The floor or inferior wall separates the orbit and the maxillary sinus.
Floor of right orbit.
Orbital blowout fracture or indirect orbital floor fracture.
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.
Maxilla zygomatic bone and palatine bone.
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.
Fractures of the orbital floor are common.
The globe usually does not rupture and the resultant force is transmitted throughout the orbit causing a fracture of the orbital floor.
Getting hit with a baseball or a fist often causes a blowout fracture.
An example of a patient presenting with a right orbital floor blowout fracture.
The floor is separated from the lateral wall by inferior orbital fissure which connects the orbit to pterygopalatine and infratemporal fossa.
A crack in the very thin bone that makes up these walls can pinch muscles and other structures around the eye keeping the eyeball from moving properly.
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.
Ct scan demonstrates common findings of a blow out fracture with evidence of a depressed right orbital floor bottom.
It is formed by three bones.
A biopsy of the lesion returned with the diagnosis of maxillary sinus dentigerous cyst.
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.
This showed an additional finding of an impacted tooth in the floor of the right orbit.
The orbital surface of the maxilla makes up most of it while small portions of the zygomatic and palatine bones make up the rest.
The anatomy of the orbital floor predisposes it to fracture.
A blowout fracture is a break in the floor or inner wall of the orbit or eye socket.
A fracture of the lateral maxillary sinus wall also is.
Coronal ct scan showing orbital floor fracture posterior to the globe.
The cyst lining had proliferated to fill up the entire sinus cavity.
There was also the previously diagnosed impacted tooth in the floor of the maxillary sinus.
Orbital floor fractures may result when a blunt object which is of equal or greater diameter than the orbital aperture strikes the eye.
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.
