Cochlear Bone Conduction Solutions candidacy, evaluation and fitting protocol

icon-green-candidacy.png

Candidacy identification

Assess audiological status, medical etiologies and impact to daily life to determine if bone conduction may be an appropriate solution.

  • Type of hearing loss
    • Conductive or Mixed hearing loss
      • Bone Conduction Threshold Pure Tone Average (PTA)* ≤ 55 dB
      • Patients with an air-bone gap (ABG) of > 30 dB PTA will experience significant advantages from a bone conduction system as compared to using an air conduction hearing aid.1
    • Single-sided deafness
      • Patients who have profound sensorineural hearing loss in one ear and normal hearing in the opposite ear
      • Patients who cannot or will not use an air conduction CROS hearing aid
      • Patient with contraindications for cochlear implantation
  • Common etiologies (microtia/atresia, chronic otitis media, middle ear dysfunction/ossicular disease, or conditions contraindicating reliable use of conventional hearing aids)
  • Daily interactions (struggle with communication, need for reliable and consistent hearing, and quality of life)

Demonstration and evaluation

Allow patients to experience hearing through bone conduction, providing patients with confidence in positive outcomes and appropriate expectations with a bone conduction solution.

  • Conduct an aided demonstration to allow patients to experience hearing through bone conduction.
  • Conduct a bone conduction evaluation to assess hearing and speech outcomes to assist with treatment determination, help predict outcomes, and collect a baseline for continued monitoring.
  • Set appropriate expectations for patient outcomes through counseling.

Treatment determination

Develop an audiological treatment plan in conjunction with medical treatment to address hearing needs of the patient.

Patient qualification
  • Conductive or Mixed Hearing Loss with PTA bone conduction threshold ≤55 dB
    (500, 1000, 2000, 3000 Hz)
  • No age requirement
  • Motivated to proceed with a non-surgical hearing solution

Additional recommendations for specific cases

Patient with factors that preclude an Osia 2 System

Consider the Cochlear Baha Connect System with Baha 6 Max Sound Processor

Baha Solution patient requiring additional clearance between their skin and the sound processor

Consider the Baha 6 Max Sound Processor with the 2mm Extended snap coupling, instead of the LowPro™ snap coupling

Patient with a bone conduction PTA threshold greater than 55 dB (500, 1000, 2000, 3000 Hz)

Conduct a cochlear implant evaluation for a Cochlear Nucleus System

Patient treatment, fitting and monitoring

Provide improved sound quality and speech intelligibility with comfortable wear for the recipient to use the device to their maximum potential.

  • Cochlear Fitting Software allows for customization of the bone conduction fitting prescription and configuration of the sound processor to match the patient’s thresholds, profile, and individualized listening needs.
  • Complete site checks as appropriate for the bone conduction solution at every visit and counsel the patient to perform regular site checks at home and report any issues immediately.
  • The same outcomes measures used for candidacy can be used post-fitting to validate the fitting and allow comparison to the pre-treatment baseline and previous post-fitting intervals to monitor performance.
  • Setting appropriate expectations is not only important in the candidacy process, but on an ongoing basis in order to help patients see their successes, identify their challenges, and continue to make progress.
  • Consider utilizing available Remote Care** solutions to provide quality care without the need for patients to visit the clinic.

When to consider a medically necessary upgrade for your patient

As a clinician, you are ideally placed to understand the changing needs of your patients as you provide support and guidance throughout their hearing journey.

Three pathways to a medically necessary upgrade:

  1. Upgrade to a medically necessary new sound processor
  2. Transition from non-surgical bone conduction solution to surgical bone conduction solution
  3. Transition from an implantable solution to a new or different Cochlear implantable solution
