It is estimated that approximately 25% of facial trauma involves an orbital fracture. Surgical repair of orbital fractures is only required when restoration of orbital anatomy, volume, or function is necessary. A variety of techniques have been described to reconstruct orbital fractures, and all are associated with low morbidity. However, even in the hands of an experienced surgeon, complications such as orbital dystopia, extraocular muscle injury, diplopia, and blindness still occur. In the current age of advancing technology, surgeons are constantly pioneering new modalities that improve surgical accuracy and reduce perioperative morbidity. Computed tomography (CT) image-guided navigation is one technology that may prove useful in maxillofacial surgery. It allows a surgeon to utilize realtime intraoperative localization of skeletal landmarks based on a preoperative CT scan. Initially introduced in the late 1980 s, CT imaged-guided navigation allowed neurosurgeons the ability to better locate intracranial tumors. Today, CT image-guided navigation is used in most intracranial neurosurgical procedures, and its use has expanded to several surgical subspecialties. Orbital reconstruction is highly reliant on anatomical accuracy and localization. As a result, preoperative planning and intraoperative anatomical identification is critical. Planning for orbital reconstruction is routinely based on preoperative CT scans. The ability to use preoperative imaging at the time of surgery allows precise anatomical localization. The authors hypothesize that the use of CT image-guided navigation in orbit fracture reconstruction is feasible and improves surgical accuracy. This modality may prove to reduce complications and morbidity in many complex maxillofacial procedures in the future.
