Normal hearing relies on proper functioning of the three bones (malleus, incus and stapes) of the middle ear. If they are diseased or malformed they do not transmit sound properly and the individual experiences a conductive hearing loss. One form of surgical treatment is to replace the faulty parts with an ossicular replacement prosthesis. We are using finite element modelling as a means for studying middle ear biomechanics and designing new prostheses. The project aims to produce prostheses with improved functional characteristics. Accurate geometrical models are obtained from micro-CT images, as seen in the example above, which shows the stapes structure in great detail.
