Abstract
In spite of the development of new technologies and treatments in the field of craniofacial surgery, the reconstruction of post-traumatic, post-ablative and congenital deformities of the facial skeleton remains a challenge. Complications, which in part can be attributed to an incomplete understanding of the biomechanical environment of the craniofacial skeleton, continue to result in significant rates of morbidity and re-operation. A subject-specific finite element model of a fresh frozen human craniofacial skeleton was developed and validated against strain measurement from 'in vitro' mechanical testing. The most accurate model was found to have a correlation of 0.73 against ' in vitro' data. The most accurate model assigned local cortical thickness measurements from CT imaging data. The developed model was sensitive to assumptions regarding the elastic modulus of cortical bone, but not the Poisson's ratio. Validated computational models have tremendous potential for providing valuable insights into the biomechanics of the human craniofacial skeleton.
