Technique for rigidity determination of the materials for ossicles prostheses of human middle ear
Keywords:middle ear, ossicles prosthesis, rigidity modulus
The theoretical analysis of a technique for rigidity determination of the materials for ossicles prostheses of human middle ear has been carried out based on the measurement of the acoustical velocity. This paper presents the results of rigidity modulus measurements for the ossicles prostheses made from the materials of different origin, based on which the known materials have been identified and a novel one has been suggested, namely foam polyurethane (PU foam-3). It has been recommended to utilize the polymer material in the case of substitution of the entire ossicles chain and the bioactive ceramics in the case of partial substitution.
