“…In the second patient (unilateral LeFort II fracture with contralateral zygomatico-maxillary complex fracture), intermaxillary elastics were used for guiding the occlusion. Post-trauma occlusal discrepancy in this patient could be attributed to haematoma, swelling and inhibition of muscular movement due to the fractured zygomatico-maxillary complex [17]. Occlusal discrepancy in this case could also be attributed to the presence of comminution of all the fracture sites [18].…”

Introduction Trauma is steadily increasing in the modern world and thus becoming a major public problem. Maxillofacial injuries constitute a substantial proportion of cases of trauma and occur in a variety of situations like road traffic accidents, interpersonal violence, falls or as a result of contact sports. The aim of this prospective study was to evaluate the efficacy of titanium mesh for osteosynthesis of maxillofacial fractures. Materials and Methods Fifteen patients of maxillofacial fractures who were treated with titanium mesh were included in this prospective study. The patients were evaluated preoperatively, intraoperatively and postoperatively at 7th day, 3rd week, 6th week and 12th week. ResultsThe mean age of fifteen patients was 31.3 years with a male:female ratio of 14:1. The most common mode of injury was road traffic accident (86.6%). The mean time interval between injury and surgical procedure was found to be 7.6 days. The majority of fracture sites (88%) were comminuted. 93.3% of the patients achieved good occlusion by 12th week postoperatively. Postoperative complications included residual hypoaesthesia in four patients and wound dehiscence in one patient. Conclusion We conclude that titanium mesh is a versatile option for maxillofacial fractures. It provided good stabilization especially in comminuted fractures. As a fixation method, it was quick in placement and highly adaptable, and thus, it proved to be valuable in restoring the form and function in maxillofacial trauma patients.

“…First, operative errors can be decreased but they can never be eliminated completely. Second, a slight distortion exists in the CT scan model [ 14 , 15 ]. Third, computer-assisted planning processes and validation processes have slight errors as well [ 16 ].…”

BackgroundThis study aimed to evaluate the accuracy of surgical outcomes in free iliac crest mandibular reconstructions that were carried out with virtual surgical plans and rapid prototyping templates.MethodsThis study evaluated eight patients who underwent mandibular osteotomy and reconstruction with free iliac crest grafts using virtual surgical planning and designed guiding templates. Operations were performed using the prefabricated guiding templates. Postoperative three-dimensional computer models were overlaid and compared with the preoperatively designed models in the same coordinate system.ResultsCompared to the virtual osteotomy, the mean error of distance of the actual mandibular osteotomy was 2.06 ± 0.86 mm. When compared to the virtual harvested grafts, the mean error volume of the actual harvested grafts was 1412.22 ± 439.24 mm3 (9.12% ± 2.84%). The mean error between the volume of the actual harvested grafts and the shaped grafts was 2094.35 ± 929.12 mm3 (12.40% ± 5.50%).ConclusionsThe use of computer-aided rapid prototyping templates for virtual surgical planning appears to positively influence the accuracy of mandibular reconstruction.

“…When the treatment results were assessed, there were still mistakes in the distances and measures despite getting good results. Some of the factors that probably contributed to these errors include: errors in obtaining the CT DICOM data (errors in image acquisition), errors during segmentation of DICOM data using the segmentation or the computer aided design (CAD) software (errors in creating the 3D models or in designing the 3D reduction guides), and errors during 3D printing of the guides related to the rapid prototyping process (33,34).…”

BACKGROUND:Fracture of Zygomaticomaxillary complex (ZMC) is considered to be one of the major facial fractures. it can lead to significant cosmetic and functional disorders. Three-dimensional (3-D) printing applications are gaining a remarkable attention in the field of craniomaxillofacial and plastic surgery. As the benefits of patient-specific 3-D printing become more established, surgeons are more likely to integrate this technology into their practice. AIM OF THE STUDY:This study evaluated the accuracy of the use of 3-D printed reduction guide in the treatment of zygomatico maxillary complex fractures.Patients & Methods: This study was conducted clinically on 12 adult patients with ZMC fractures indicated for open reduction and internal fixation. The patients were divided into 2 groups, (group A): the 3D printed reduction guide was used during the surgery and (group B): the surgical procedures were done without the reduction guide. The reduction and fixation time was recorded for comparison. Postoperative patient evaluation was performed with specific attention paid towards, accuracy of reduction, infra orbital nerve affection and postoperative ocular complications. RESULTS: There was a statistically significant difference in the surgical reduction and fixation time between the two groups. The error differences were more reduced for all landmarks in group (A) compared to group (B). The mean AI was decreased for all landmarks in group (A) compared to group (B). CONCLUSION: The use of 3D printed reduction guide offers shorter operation time and improves the reduction of the fractured segments in comparison to the conventional reduction techniques.
