To review the normal anatomy of the orbit,
the zygoma complex and the key anatomical landmarks in the diagnosis of orbital fractures. To describe basic radiological findings of orbital fractures both preoperative and postoperatively in CT Scans,
including possible complications. To describe basic 3D postprocessing tools for pre and postoperative orbital volumen assessment including CAD-CAM custom-made orbital titanium mesh design.
Fractures of the facial skeleton are associated with cosmetical and functional deformities if left untreated or poorly managed.
Aproximately 10-to 30% of them involve the orbit. Trained Maxillofacial Surgeons have historically anticipated facial fracture patterns and associated organ system injuries by understanding the mechanism of injury.
The same knowledge applies to the ER Radiologist.
Knowing in detail the pattern of fractures,
the key anatomic structures and the basic guidelines of...
Findings and procedure details
ANATOMY The orbit is a unique structure that has the primary purpose of housing and protecting the globe.
By age 5 years,
orbital growth is 85% complete; growth is finalized between 7 years of age and puberty. The orbit is a four- sided pyramid with its apex at the optic foramen; anteriorly its base is formed by the orbital rim.
The orbital rim consists of dense cortical bone that protects the orbital contents from direct trauma. Seven bones contribute to the formation of the orbit:...
Radiologist play an important role in the diagnosis of orbital fractures.
An accurate report may help the clinician determine the severity of the lesion.
the radiologist knowledge of volumetric imaging 3D Tools can play a decisive role in presurgical planning (including the design of custom-made reconstruction plates d with Cad-Cam systems) and postsurgical evaluation.
