Blow-out fracture in right orbit floor with inferior extraconal subperiosteal hematoma interposed the inferior rectus muscle and orbital floor with impression on inferior rectus muscle and submucosal hemorrhage within right maxillary sinus are seen. Note the soft tissue swelling of the right side lower eyelid.
Case Discussion
Orbital inferior wall blow-out fracture is not usually accompanied by orbital hematoma and is more commonly seen in children as in this case. The hematoma can limit the movement of the inferior rectus muscle and clinically simulate the entrapment of the muscle within the fracture gap.
