. Orbital floor fractures OFF with entrapment require prompt clinical and radiographic recognition for timely surgical correction. Received March 27 2008. Appropriate timing is based on the clinical exam and imaging.

An orbital roof blow-out fracture may warrant a neurosurgery consultation for the risks of cerebrospinal fluid leak and brain injury. The indications for surgical repair of orbital fractures have been controversial. Hemorrhage in the right maxillary and ethmoid sinus and a large retention cyst of the maxillary sinus on the left side is.

Correct CT radiographic interpretation of entrapped fractures can be subtle and thus missed. The orbital floor andor medial wall are most commonly involved. The author has no financial relationships to.

An orbital floor blow-out fracture with frank enophthalmos appears as a bulbous soft-tissue mass extending from the expected level of the orbital floor into the maxillary antrum beneath. It involves the lens and orbital fat and is associated with a right maxillary sinus hemorrhage. Blow-out fracture in the right orbital medial wall and nasal side floor with pronounced inferonasal orbital fat entrapment and partially entrapped medial rectus muscleLarge emphysema in eyelids and a few foci of air bubbles in the postseptal orbital cavity are noted.

Imaging of Orbital Trauma. The eyelids and orbital emphysema are not always correlated well with the severity of bone displacement in orbital blow-out fractures. Facial fractures can be identified by tracing the McGrigor-Campbell lines and Dolan lines.

1 medial orbital wall with the thin weak lamina papyracea of the ethmoid bone Fig. Fracture of the orbital floor can disrupt the. No evidence of rectus muscle entrapment retrobulbar hemorrhage or proptosis.

Orbital floor implant position is best assessed in the. These fractures do not involve. Approximating an identical slope at the time of repair of an orbital floor fracture is critical to restoring the premorbid orbital volume thus preventing enophthalmos.

Left orbital floor fracture. Enophthalmos can occur with large fragment blow-out fractures and its extent is best appreciated and repaired in delayed fashion after the edema has resolved. Gross tissue hemorrhage surrounds the right orbit with blood also within the partly collapsed right globe.

Revision requested June 6 and received June 29. 1141 Blowout Fracture. Other secondary signs of facial fracture include opacification of adjacent air spaces which may fill with blood if a wall of that air space is fractured.

Orbital floor fracture repair might be indicated in this setting for small or medium sized defects. 1 From the Department of Diagnostic Radiology Yale University School of Medicine 333 Cedar St Room CB 30 New Haven CT 06510. Revision requested June 6 and received June 29.

Orbital floor fractures result from sudden increased intraorbital pressure caused by the eyeballs transmission of the force of a blow. Imaging of Orbital Trauma. It is seen in children and young adults due to the elasticity of the orbital floor.

An orbital blowout fracture refers to two kinds of fractures that can occur through the weakest portions of the orbit. Indirect findings include asymmetrical hemorrhage-related opacification of a paranasal sinus adjacent to a particular orbital surface. Signs of orbital fracture typically include peri-ortbital bruising and subconjunctival hemorrhage.

Isolated orbital fractures most commonly involve the weak medial orbital wall or floor sparing the orbital rim lead to enlargement of the orbit and are known as blow-out fractures Fig. Common mechanisms include blunt trauma mainly from assault and motor vehicle accident. Contrary to popular belief the orbital floor is not horizontal in orientation but rather slopes upward toward its posterior aspect because of the conical shape of the orbit.

Received March 27 2008. Inferior orbital fractures can be caused by direct facial trauma. Bilateral frontal intraparenchymal hemorrhages.

Orbital floor fracture radiology. Superior rim and orbital roof fractures occasionally occur particularly if the adjacent frontal sinus is well developed. However common radiological findings of orbital blowout fractures include comminutedunhinged hinged and linear fractures.

There is marked architectural distortion of the globe. Fractures of the orbital floor and the medial orbital wall blowout fractures are common midface injuries. Hemorrhage partially fills the left maxillary sinus.

Large fracture 50 of orbital floor on CT scan indicates that enophthalmos is likely to occur. Orbital fractures are common occurring in 10-25 of all cases of facial fracture 1. These fractures are usually located in the orbital floor medial to the infraorbital nerve and in the medial orbital wall.

Orbital emphysema is one of the indications for surgical repair of the fracture. A blowout Fracture of the orbital floor is defined as a fracture of the orbital floor in which the inferior orbital rim is intact. 1 From the Department of Diagnostic Radiology Yale University School of Medicine 333 Cedar St Room CB 30 New Haven CT 06510.

Left orbital floor fracture is depressed by 35 millimeters. Floor fractures without rim involvement which are referred to clinically as. And 2 orbital floor with the linear weak infraorbital canal Fig.

Blow-out fractures are so named because of the tendency for soft tissue to herniate out of the orbit. We reviewed the clinical radiographic and intraoperative findings of 45 cas. A retrospective series of orbital axial and coronal computed tomography scans from 24 orbital floor fractures was studied to define the anatomic location of the fracture.

It is estimated that about 10 of all facial fractures are isolated orbital wall fractures the majority of these being the orbital floor and that 30-40 of all facial fractures involve the orbit. Orbital fat is frequently herniated in the paranasal sinus or incarcerated at the fracture site. The orbital MDCT is the imaging modality of choice for blow-out fracture diagnosis and evaluation for complications such as inferior rectus muscle entrapment.

There is a right orbital floor blowout fracture entrapping the inferior rectus. The inferior orbital wall is most commonly affected by fracture 2. The size of the orbital floor fracture is often.

There is a right orbital floor blowout fracture entrapping the inferior rectus.
