“…The RP technique involves (1) CT scanning, (2) CT data processing and virtual 3D model creation, and (3) model production by RP, all of which takes approximately 120 minutes [ 2 ]. Virtual 3D modeling can determine the location and size of the orbital cavity defects and the anatomy of individual patients, and preoperative virtual surgical planning may enable greater accuracy in reconstructed contour [ 10 20 ]. Three-dimensional measurements are used to determine the variations in the orbital cavity volume, predict potential enophthalmos, even at the early stage of injury, and help determine the operability.…”

BackgroundRestoring the orbital cavity in large blow out fractures is a challenge for surgeons due to the anatomical complexity. This study evaluated the clinical outcomes and orbital volume after orbital wall fracture repair using a rapid prototyping (RP) technique and intraoperative navigation system.MethodsThis prospective study was conducted on the medical records and radiology records of 12 patients who had undergone a unilateral blow out fracture reconstruction using a RP technique and an intraoperative navigation system from November 2014 to March 2015. The surgical results were assessed by an ophthalmic examination and a comparison of the preoperative and postoperative orbital volume ratio (OVR) values.ResultsAll patients had a successful treatment outcome without complications. Volumetric analysis revealed a significant decrease in the mean OVR from 1.0952±0.0662 (ranging from 0.9917 to 1.2509) preoperatively to 0.9942±0.0427 (ranging from 0.9394 to 1.0680) postoperatively.ConclusionThe application of a RP technique for the repair of orbital wall fractures is a useful tool that may help improve the clinical outcomes by understanding the individual anatomy, determining the operability, and restoring the orbital cavity volume through optimal implant positioning along with an intraoperative navigation system.

“…It allows a surgeon to visualize bony changes, to perform measurements to assure adequate positioning of the bony segments, and to accurately design custom-made facial implants. [19][20][21] Also, and possibly most important, the patient was made part of this planning session and could visualize the improvements and limitations preoperatively.…”

Virtual surgical planning (VSP) has recently been introduced in craniomaxillofacial surgery with the goal of improving efficiency and precision for complex surgical operations. Among many indications, VSP can also be applied for the treatment of congenital and acquired craniofacial defects, including orbital fractures. VSP permits the surgeon to visualize the complex anatomy of craniofacial region, showing the relationship between bone and neurovascular structures. It can be used to design and print using three-dimensional (3D) printing technology and customized surgical models. Additionally, intraoperative navigation may be useful as an aid in performing the surgery. Navigation is useful for both the surgical dissection as well as to confirm the placement of the implant. Navigation has been found to be especially useful for orbit and sinus surgery. The present paper reports a case describing the use of VSP and computerized navigation for the reconstruction of a large orbital floor defect with a custom implant.
