Effects of the fibers distribution in the human eardrum: A biomechanical study
Gentil, F; Parente, M; Martins, P; Garbe, C; Santos, C; Areias, B; Branco, C; Paço, J; Jorge, RNThe eardrum separates the external ear from the middle ear and it is responsible to convert the acoustical energy into mechanical energy. It is divided by pars tensa and pars flaccida. The aim of this work is to analyze the susceptibility of the four quadrants of the pars tensa under negative pressure, to different lamina propria fibers distribution. The development of associated ear pathology, in particular th...

The influence of muscles activation on the dynamical behaviour of the tympano-o...
Gentil, F; Parente, M; Martins, P; Garbe, C; Paço, J; Ferreira, AJ; Tavares, JM; Jorge, RNThe human ear is a complex biomechanical system and is divided into three parts: outer, middle and inner ear. The middle ear is formed by ossicles (malleus, incus and stapes), ligaments, muscles and tendons, which transfers sound vibrations from the eardrum to the inner ear, linking with mastoid and Eustachian tube. In this work, a finite element modelling of the tympano-ossicular system of the middle ear was d...
