A 29-year-old man is brought to the ED after being struck on the right cheek during a rugby tackle. He complains of increasing discomfort when chewing and says his cheek “doesn’t look the same as usual.” Examination shows swelling over the lateral orbit and mild tenderness along the upper cheekbone. His eye movements are full, and there is no diplopia. He struggles slightly to open his mouth widely, which he attributes to pain. Imaging is arranged due to the mechanism. and shown below:
