Coronal CT without contrast of the orbits obtained immediately after the injury in soft tissue (above left) and bone (above right) windows show a very small amount of soft tissue herniated into the roof of the right maxillary sinus. No fracture line was identified. Repeat coronal CT without contrast of the orbits obtained two days after the injury in soft tissue (below left) and bone (below right) windows now shows a large amount of soft tissue herniated into the roof of the right maxillary sinus.
The diagnosis was right orbital blowout fracture. In the operating room there was entrapment of the right inferior rectus muscle which was ischemic.
