Orbital Floor Fracture On Ct

These findings were confirmed on ct which also demonstrated multiple small foci of brain hemorrhagic contusions.

Orbital floor fracture on ct. Decompression then occurs by fracture of one or more of the bounding walls of the orbit. Ophthalmologists most often get involved in pure orbital fractures with an intact orbital rim and without other facial bone fracture. A fracture is a broken bone in the eye socket involving the rim the floor or both. Radiographs demonstrating a left orbit floor fracture and associated opacification of the maxillary sinus hemosinus.

A le fort iii fracture or craniofacial dysjunction denotes a complete separation of the midface or facial bones from the cranium. The bony eye socket structure is called the orbit. Orbital floor fractures can present as blow out fractures or in combination with a zygoma or le fort fractures. 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.

Any type of blunt force facial trauma can damage the orbital bones and cause an orbital fracture. Thin cut coronal reconstructions are actually preferred to direct coronal images as they avoid artifact from dental amalgam. The floor is likely to collapse because the bones of the roof and lateral walls are robust. This fracture traverses the zygomaticofrontal suture continues.

When we refer to an orbital floor fracture in this text a blow out fracture is meant. 33 are associated with ocular trauma. Depending on the location and mechanism intracranial thoracic and abdominal injuries may be associated. Most commonly the inferior orbital wall i e.

Fracture of inferior or medial orbital walls with out fracture of orbital ridge. Patients suspected of suffering an orbital floor fracture should undergo thin cut 1 0 1 5mm axial ct scans of the orbit with coronal reconstruction. Orbital fractures commonly occurby blunt periocular trauma. 7 public playlist includes this case.

Direct fractures of the orbital floor can extend from fractures of the inferior orbital rim. A blow out fracture pure is a fracture of internal orbital walls without fractures of orbital rims. Indications for repair of the orbital floor in these cases are the same as those for indirect blowout fractures. Adipose tissue inferior rectus or inferior oblique can entrap within maxillary or ethmoid sinus.
