This technical note describes the usage of object matching to virtually compare different modes reconstruction in orbital trauma and display results surgeon patient pre-operatively via mixed reality devices for enhanced surgical decision making immersive education. A case an floor fracture is presented which surface volume were implemented utilizing pre-fabricated titanium meshes versus patient-specific implants. The could be visualized by further enhance decision-making. data sets demonstrated education shared making. advantages new technologies are discussed view possibilities improved informed consent processes, as well ways teaching medical trainees.

The aim of this study is to investigate the feasibility perpendicular plate ethmoid as material for reconstruction medial orbital wall. main outcome measurement was preoperative and postoperative volume. authors performed a including 17 patients who have isolated wall fracture (blow-out fracture). All were fixed defect using autologous under endonasal approach. compared volume difference (unaffected orbit, affected orbit) all patients, observed improvement diplopia or ocular motility disorders after operation. surgeries successful with no severe ophthalmic complications. Statistically significant differences found between tissue volumes orbit. There statistically contralateral unaffected orbit reconstruction. And computed tomography showed implant in place there rectus incarceration. Autologous proved be safe effective approach cost-effectivence, low complication rate, high biocompatibility, minimally invasion.

Background: During blow-out fracture surgery, restoration of the orbital volume and rigid implant fixation are essential. The migration an is a concern most surgeons. purpose this study was to introduce simple idea molding fixing implant. Methods: In tongue-in-groove method, incision about 2 mm made on edge it bent form slot. A hole in center for fitting bone hook, firmly fit into remaining intact bone. Before after computed tomography (CT) used evaluate changes location Statistically significant confirmed postoperative CT. Results: Compared with unaffected volume, affected increased from 87.06 ± 7.92% before surgery 96.14 6.11% (p < 0.001). There one case during follow-up. However, degree movement not severe, there were no events follow-up period. Conclusions: technique offers advantages, such as easy implant, minimal trauma surrounding tissues. addition, method being learn, requiring little time trimming relatively low cost. Therefore, can be options fixation.
