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. Click here
for a detailed description of the lag technique.
There is a great deal of variability in the shape of the zygomatic arch. In
this case, the arch is a relatively straight segment.
