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.},
