Learning objectives
the main purpose of our poster is
To help radiologist undertand mecanisms of orbital trauma
To illustrate differentes types of fractures as well as their acute and chronic complications with cases from our facility
Background
Facial trauma constitutes a public health problem. Due to anatomical proximity, craniofacial trauma involves orbital injury in up to 15%.It associated with significant morbidity, including permanent visual loss.
Clinical assessment may be limited by edema and concomitant injuries, therefore imaging has a primary role in delineating the trauma pattern and extent of injury.
Relevant anatomy
Theorbit is arelatively small and anatomically complex space that contains many critical structures. An understanding of ocular anatomy is critical to appreciating how trauma can affect distinct parts of the...
Findings and procedure details
Certain orbital fractures occur with sufficient regularity to allow a classification into types. This classification has practical value, is that a particular mechanism tends to produce a type of fracture.
Orbital blowout fractures occur when one of the orbital walls is fractured but the orbital rim remains intact. It is caused by a direct blow to the central orbit from an object larger than the orbital rim. There is an increase of pressure and fractures occur through the weakest portions (lamina papyracea and orbital floor)...
Conclusion
CT examinations should play a major role in the evaluation of the intraorbital contents in patients with orbital trauma.
