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. Retrospective case series. Tertiary referral center. Patients receiving Ultra (V1) or Ultra 3D (V1) devices as of September 21, 2021. Failure rate, revision surgery, speech recognition scores. 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 pre-revision scores demonstrated a significant decrease from best-achieved scores with the faulty implant, with mean difference of −15.2% (p=0.0115) for CNC and −27.3% (p<0.0001) for AzBio in quiet. By 3 months post-activation of the revised device, CNC (p=0.9766) and AzBio in quiet (p=0.9501) scores were not significantly different than best pre-revision scores. Overall, 15 of 19 patients regained or improved their best pre-revision CNC score. The current trajectory for FCA device failures is approximately 6% per year. Compared to manufacturer reporting, a high number of patients experienced hard failures of the Ultra (V1) and Ultra 3D (V1) devices. Early identification of failures is possibly due to diligent use of electrical field imaging (EFI) testing. Most patients affected by the FCA regain or exceed their pre-failure speech recognition score as soon as 3 months after revision surgery.
