The goal of the treatment of orbital fractures is to reconstruct the three-dimensional shape of the orbital walls to restore the orbital volume and eye function. Enophthalmos and diplopía caused by inappropriate orbital wall anatomy reconstruction after trauma, remain still a sequel to these fractures. The objectives of this paper are to describe the technique of virtual planning and intraoperative navigation in the treatment of floor and medial wall fractures of the orbit as a useful tool in the treatment of these fractures. We have applied the technique of virtual planning and navigation for the treatment of patients with fractures of floor and/or medial orbital wall. The virtual correction of the fractured orbit is performed using the mirror image of the healthy side superimposed on the fractured side. Preoperative computer planning also allows importing the object 'premolded mesh" to the plan to determine its appropriateness, in shape and size, to treat the fracture. Intraoperative navigation allows a safe and proper dissection ("first" navigation) of the orbital contents and confirmed the proper reconstruction of the orbital walls ("second" navigation). Navigation allows a safe dissection of the orbital contents and a verification of the accuracy of the position of the mesh. Computer planning, virtual surgery and intraoperative navigation provide precise guidance and safety for orbital reconstruction.
