Radiologic Signs of an Entrapped Orbital Fracture

In this 1-Minute Video, Dr. Julian Perry describes radiographic signs of an entrapped orbital fracture. He recommends looking at the fat plane between the inferior rectus muscle and orbital floor to see if the muscle is abutting the bone without intervening fat. A curved opacity beneath the floor and within the maxillary sinus is another indication of entrapment. Regardless of imaging, the clinical diagnosis of entrapment relies on clinical signs of motility restriction.
