cochlear implant, failure, reimplantationAbstract
Introduction: Cochlear implants have proved their clinical efficacy and have overcome a routine treatment for profound sensorineural impairment. More than thirty years pass since the first cochlear implant was used. These years, and the increasing number of implanted devices, have shown however some limitations and technical failures. These electronic device failures are unpredictable and sometimes difficult to diagnose.
Description of two cases: The authors present two cases to illustrate failures of the intracochlear device. Both cases required a cochlear reimplantation surgery.
Discussion and conclusion: There are multiple causes for intracochlear device’s failure. Management of implant failures, including revision surgeries, is becoming an increasingly important part of cochlear implant program activity.
