Electrode Selection Options • Pre-curved • Banded • Short • Long • Double or split
Electrode Selection • Normal cochlea • “full” length • peri-modiolar • apical
Electrode Selection • Labyrinthitisossificans • partial insertion • compressed array • double array
Electrode Selection • Abnormal cochlea (incomplete partition) • not pre-curved • banded electrodes
Electrode Selection • Hearing preservation • Thin, flexible “atraumatic” electrodes • Short or long • Mid-scala
Electrode Selection • Increasing choice • Different manufacturers • Which gives best speech discrimination? • Which is best for hearing preservation? • Which is easier / safer to re-implant?
