A 14 year old boy fell and hit his head in the playground school. He didn’t lose consciousness. He has swelling and tenderness of the right cheek with a subconjuctival hemorrhage on his right eye. What is the most appropriate initial investigation?

The key is E. Facial X-ray. [There is no sign of basal fracture (Panda sign is suggestive of basal fracture, not subconjunctival hemorrhage- unless posterior border of hemorrhage is not visible) and no indication of CT scan (there are some criteria for CT scan which are not fulfilled here)].
