[WIll there ever exist the ideal auditive prosthesis for the reconstructive surgery of the middle ear?].
The AA. of the paper review the several materials used for the reconstruction of the middle ear ossicular chain. They inform about each material, including the auto- and homologous grafts of ossicles, cortical bone and cartilage. Palavit, Polyethylene-90, Teflon, metallic implants. Porous plastic materials: Proplast, Plastipore and Polycel. Bioactive ceramic prosthesis (ceramics of aluminium oxyde): Frialit and CORP. Bioactive vitroceramic prosthesis: Macor, Bioglass and Ceravital. Also bioactive of phosphate of calcium: Hydroxyapatite and Apaceram. Prosthesic material of nacre, coal-coal and Polymetacrylate (Ossiculoplast). The most important matter is to get an ear in the best conditions in order to accept the prosthesis, that is to say, a bed completely dry with no inflammatory clues in the tympanic cleft and with a correct functionalism of the Eustachian tube. The healthy ossicular rennants of the chain must be spared. The apatites, bioactive ceramica, are the prosthesis of the future owing to its similitude to the bone. Nevertheless will be difficult to obtain an absolutely inert material inside the middle ear, of the stability of the cleft is not secured.
