Study Summary
The purpose of this research study is to determine whether Auditory Brainstem Implant (ABI) can improve hearing in persons who are deaf in both ears and are not candidates for cochlear implants.
Primary Outcome
Average pure tone threshold measured 12 months post-operatively. Measured in dB HL, where a lower threshold indicates more sensitive hearing and a higher threshold indicates less sensitive hearing. We only included data from subjects that had auditory percept of any magnitude following ABI surgery (1/3 subjects).
Interventions
- DEVICE Nucleus 24 (discontinued) and ABI541 Auditory Brainstem Implants (ABI)
