Presentation
Accident.
Patient Data
Communited right frontal bone and sinus as well as orbital roof and superior rim fractures. Angulated displaced fractures fragments are seen projecting downwards within the orbit indenting the superior rectus muscle.
Communited mildly depressed left orbital roof fracture.
Fracture of the left zygomaticomaxillary attachmnet with fracture of the anterior and lateral maxillary walls, inferior orbital rim fracture and left maxillary hemosinus.
Fissure fracture of the left sphenoid wing.
Bilateral mildly displaced nasal bone fractures.
Bilateral frontal lobe contusions (larger on the right side).
Communited right frontal bone and sinus as well as orbital roof and orbital rim fractures.
Angulated displaced fractures fragments are seen projecting downwards within the orbit indenting the superior rectus muscle.
Case Discussion
A blow-in fracture is an inwardly displaced fracture of the orbital rim or wall resulting in decreased orbital volume.
Orbital blow in fracture are divided into:
pure or isolated blow-in fracture which represents an inferior displacement of the orbital roof without involvement of the supraorbital rim or the frontal sinus”, and is thought to be the result of increased intracranial pressure, a shift of the cranium, or a shift of the intracranial contents
-
or impure fractures, where the orbital rim itself was disrupted
