An evaluation of Cochlear's cochlear implant electrode array which passively elutes dexamethasone for a defined period of time to help reduce inflammatory responses.


The primary objectives of the pivotal evaluation is to show the efficacy of the dexamethasone eluting electrode through reduction in electrode impedances as compared to a standard electrode and the improvement of speech recognition from preoperative baseline. The secondary objectives are to assess the benefit-risk balance of a dexamethasone eluting electrode as similar to a standard electrode by comparison of adverse events and speech outcomes.
