[Histological study of the binding of Polycel and Ceravital implants to the stapes footplate in rabbits].

Five Polycel and five Ceravital implants were interposed between the stapedial footplate and the tympanic membrane in 10 rabbits. Four to 7 months later the connection of the prostheses to the stapes was histologically examined by temporal bone sections. The union of both types of prostheses to the stapedial footplate was achieved by remnants of crura, middle ear mucosa and connective tissue. Histology revealed a more stable connection of the Polycel prosthesis to the stapedial footplate.
