In case of loss of the auditory ossicular chain, the application of a middle ear prosthesis is necessary. For this prosthesis, a silicone pad shall be developed to minimize pressure peaks and for the prevention of forcing of the tympanic membrane. It is important to adjust the mechanical properties for best hearing quality. Therefore different siloxanes and additives like nanoporous silica nanoparticles are used. The latter also can act as drug carriers. The visco-elastic properties of the silicone can be changed significantly by slight variations of the composition.DFG/SFB/59
