Intraoperative stereotactic navigation for reconstruction in zygomatic-orbital trauma

Reconstruction of the maxillofacial skeleton after traumatic injury is not always straightforward because of its three dimensional complex anatomy and aesthetic significance. In case of zygomatic-orbital injury induced by trauma resulting in enophthalmos, the patient is affected on both function and cosmesis. To prevent diplopia or conspicuous asymmetry, exact correction of the orbital symmetry is required. The aim of this case report is to demonstrate the use of an intraoperative image guided navigation system for identification of adequate reconstruction of the orbital floor and orbital symmetry in zygomatic-orbital fracture. Navigation-guided open reduction of a zygomatic-orbital complex fractures with orbital floor reconstruction can be regarded as a valuable treatment option for this potentially complicated procedure. This case demonstrated the use of the non-ionizing, noncontact, navigation system in intraoperative procedure and clinical monitoring to identify the correct position and symmetry in complex orbital floor reconstruction.
