“…Raith et al 29 described a custom algorithm for planning mandibular reconstructions that approximates the fibula and mandibular resection with curves, and then matches the curves to create the reconstruction. Their algorithm was recently evaluated ex vivo by Modabber et al 30 Nakao et al 31 described a significantly more complex algorithm that accounts for the 3D shape of the mandible rather than a curve approximation and evaluate it ex‐vivo. However, these workflows have not been evaluated clinically.…”

Background: Virtual surgical planning (VSP), via commercial services or developed in-house, has been applied to facilitate head and neck reconstruction. We evaluate a custom, automated planning software. Methods: Prospectively, VSP of 25 consecutive patients undergoing segmental mandibular reconstruction was performed. Postoperative CT was used to assess structural accuracy of VSP. Operative time, length of stay, and complication rate of the prospective cohort were compared with those of 25 consecutive retrospective historical cases. Results: The deviations between the plan and execution in mandibular width, projection, and volumetric overlap were 2.32 ± 3.91, 2.39 ± 1.72, and 0.59 ± 0.51 mm respectively. Compared with historical data, there was a significant reduction in operative time and length of stay, and no significant difference in complication rates. Conclusion: This is the largest prospective series evaluating an in-house VSP workflow for mandibular reconstruction and the first clinical evaluation of an automated planning platform.

“…Previously published related works tried to consider the whole surfaces of both transplant and recipient bones . While that is a comprehensive approach it is also complicated because the curvatures of the anatomical surfaces in space are difficult to comprehend and it thus seems to be challenging to implement these algorithms in clinical routine and use their (semi‐)automated proposals for mandibular reconstructions.…”

“…The fundamental difference of the present approach from published works with similar intentions is that the three‐dimensional bone surface geometries are simplified to curves that follow certain anatomical features. The advantage of using these curves to define the relevant contour of the target shape is that it reduces the overwhelmingly complex task of mandibular reconstruction to a manageable procedure.…”

“…In this situation, grinding the bones to the desired shape is necessary. Since the mandible may be very fragile and unstable after surgery, a specific plate designed for the patient is needed to fix the bones [25]. In brief, maxillofacial surgery includes three essential operations: open reduction, osteotomy, and plate fixation.…”

Due to the complexity of the maxillofacial surgery, the novice should be sufficiently trained before one is qualified to carry on the surgery. To reduce the training costs and improve the training efficiency, a virtual mandible surgical system with haptic feedback is proposed. This surgical simulation system offers users the haptic feedback while simulating maxillofacial surgery. An integrated model is introduced to optimize the system simulation process, which includes force output to a six-degree-of-freedom haptic device. Based on the anatomy structure of the bone tissue, a two-layer mechanism model is designed to balance the requirement of real-time response and the force feedback accuracy. Collision detection, force rendering, and grinding function are studied to simulate some essential operations: open reduction, osteotomy, and palate fixation. The proposed simulation platform can assist in the training and planning of these oral and maxillofacial surgeries. The fast response feature enables surgeons to design a patient-specific guide plate in real-time. Ten stomatology surgeons evaluated this surgical simulation system from the following four indexes: the level of immersion, user-friendliness, stability, and the effect of surgical training. The evaluation score is eight out of ten.
