Abstract

•Cochlear implantation via the round window membrane (RWM) or a cochleostomy.•Sealing material: no additional sealing, muscle graft or carboxylate cement.•Hearing thresholds correlated with the amount of tissue formation.•The RWM approach resulted in less tissue formation than the cochleostomy approach.•Carboxylate cement sealing resulted in a strong bone formation in the cochlea.
