Abstract
External impact to the orbit may cause a blowout or zygomatico-maxillary fractures.
Diagnosis and treatment of orbital wall fractures are based on both physical examination
and computed tomography scan of the orbit. Injuries of the orbit often require a reconstruction
of its orbital walls. Using computer-assisted techniques, anatomically preformed orbital
implants, and intraoperative imaging offers precise and predictable results of orbital
reconstructions. Secondary reconstruction of the orbital cavity is challenging due
to fractures healed in malposition, defects, scarring, and lack of anatomic landmarks,
and should be avoided by precise primary reconstruction. The development of preformed
orbital implants based on topographical analysis of the orbital cavity was a milestone
for the improvement of primary orbital reconstruction.
