Brain
- Left frontal scalp hematoma extending into the lateral periorbital soft tissues.
- No intracranial hemorrhage.
Facial Bones
- Left periorbital hematoma.
- Blow out fracture of the left orbital floor and lamina papyracea with involvement of the infraorbital nerve and entrapment of orbital fat. Inferior oblique is also displaced inferiorly.
- Numerous gas locules seen within the orbital soft tissues.
- Mildly depressed left medial orbital wall fracture with opacification of the adjacent ethmoid air cells.
- Undisplaced fracture through the left zygoma.
- Minimally displaced nasal bone fracture, deviated to the right.
Case Discussion
There are two broad categories of blow-out fractures. Open door fractures (seen in this case) are a large and displaced fracture and are frequently comminuted. Trap door fractures are linear and hinged and minimally displaced. Trap door fractures typically occur in the pediatric population and have a high incidence of extra-ocular muscle entrapment. Other facial bone fractures are commonly present when there is an orbital fracture.
