To characterize failure rate and etiology after cochlear implantation; to identify predictors and describe outcomes after implant failure.Retrospective chart review and systematic review of the literature using PubMed and Embase.Academic Cochlear Implant Center.Four hundred ninety-eight devices in 439 distinct adult patients.Unilateral or bilateral cochlear implantation.Implant failure rate and etiology.A total of 32 devices (5.9%) failed in 31 patients encompassing the following failure types in accordance with the European Consensus Statement of Cochlear Implants: 17 device failures (53.1%), 11 failures due to performance decrement/adverse reactions (34.4%), and 4 medical reasons (12.9%). There was no significant difference in age, sex, or manufacturer between patients with and without failures. Twenty-five percent of patients with failure leading to explantation had childhood onset of deafness compared to 12.1% of patients with adult-onset hearing loss (OR = 2.42; p = 0.04). Performance decrement/adverse reaction patients had an older average age at implantation compared to device failure patients (mean 68.5 yr 95% CI: 59.9-77.1 vs mean 47.6 yr, CI: 39.9-55.3, p
