Orbital Roof Fracture Definition

Fractures of the orbital roof typically require a significant amount of force.

Orbital roof fracture definition.

Usually this kind of injury is caused by blunt force trauma when something hits the eye very hard. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. Decompression then occurs by fracture of one or more of the bounding walls of the orbit. The isolated orbital roof blow up fracture also known as blow out fracture is defined as superior displacement of the fracture fragment into the anterior cranial fossa without involvement of.

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. The isolated orbital roof blow up fracture also known as blow out fracture is defined as superior displacement of the fracture fragment into the anterior cranial fossa without involvement of the supraorbital rim with possible herniation of orbital contents outside of the orbital confines 3. This frequently causes downward and forward displacement of the globe. An orbital fracture is when there is a break in one of the bones surrounding the eyeball called the orbit or eye socket.

The inferior wall or orbital floor is formed by the upper jawbone maxilla part of the cheek bone zygomatic and a small part of the hard palate palatine bone. Orbital fracture is a breakage in the bone in the eye socket which can involve the rim the floor or even both. Clinical diagnosis is based on meticulous examination of the eye including patient vision and palpation of the orbital aperture. Isolated orbital roof fractures in adults are uncommon comprising 12 19 of all orbital wall fractures.

Orbital blowout fractures are usually the result of a direct blow to the orbit which causes a sudden increase in intraorbital pressure. When they do happen they may be associated with intracranial hemorrhages traumatic optic neuropathy and csf leakage into the orbit. Orbital roof fracture icd 801 01 etiology.
