Insertion insertion technique round window extended round window cochleostomy Cochleostomy Extended RW Round Window
Cochleostomy Extended RW Round Window 290º ± 60 320º ± 28 325º ± 60 Depth of Insertion
Current Opinion either approach: identify round window fully is acceptable can preserve hearing
Current Opinion round window approach: favoured in thin electrodes cochleostomy: favoured in anomalies pre-curved electrodes
