Evaluate rates of Advanced Bionics Ultra 3D/Ultra cochlear implant failure in the setting of a worldwide device recall and report surgical and auditory outcomes after revision. Retrospective chart review was performed for adult and pediatric patients implanted with at risk devices at our center from 2016 to 2020. Device failure rates, surgical, and auditory outcomes were recorded and analyzed. Of 113 at-risk devices, 20 devices (17.7%) in 18 patients (two bilaterally implanted) were identified as failures. All devices were with mid-scala electrodes. Eleven patients (61.1%) were children and 7 (38.9%) adults. Twelve patients were found to have failing devices after reporting subjective performance decline; the remainder were prompted by manufacturer notification. All were revised, with the majority (83.3%) choosing the same manufacturer. All had uncomplicated original and revision insertions. Among adults, average word scores on the revised side were stable pre- to post-revision ( P  = 0.95). Patients with device failure due to this field action performed well after revision implantation. Patients with bilateral at-risk devices but evidence of unilateral failure may elect to undergo simultaneous empiric revision of the contralateral device. Three patients who elected to change device manufacturers on revision have variable results that require further investigation. Patients requiring revision for a device field action overall perform well. At-risk devices continue to require monitoring as a growing number are likely to fail over time.
