Wk9-23-Oticon Ponto

Question 1

Which type of BC device is the Oticon Ponto?

Answer 1

Similar to the BAHA

- pericutaneous transmission

Question 2

Why did Cochlear sue Oticon?

Answer 2

For creating a universal abutment that would fit either the Ponto or BAHA

Question 3

What are the 3 levels of power for the Ponto?

Answer 3

Ponto 3 - up to 45 dB loss
Ponto 3 Power - up to 55 dB loss
Ponto 3 SuperPower - up to 65 dB loss (comes in only 1 piece, unlike BAHA)

Question 4

Which smartphones does Ponto 3 have an app for?

Answer 4

iPhone and Android

- can also be connected with other devices, but only through an intermediary neck loop

Question 5

Ponto 4 only comes in what power level? What kind of connectivity does it have?

Answer 5

Up to 45 dB los

- 2.4 GHz wireless using Oticon ON app

Question 6

What type of “geometry” does Oticon use for its implant and why?

Answer 6

Otogrip geometry

• more surface contact
• improved stability and reliability

Question 7

The OptiFit shape of the Ponto abutments fits naturally to the circular incision made by MIPS (minimally invasive ponto surgery). What does this allow?

Answer 7

No pockets or pathways surrounding the abutment

• MIPS is suture-free, under 10 minutes, and local anesthesia
• minimized post-op complications
• tailor-made instruments for the surgeon (only remove the soft tissue absolutely necessary)

Question 8

Why does Oticon allow for some abutments to be angled?

Answer 8

For cosmetic correction and reduction of feedback

• *Screw is green to allow for easy identification of Ponto
• universal interface and always backwards compatible

Question 9

How long post-op do patients need to wait for osseointegration of the Ponto abutment?

Answer 9

2-4 weeks

Question 10

How could we get feedback with bone anchored devices?

Answer 10

4 ways:

1. Structure borne mechanical FB - transducer vibrations are mechanically transmitted through the housing to the mic
2. Acoustic FB: caused by sound radiated from the skull bone and from HA housing is acoustically transmitted back to mic
3. Electrical FB: voltage fluctuations in the output amplifier are electrically transmitted to the preamplifier or the mic w/in the electric circuit
4. Magnetic FB: magnetic leakage from the transducer are magnetically transmitted to the mic or telecoil

Question 11

T/F: Ponto has apparently the widest bandwidth in the industry

Answer 11

True (according to their website)
