What is the most common location for orbital fractures?
What is the most common location for orbital fractures?
Anatomy and Mechanism of injury. Blowout fractures of the orbit most frequently affect the middle third of the orbit where the orbital walls are the thinnest. Inferior blowout fractures involving the floor of the orbit (maxillary sinus roof) are the most common followed by medial wall blowout fractures.
What is a superior orbital fracture?
Disease Entity. Fractures of the roof of the orbit are typically associated with trauma to the forehead/frontal bone are are often extensions of superior orbital rim fractures. Isolated non-displaced orbital roof fractures most commonly seen in children and rarely require surgical intervention.
What is orbital floor fracture?
Orbital floor fracture, also known as “blowout” fracture of the orbit. A “blowout Fracture of the orbital floor is defined as a fracture of the orbital floor in which the inferior orbital rim is intact.
What is an orbital fracture of the eye?
An orbital fracture occurs when one or more of the bones around the eyeball break, often caused by a hard blow to the face. To diagnose a fracture, ophthalmologists examine the eye and surrounding area. X-ray and computed tomography scans may also be taken.
Where is the orbital floor located?
maxillary sinus
The orbital floor, which forms the roof of the maxillary sinus, slopes upward toward the apex of the pyramid, which lies roughly 44 to 50 mm posterior to the orbital entrance [3,4].
Which bone of the orbit is most likely to fracture with blunt orbital trauma?
The orbital floor, the maxillary bone, is the most common orbital fracture. These floor-fractures are quite common.
Which part of orbit is weakest?
orbital floor
The weakest portion of the orbit consists of the thin orbital floor (maxilla) and the lamina papyracea (ethmoid bone) medially and inferiorly.
How deep is an eye socket?
This distance varied from 4.4 to 5.7 cm in males (mean 5.024, SD 0.272) and from 4.5 to 5.5 cm in females (mean 4.9, SD 0.204).
