Abstract
In order to predict and evaluate injury mechanism and biomechanical
response of the facial impact on head injury in a crash accident. With the
combined modern medical imaging technologies, namely computed tomography
(CT) and magnetic resonance imaging (MRI), both geometric and finite element
(FE) models for human head-neck with detailed cranio-facial structure were
developed. The cadaveric head impact tests were conducted to validate the headneck finite element model. The intracranial pressure, skull dynamic response and
skull-brain relative displacement of the whole head-neck model were compared
with experimental data. Nine typical cases of facial traffic accidents were
simulated, with the individual stress wave propagation paths to the intracranial
contents through the facial and cranial skeleton being discussed thoroughly.
Intracranial pressure, von Mises stress and shear stress distribution were
achieved. It is proved that facial structure dissipates a large amount of impact
energy to protect the brain in its most natural way. The propagation path and
distribution of stress wave in the skull and brain determine the mechanism of
brain impact injury, which provides a theoretic basis for the diagnosis, treatment
and protection of craniocerebral injury caused by facial impact.
