Abstract (EN): The human ear is a complex biomechanical system and is divided by three parts: outer, middle and inner ear. The middle ear is formed by three ossicles (malleus, incus and stapes) that amplify the sound sending the sound waves to the inner ear. However, the ossicles can suffer from several damages, for example, the Otosclerosis, being a need the application of mechanical prosthesis, by chirurgic intervention, keeping the right travel of sound wave. In this work, a finite element modelling of the middle ear was made. For this propose, we show an approximate 3D solid model of the ossicles and eardrum for a normal ear. The discretization of these components was made with tetrahedral solid elements, using ABAQUS program. The connection between ossicles was made using contact formulation. The obtained results on the eardrum, considering different acoustic pressure values, are compared with the results of the model without ligaments.
