Implant Characteristics

Many materials have been used for ossicular substitution or reconstruction. The ideal prosthesis for ossicular reconstruction should be made of material that maintains its shape, rigidity, and acoustic properties, as well as being cost-effective. This material should also be biocompatible, safe, and easily inserted and modified (Table 19-1).
