Coronal ct scan soft tissue window showing right orbital floor fracture vertical elongation of right orbit reduction in size of right maxillary sinus and soft tissue swelling of the right.
Floor of right orbit.
Coronal ct scan soft tissue window showing right orbital floor fracture vertical elongation of right orbit reduction in size of right maxillary sinus and soft tissue swelling of the right maxillary sinus mucosa.
Bruising and limited eye movements secondary to swelling are common clinical presentations top.
This is a fracture of the paper thin floor of the eye socket with the bony rim surrounding the eye remaining intact.
Ct scan demonstrates common findings of a blow out fracture with evidence of a depressed right orbital floor bottom.
The floor of the eye socket ruptures or cracks resulting in a small hole in the eye socket s floor which can trap some parts of the eye muscles and its surrounding.
It is formed by three bones.
The anatomy of the orbital floor predisposes it to fracture.
Coronal ct scan showing orbital floor fracture posterior to the globe.
The floor is separated from the lateral wall by inferior orbital fissure which connects the orbit to pterygopalatine and infratemporal fossa.
The orbital surface of the maxilla makes up most of it while small portions of the zygomatic and palatine bones make up the rest.
This showed an additional finding of an impacted tooth in the floor of the right orbit.
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.
Maxilla zygomatic bone and palatine bone.
An example of a patient presenting with a right orbital floor blowout fracture.
The most important landmark of the floor is the inferior orbital.
Orbital floor fractures may result when a blunt object which is of equal or greater diameter than the orbital aperture strikes the eye.
There was also the previously diagnosed impacted tooth in the floor of the maxillary sinus.
The medial wall is formed primarily by the orbital plate of ethmoid as well as contributions from the frontal process of maxilla the lacrimal bone and a small part of the body of the sphenoid.
The cyst lining had proliferated to fill up the entire sinus cavity.
A blowout fracture is a break in the floor or inner wall of the orbit or eye socket.
Fractures of the orbital floor are common.
A fracture of the lateral maxillary sinus wall also is.
The floor or inferior wall separates the orbit and the maxillary sinus.
A biopsy of the lesion returned with the diagnosis of maxillary sinus dentigerous cyst.
The globe usually does not rupture and the resultant force is transmitted throughout the orbit causing a fracture of the orbital floor.
