The most important landmark of the floor is the inferior orbital.
Floor of right orbit.
It is formed by three bones.
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.
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.
The globe usually does not rupture and the resultant force is transmitted throughout the orbit causing a fracture of the orbital floor.
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.
A fracture of the lateral maxillary sinus wall also is.
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.
The anatomy of the orbital floor predisposes it to fracture.
An example of a patient presenting with a right orbital floor blowout fracture.
Orbital blowout fracture or indirect orbital floor fracture.
Orbital floor fractures may result when a blunt object which is of equal or greater diameter than the orbital aperture strikes the eye.
The cyst lining had proliferated to fill up the entire sinus cavity.
The floor is separated from the lateral wall by inferior orbital fissure which connects the orbit to pterygopalatine and infratemporal fossa.
There was also the previously diagnosed impacted tooth in the floor of the maxillary sinus.
This showed an additional finding of an impacted tooth in the floor of the right orbit.
Ct scan demonstrates common findings of a blow out fracture with evidence of a depressed right orbital floor bottom.
A blowout fracture is a break in the floor or inner wall of the orbit or eye socket.
This is a fracture of the paper thin floor of the eye socket with the bony rim surrounding the eye remaining intact.

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 orbital surface of the maxilla makes up most of it while small portions of the zygomatic and palatine bones make up the rest.

Maxilla zygomatic bone and palatine bone.
