Orbital Roof Fracture Definition

When they do happen they may be associated with intracranial hemorrhages traumatic optic neuropathy and csf leakage into the orbit.

Orbital roof fracture definition.

Orbital blowout fractures are usually the result of a direct blow to the orbit which causes a sudden increase in intraorbital pressure. 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 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. Orbital roof fracture icd 801 01 etiology.

Orbital fracture is a breakage in the bone in the eye socket which can involve the rim the floor or even both. An orbital fracture is when there is a break in one of the bones surrounding the eyeball called the orbit or eye socket. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. Isolated orbital roof fractures in adults are uncommon comprising 12 19 of all orbital wall fractures.

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. 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. Decompression then occurs by fracture of one or more of the bounding walls of the orbit. Clinical diagnosis is based on meticulous examination of the eye including patient vision and palpation of the orbital aperture.

Fractures of the orbital roof typically require a significant amount of force. This frequently causes downward and forward displacement of the globe. Fractures to the inferior.
