HiRes Ultra Series Recall: Failure Rates and Revision Speech Recognition Outcomes

Objective To report Advanced Bionics (AB) Ultra (V1) and Ultra 3D (V1) cochlear implant (CI) electrode failures and revision speech recognition outcomes for patients at a large CI program. Study Design Retrospective case series. Setting Tertiary referral center. Patients Patients receiving Ultra (V1) or Ultra 3D (V1) devices as of September 21, 2021. Main Outcome Measures Failure rate, revision surgery, speech recognition scores. Results To data, 65 (21.1%) of the 308 implanted devices are known failures, with 63 (20.5%) associated with the recent voluntary field corrective action (FCA). Average time to failure was 2.2 ± 1.1 years. Fifty-two patients (82.5%) elected for revision surgery. Among adults, immediate prerevision scores demonstrated a significant decrease from best-achieved scores with the faulty implant, with mean difference of −15.2% (p = 0.0115) for consonant-nucleus-consonant (CNC) and −27.3% (p
