Experimental: Bone Conduction Implant

All subjects will be implanted with the bone conduction implant.

Device: BONEBRIDGE
Bone Conduction Implant

Outcome Measures

Primary Outcome Measures

  1. Number and proportion of subjects experiencing device related adverse events [Up to three (3 months) post activation]

    Adverse events will be collected and reported throughout the duration of the study.

  2. Percent correct of words identified for sentences in noise in implanted ear [Up to three (3 months) post activation]

    AZBio sentence test recognition in noise scores will be calculated as percent correct of words in each sentence at unaided pre-operative performance through 3 months and reported as percentage points improved.

Secondary Outcome Measures

  1. Percent correct words recognition in quiet in implanted ear. [Up to three (3 months) post activation]

    CNC (Consonant Nucleus Consonant) words scores will be calculated as percent correct at unaided preoperative performance through 3 months and reported as percentage points improved.

  2. Unaided soundfield thresholds [Up to three (3 months) post activation]

    Subjects will demonstrate similar or better soundfield thresholds in the implanted ear compared to preoperative performance

  3. Signal to noise ratio in the implanted ear [Up to three (3 months) post activation]

    Subjects will demonstrate similar or better performance on the QuickSIN (Speech In Noise) in the implanted ear compared to preoperative performance.

  4. Unaided bone conduction thresholds [Up to two (2 weeks) post operative evaluation]

    Subjects will demonstrate stable bone conduction thresholds at the device activation interval compared to pre-operative bone conduction thresholds.

All
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  • Adults, 18 years of age or older at the time of implantation

  • Conductive or mixed hearing loss, defined as:

  • Conductive hearing loss with pure-tone average (PTA) for bone conduction thresholds better than or equal to 25 dB at 500, 1000, 2000 and 3000 Hz

  • Mixed hearing loss with PTA for bone conduction thresholds better than or equal to 45dB at 500, 1000, 2000, and 3000 Hz

  • Air-bone gap greater than or equal to 30 dB at 500, 1000, 2000, and 3000 Hz

  • Ability to benefit from amplification as defined by a monosyllabic (CNC) word score of 30% correct or better

  • Bilateral BONEBRIDGE can be considered if the difference in PTA for bone conduction thresholds is 10 dB or less between the right and left ears

  • Prior experience with acoustic or bone conduction hearing aids, unless candidate is unable to wear amplification for medical reasons

  • Able to complete testing materials in English

  • CT scan indicating the patient's anatomy is adequate to enable placement of the implant

  • Ability to undergo general anesthesia

  • Appropriate motivation and expectation levels

  • Stated willingness to comply with all study procedures for the duration of the study

Exclusion Criteria:
  • Evidence that hearing loss is retrocochlear in origin

  • Skin or scalp condition precluding use of external audio processor

  • Suspected cognitive impairment or organic brain dysfunction
