Computational biomechanical analysis of postoperative inferior tibiofibular syndesmosis: a modified modeling method.

abstract：:A three-dimensional finite element model is developed for the simulation of the sound transmission through the human auditory periphery consisting of the external ear canal, middle ear and cochlea. The cochlea is modelled as a straight duct divided into two fluid-filled scalae by the basilar membrane (BM) having an or...
