processor that is attached with implanted magnet and titanium implant
Lesser possibility of getting infection
BAHA mechanism
1) sound processor captures sound in the air
2) sound processor turns the sound into virbations
3) Sends them through an implant via abutment or a magnet connection
3) the implant transmits the vibrations through the bone directly to inner ear bypassing the outer and middle ear
Examples of surgical BCHA
Passive Transcutaneous Devices
Cochlear Bone anchored hearing aids
Sophono alpha 2 MPO
Cochlear Baha Attarct
Active Transcutaneous Devices
Med-El bonebridge implant system
Cochlear Osia 2
Percutaneoous Devices
Oticon Ponto
Cochlear BAHA Connect
