Orbit - Floor Reconstruction

Considerations

• • Approaches

    • Lower eyelid

      • Trans-conjunctival 

      • Trans-cutaneous  

    • Endoscopic, including trans-nasal and trans-antral 

    • 2007: Endoscopic versus external repair of orbital blowout fractures

    • 2009: Endoscopic transantral repair of orbital floor fractures

      • • Excellent article with operative technique and illustrations 

      • 2012: Endoscopic transnasal approach to repair the orbital floor (poster) 

    • Midface exposure 

      • Maxillary vestibular

      • Midface degloving 

  • Existing laceration 

    • Combined

Pearls & Pitfalls 

• • Pearls

    • Always perform a pre and post repair forced duction test in both lateral and vertical planes 

    • Always protect the cornea
