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.

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. 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. With blow out fractures of the orbital floor ct scanning can directly depict the degree of enophthalmos if any.

Hemorrhage partially fills the left maxillary sinus. An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall typically resulting from impact of a blunt object larger than the orbital aperture or eye socket most commonly the inferior orbital wall i e. Clinical recommendations for repair of isolated orbital floor fractures. Large fractures involving at least half of the orbital floor particularly when associated with large medial wall fractures determined by ct.

Left orbital floor fracture. 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. There are three main types of orbital fractures that we see. Different types of orbital fractures can occur since the rim of the socket is made of fairly thick bones while the floor and nasal side of the socket is paper thin in many places.

The blowout fracture is the most common type of orbital fracture and is usually the result of trauma. Thin cut coronal reconstructions are actually preferred to. A blowout fracture of the orbital floor is defined as a fracture of the orbital floor in which the inferior orbital rim is intact. Orbital fractures of this size have a high incidence of subsequent significant enophthalmos.

1 0 1 5mm axial ct scans of the orbit with coronal reconstruction. This is reflected in the demographics. Orbital floor fracture also known as blowout fracture of the orbit eye socket. No evidence of rectus muscle entrapment retrobulbar hemorrhage or proptosis.

It is more prevalent in young men. This fracture can also affect the muscles and nerves around the eye keeping it from moving properly and feeling normal. Bilateral frontal intraparenchymal hemorrhages. Orbital floor fracture also known as blowout fracture of the orbit.

Left orbital floor fracture is depressed by 3 5 millimeters. Orbital blowout fractures are usually the result of a direct blow to the orbit which causes a sudden increase in intraorbital pressure.
