Biomechanics of cranio-maxillofacial trauma.

The forces to the cranium and facial skeleton can be applied from an anteroposterior, superior, inferior and lateral directions. These forces with level and location of point of impact will determine the pattern of injury. Fractures of the cranium rarely extend into the region of facial skeleton. On the other hand, fractures originating in the facial skeleton can extend into the cranium. This has got implications as facial fractures are associated with head injury. Understanding the biomechanics of craniomaxillofacial trauma gives an insight in understanding the pattern of injury. We have briefly reviewed the literature and discussed biomechanics of craniofacial trauma, and how it influences head injury.
