Ponto, the Bone Anchored Hearing System: Providing Significantly Reduced Listening Effort as Compared to Skin Drive Solutions

View Course Details Please note: exam questions are subject to change.


1.  Which is not an example of a system that transmits sound transcutaneously
  1. Eyeglass-mounted bone conduction hearing aid
  2. Magnetic connection bone conduction hearing solutions
  3. A Ponto sound processor worn on an abutment
  4. A Ponto sound processor worn on a headband
2.  How much sound is attenuated, on average, when it passes through the skin?
  1. 10-20 dB
  2. 0 dB
  3. 20-25 dB
  4. 15-20 dB
3.  Some common aspects to address when a patient is considering a bone anchored hearing solution include
  1. Cosmetic outcome
  2. Comfort of daily wear and usage time
  3. Hearing improvement
  4. All of the above
4.  The SWIR test was developed to measure
  1. The patient's response to speech in noise
  2. The patient's listening effort
  3. The patient's ideal signal to noise ratio
  4. The patient's speech reception threshold in many conditions
5.  Why is the SWIR test conducted at a positive signal to noise ratio?
  1. Because even though the patient has full intelligibility, their listening effort can still be affected by the way sounds are transmitted
  2. Because it's a signal to noise ratio test
  3. Because only environmental situations with positive signal to noise ratios are realistic
  4. Because the test's measurements are too sensitive to background noise
6.  Which of the following statements about pediatric BAHS cases is true?
  1. Age at implantation is predictive of a child's speech perception, speech production, and language skills
  2. Prior to implantation, a soft band solution should be used with a power sound processor in order to provide sufficient output
  3. Children can also greatly benefit from the reduced listening effort provided by a direct sound stimulation system
  4. All of the above are true
7.  The Ponto Implant System consists of
  1. A 3mm or 4mm implant fixture, and an abutment of varying length dependent upon skin thickness
  2. A 4mm implant, and a 10-12mm adjustable abutment
  3. A 3mm or 4mm implant, a magnet, and an internal abutment
  4. A 4mm implant, and a 9mm abutment
8.  Which of the following is true?
  1. The most common surgery for BAHS includes tissue reduction
  2. Tissue preservation surgery provides better cosmetic outcome than previous approaches
  3. Tissue preservation surgery takes longer and is more problematic for patients
  4. BAHS surgery techniques have remained unchanged over the last ten years
9.  If an implanted Ponto patient must undergo an MRI
  1. The abutment must be removed
  2. One could expect a larger artifact in the image than if the patient used a transcutaneous solution
  3. One could expect a much smaller artifact in the image than if the patient used a transcutaneous solution
  4. Titanium implants do not create any image artifact.
10.  A percutaneous bone anchored hearing system
  1. Consists of an implant and a skin-penetrating abutment
  2. Has poor outcomes
  3. Provides less direct amplification than a transcutaneous system
  4. Makes it impossible to go swimming
