Ct Of Orbital Floor Fracture

Direct visualization of extraocular muscles aids in determining if the inferior rectus muscle is hooked or entrapped in an orbital floor fracture if a similar injury to the medial rectus muscle against a medial wall fracture is.

Ct of orbital floor fracture.

Bilateral frontal intraparenchymal hemorrhages. This is reflected in the demographics. Orbital floor fracture also known as blowout fracture of the orbit eye socket. Thin cut coronal reconstructions are actually preferred to.

Hemorrhage partially fills the left maxillary sinus. Orbital floor fracture also known as blowout fracture of the orbit. Left orbital floor fracture is depressed by 3 5 millimeters. 1 0 1 5mm axial ct scans of the orbit with coronal reconstruction.

A blowout fracture of the orbital floor is defined as a fracture of the orbital floor in which the inferior orbital rim is intact. These fractures occur in the bony outer edges of the eye socket. Getting hit with a baseball or a fist often causes a orbital blowout fracture. An orbital computed tomography the gold standard in trauma ct with contiguous thin axial and coronal sections should be ordered to confirm the diagnosis and plan for treatment see figure 1a.

No evidence of rectus muscle entrapment retrobulbar hemorrhage or proptosis. Large fractures involving at least half of the orbital floor particularly when associated with large medial wall fractures determined by ct. With blow out fractures of the orbital floor ct scanning can directly depict the degree of enophthalmos if any. The floor is likely to collapse because the bones of the roof and lateral walls are robust.

This is when a blow or trauma to the orbital rim pushes the bones back causing the bones of the eye socket floor buckle to downward. It is more prevalent in young men. The blowout fracture is the most common type of orbital fracture and is usually the result of trauma. Orbital blowout fractures are usually the result of a direct blow to the orbit which causes a sudden increase in intraorbital pressure.

Left orbital floor fracture. Clinical recommendations for repair of isolated orbital floor fractures. This fracture can also affect the muscles and nerves around the eye keeping it from moving properly and feeling normal. Orbital floor fractures may result when a blunt object which is of equal or greater diameter than the orbital aperture strikes the eye or on the cheek 1.

Orbital fractures of this size have a high incidence of subsequent significant enophthalmos. There are three main types of orbital fractures that we see.
