Evaluation and Comparison of the Mechanical Behaviors of a Middle Ear Prosthesis using the Finite Element Method

Advancements in audiology and medical engineering have generated growing interest in enhancing titanium implants for middle ear restoration. In our study, we employed a finite element model of the middle ear to assess the behavior of the TORP prosthesis and the stapes under an acoustic pressure of 90 dB across a frequency range of 250 to 8000 Hz. The results were compared to experimental measurements obtained using a Doppler-effect-based laser vibrometer while varying the materials of the prosthesis to evaluate their mechanical impact. A satisfactory correlation between the simulation and experimental measurements validated our model.
