Q

How was maxillofacial trauma evaluated?

A

Each radiograph and ct was evaluated for the presence of any one of 27 predetermined potential traumatic injuries.
The case was scored as 1 if the finding was present t and 0 if it was not and results were then reported as a percentage of cases in which the finding was identified.
