Zygomatic arch fracture, where the posterior fracture extends to the temporal bone

Options to consider for arch reconstruction

The illustration on the left represents a zygomatic arch fracture, where the posterior fracture extends to the temporal bone. In a situation like this, with fractures at multiple levels, a longer plate is needed.
In this case a lag technique was used to secure the posterior segment of the arch to the temporal bone. Extreme care needs to be used to make sure that the drill does not penetrate the calvaria, and does not violate the temporomandibular joint. A drill bit with stop is recommended.

There is a great deal of variability in the shape of the zygomatic arch. In this case, the arch is a relatively straight segment.
