Study Notes
Anatomy of the Orbit
- The orbits are bony cavities that house and protect the eyes.
- Each orbit is made up of seven craniofacial bones:
- Frontal
- Lacrimal
- Ethmoid
- Maxilla
- Zygomatic
- Sphenoid
- Palatine
Orbital Fractures
- Orbital fractures can lead to serious complications affecting the eyes.
- Two primary types of orbital fractures are:
- Floor fractures: Injuries affecting the bottom part of the orbit.
- Orbital blowouts: Occur when force causes the thin bones in the orbit to fracture, often resulting in herniation of orbital contents.
