Abstract

Due to the inaccessibility of the inner ear, direct in vivo information on cochlear mechanics is difficult to obtain. Mathematical modelling is a promising way to provide insight into the physiology and pathology of the cochlea. Finite element method (FEM) is one of the most popular discrete mathematical modelling techniques, mainly used in engineering that has been increasingly used to model the cochlea and its elements. The aim of this overview is to provide a brief introduction to the use of FEM in modelling and predicting the behavior of the cochlea in normal and pathological conditions. It will focus on methodological issues, modelling assumptions, simulation of clinical scenarios, and pathologies.

Figures

Figure 1
Human OC (approximately 12 mm from base). The osseous spiral lamina stops at the level of the insertion of the RM to the spiral limbus and is not in contact with the inner pillar. Thus, the OC rests entirely on the membranous spiral lamina (inner pilar) and the BM (specimen no. 280L, 10x, Human Temporal Bone Collection, UCL Ear Institute).

Figure 2
Human OC (approximately 12 mm from base). The fibers from the pectinate zone of the BM continue into the spiral ligament, where they are anchored (specimen no. F174R, 20x, Human Temporal Bone Collection, UCL Ear Institute).
