Wk9-24-BoneBridge, ADHEAR, OSIA, Sophono, etc Flashcards
Is the Med-El Bonebridge classified as a Bone Conduction Implant or Bone Anchored Hearing Device?
Bone Conduction Implant
Why is the Med-El Bonebridge classified as a Bone Conduction Implant instead of a Bone Anchored Hearing Device?
The vibration goes through intact skin, but the bone transducer is located in the mastoid, under the skin. (Active transcutaneous device)
How long does Bonebridge surgery take?
30-60 mins
What are some of the benefits of Bonebridge?
- first active BC implant with intact skin
- quick surgery
- transducer under the skin = no damping of signal, reduced risk of skin infection, reduced likelihood of pressure pain
- still need 2-4 weeks before activation
What range of hearing losses is Bonebridge recommended for?
Up to 45 dB
**First one implanted at London Health Services!
What is the name of the Bonebridge speech processor?
Samba
What are some of the advanced features of the Samba?
- 16 independent compression channels
- sound smoothing
- speech and noise management
- adaptive directional microphones
- intelligent sound adapter classifier
- 5 different programs
- wind noise reduction
- wireless connectivity
- 250-8000 Hz bandwidth (flat response)
- 675 battery
How does the Bonebridge differ from the ADHEAR?
The Bonebridge is an active transcutaneous system located under the skin, whereas the ADHEAR is fixed from the outside, and transmitted through the skin.(Bone conduction hearing system)
- ADHEAR avoids pressure on the skin (less range?, Sticker price?)
What are the advantages of ADHEAR?
- non-surgical
- no pressure on the skin
- stays in optimal position
- simple handling
- cosmetics
What are the criteria for ADHEAR?
- Conductive losses c/ bone thresholds up to 25 dB
- Single Sided Deafness on the unaidable side for transcranial hearing
What are some of the characteristics of the ADHEAR adhesive adapter?
- optimized for sound transmission s/ pressure onto the skin
- can be worn 3-7 days
- water resistant
What types of HA technology does the ADHEAR include? What is one of the limitations?
Pros:
- automatic environmental classifier
- omni- and directional mic, FB cancellation, NR
- 4 diff programs
- pre-configured programs
- push-button program change
- 2 week battery life
Cons:
- needs WIRES to connect to audio devices (cellphones, BT streamers, FM receivers, Telecoil)
What are some other BC devices?
- ## cochlear osia (2019; active transcutaneous BC implant similar to Bonebridge, wireless connectivity, waterproof accessory)
How does the Cochlear Osia differ from the Bonebridge?
- Bonebridge uses a magnet and spring system that takes up more room, making it a poor option for children.
The Cochlear Osia uses Piezo Power to make it’s BC device slimmer. - Osia can fit up to 55 dB (vs 45 dB HL)
What type of implant is the Sophono?
Passive, transcutaneous
- up to 45 dB HL
- SSD
- 30 min surgery
- abutment-free
- internal and external components
- 5 screws securing implant
