Learning Objectives: 1. To understand the mechanical effects of replacing the TM with other materials 2. To compare different materials used for reconstruction of the TM from a micromechanical sense.

We will present our results in cadaveric temporal bones measuring the vibration responses of overlaying cartilage at different sites on the TM, replacing different parts of the TM with cartilage, with perichondrium, with silastic, and with ointment.

We report both TM malleus vibrations and stapes vibrations.
