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.
