Round window insertion of precurved perimodiolar electrode arrays: How successful is it?

Abstract

Hypothesis: The goal of this human temporal bone study was to assess the safety and efficacy of round window insertion of the Cochlear Contour Advance electrode and identify any anatomic obstacles that may affect its insertion. Background: Minimizing intracochlear trauma during electrode insertion reduces the risk of losing residual hearing. The Contour Advance electrode is designed for insertion via an anteroinferior cochleostomy, in which drilling causes a degree of inner ear trauma. If consistently successful round window insertions are possible with this electrode, it would allow for better perimodiolar positioning in the basal turn and greater likelihood of hearing preservation.
