Floor Of Right Orbit

The floor or inferior wall separates the orbit and the maxillary sinus.

Floor of right orbit.

There was also the previously diagnosed impacted tooth in the floor of the maxillary sinus. A fracture of the lateral maxillary sinus wall also is. A blowout fracture is a break in the floor or inner wall of the orbit or eye socket. Coronal ct scan showing orbital floor fracture posterior to the globe.

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. Maxilla zygomatic bone and palatine bone. The anatomy of the orbital floor predisposes it to fracture. Getting hit with a baseball or a fist often causes a blowout fracture.

This is a fracture of the paper thin floor of the eye socket with the bony rim surrounding the eye remaining intact. 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 globe usually does not rupture and the resultant force is transmitted throughout the orbit causing a fracture of the orbital floor.

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. Fractures of the orbital floor are common. The most important landmark of the floor is the inferior orbital.

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. 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.

It is formed by three bones. An example of a patient presenting with a right orbital floor blowout fracture. 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.

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.
