Orbital Roof Fracture Radiology

This assessment is even more difficult when the orbital injury is associated with injuries involving multiple organs.

Orbital roof fracture radiology.

Common posttraumatic orbital injuries include anterior chamber injuries injuries to the lens open globe injuries ocular detachments intraorbital foreign bodies carotid cavernous fistula and optic nerve injuries. Communited mildly depressed left orbital roof fracture. Dr robert foley and assoc prof frank gaillard et al. It is a thin lamina separating the orbit anteriorly from the frontal sinus and posteriorly from the anterior cranial fossa.

The injury can be associated with a violation of the dura necessitating an intracranial approach. A three dimensional ct reconstruction demonstrated the extent and shape of the skull fracture fig. Orbital roof fracture icd 801 01 etiology. Displaced orbital roof fracture 3.

Assessing traumatic orbital injuries is an important challenge for radiologists. Angulated displaced fractures fragments are seen projecting downwards within the orbit indenting the superior rectus muscle. Most roof fractures are associated with other orbital fractures and result from significant head trauma as a high degree of force is required to fracture this portion of the orbit. As an isolated orbital roof fracture is a rare entity it is important to.

Ct scan revealed widening of the frontal bone fracture and the left orbital roof fracture with a hypodense cystic swelling in the left orbit and upper eyelid and left frontal lobe contusion. A orbital fractures can occur in isolation or with other fracture patterns. Isolated orbital roof fractures in adults are uncommon comprising 12 19 of all orbital wall fractures. This is typically caused by a direct blow to the central orbit from a fist or ball.

Orbital fracture pearls are as follows. Fracture of the left zygomaticomaxillary attachmnet with fracture of the anterior and lateral maxillary walls inferior orbital rim fracture and left maxillary hemosinus. Radiological considerations in the setting of orbital roof fracture it is important to fully assess the extent of the fracture including any radiographically apparent concomitant abnormalities. Although common in the pediatric population isolated orbital roof fractures can also occasionally occur in an adult fig 13.

Orbital blowout fractures occur when there is a fracture of one of the walls of orbit but the orbital rim remains intact. Very rarely the orbital roof will fracture without displacement of fractures fragments resulting in the non displaced orbital roof fracture.
