    Abstract
    In cochlear implants the round window is convenient for the electrode insertion into the scala tympani because the surgical approach is reasonably easy and the inserted electrode lies close to systematically organised nerve fibres in the spiral lamina. However, complications might occur when a poor seal, extensive tissue damage or surgical asepsis are present that lead to a reduction in the nerve fibre population which is needed for electrical stimulation. Published articles available do not describe the role of the window membrane in cochlear implants. Probably this can be referred to the finidng of abundant scar tissue in the window niche and around the electrode giving the impression of a safely implanted electrode. This study performed on seven cats over 5 months was concerned with morphological properties of the implanted window membrane at different stages after implantation. In addition, horseradishperoxydase was used as a tracersubstance to give data concerning the sealing properties of the implanted round window membrane.
