Orbital Reconstruction and Orbital Volume

Abstract

Orbital fractures are common presentation in the head and neck trauma centers. They can result in functional and esthetic problems. The primary goal in the repair of the orbital fractures is to restore the orbital shape and volume, free the incarcerated or prolapsed orbital tissue from the fracture defect, and span the bony defect with reconstructive implant material. Titanium mesh was very appropriate reconstructive material for anatomic reconstruction. The orbit has a special complex geometry which makes perfect anatomic reconstruction very difficult. The manual process of fitting and adapting the implant within the orbit is time consuming and operator dependent. The advanced techniques in maxillofacial imaging and computer assisted techniques resulted in improvement in the implant design for management of orbital fractures. The current study was made to review the accuracy of adapting the titanium mesh using STL model versus conventional technique for restoring the orbital volume in management of orbital floor fracture.
