By a News Reporter-Staff News Editor at Computer Weekly News -- Research findings on Surgery are discussed in a new report. According to news originating from Beijing, People's Republic of China, by VerticalNews correspondents, research stated, "To describe a new method of zygomatic surface marker navigation to treat delayed unilateral zygomatic fractures. The computed tomography (CT) data for 6 patients were obtained before surgery and imported into the surgical planning software."
Our news journalists obtained a quote from the research from Peking University, "After 3-dimensional (3D) construction and segmentation, 3D cylindrical-shaped objects in stereolithographic format were placed in position and merged with the data from the fractured segments to mark the area for surface reduction. Data from the unaffected side were used to guide the reduction data for the segments with markers. During surgery, the surface markers were marked by drilling holes in the fractured bones in a process guided by the surgical navigation plan established before osteotomy. The segments were then reduced to the predetermined places using the positions of the hole markers as guides. 3D image comparisons and axial CT measurements were used to evaluate navigation accuracy and bone symmetry. Six patients with unilateral delayed zygomatic fractures were treated using this approach. The mean deviation between the postoperative 3D images and the reduction navigation plan for the 6 patients was +1.24 mm and 1.4 mm. The mean width deviation between the affected and unaffected sides was 1.28 mm, and the mean eminence deviation was 1.22 mm. All patients were followed up for at least 3 months and experienced no obvious complications. Zygomatic surface marker-assisted surgical navigation can simplify the navigation planning for surgery and avoid the complex protocols needed to create the surgical templates."
According to the news editors, the research concluded: "The navigation accuracy was acceptable, and all 6 patients obtained good facial symmetry."
