BONEBRIDGE Bone Conduction Implant in Adults
Study Details
Study Description
Brief Summary
Approximately thirty subjects with mixed or conductive hearing loss, meeting FDA-cleared candidacy criteria for the BONEBRIDGE, will be implanted and followed for three (3) months post-activation to assess safety and effectiveness of the BONEBRIDGE implant.

Outcome Measures
Primary Outcome Measures
- 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.
- 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
- 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.
- 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
- 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.
- 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.
Eligibility Criteria
Criteria
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

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
