“…However, in our study the success of orbital fracture repair depends not only on the use of material that restores the premorbid orbital volume and shape, but also the capacity to visualize the geometry of the bony defect spatially and to place the titanium mesh to fit the original contour with no evidence of inflammatory and fibrogenic response to the surrounding tissue. This in agreement with Kim, et al 2017 (12) and Ellis et al 2004 (13). Whose reported that, titanium mesh has been cited as being an excellent alloplastic material for use within the orbit as it has a low rate of extrusion and infection which has been attributed to the tendency of titanium to cause an inflammatory and fibrogenic response to the surrounding tissue.…”

INTRODUCTION: Orbital reconstruction is one of the most challenging tasks for the surgeon who treats craniofacial trauma. Suboptimal outcomes may lead to debilitating morbidity with significant emotional, functional, and occupational deficits OBJECTIVES: This study was designed to compare the efficacy of the computer-aided fabricated individual titanium mesh and conventional titanium mesh in orbital skeleton reconstruction in cases of infraorbital dysesthesia. MATERIALS AND METHODS: The study population included 20 patients with orbital skeleton fractures. The sample was selected conveniently to fulfill a list of inclusion criteria. The selected participants were randomly allocated into two equal groups, each group included 10 patients. In the course of a surgical treatment, individually designed titanium mesh were manufactured by application of computer-aided design in combination with rapid prototyping technologies (CAD/RP). Preoperative analysis and postoperative monitoring were conducted to evaluate their success based on restoration of infraorbital nerve function that was evaluated by pin prick test and electrical pulp testing. RESULTS: Regarding postoperative clinical evaluation, group 1(study group) was superior to that of group 2 (control group) in restoring the function of infraorbital nerve CONCLUSIONS: computer aided titanium mesh was an accurate option in reconstructions of traumatic orbital wall fractures.

“…Conventional, manually-bent plates have been found to be less accurate than pre-bent implants in the reconstruction of fractures with a 3-dimensional printed prototype of a skull. 4,5 Pre-bent plates have similar results to polyethylene-titanium hybrid implants and there is no difference in complication rates. 6 https://doi.org/10.1016/j.bjoms.2018.08.008 0266-4356/© 2018 The British Association of Oral and Maxillofacial Surgeons.…”

Preoperative virtual planning and the use of patient-specific implants enable exact reconstruction of orbital fractures. We present our results and experience of reconstruction of isolated orbital fractures with patient-specific implants, according to the Helsinki protocol, in 15 patients who were followed up for at least three months postoperatively. The mean (range) difference between the positions of virtually planned, and postoperative, implants was 1.9 (0.5-5.6) mm. The postoperative volume of the fractured orbit was 1.34ml less than that of the non-fractured side, but this was not clinically relevant. None of the patients required reoperation and none had any implant-related complications during follow up. We conclude that patient-specific implants are an adaptable and reliable treatment for primary orbital trauma, and that the Helsinki protocol may have wider applications in the treatment of facial fractures.

“…Three-dimensional printing is increasingly used for surgical planning; surgical simulation; and predictable, accurate, and efficient reconstruction in facial trauma. 2,4,7,11,13 Important considerations were apparent while we were engineering our workflow, especially while comparing with other similar techniques in the literature. Wagner et al 7 described 2 cases in which rapid 3D prototyping was used.…”
