A Study to Evaluate the Effectiveness of a Dexamethasone Eluting Slim Modiolar Electrode in the Reduction of Fibrosis in a Newly Implanted Adult Population with Bilateral, Post-Linguistic, Moderate to Profound Sensorineural Hearing Loss


About this study

The purpose of this study is show the effectiveness of a dexamethasone eluting electrode in an adult population with post-lingual, bilateral, moderate to profound sensorineural hearing loss in the reduction of fibrosis (as measured by impedance) when compared to a conventional, non-dexamethasone eluting electrode and in the improvement of speech recognition from preoperative baseline.
