The use of intraoperative navigation has become prevalent in multiple surgical fields, including neurosurgery, orthopedic surgery, spine surgery, and head and neck surgery. In the past decade, its use also has become popular in oral and maxillofacial surgery. Previous studies have suggested the use of intraoperative navigation improves surgical precision and accuracy and decreases intraoperative risks and postsurgical morbidity. This report presents a case in which intraoperative navigation was used for revision and secondary reconstruction of multiple facial fractures. Preoperative virtual surgical planning allowed customization of osteotomies of multiple bony segments and virtual reduction of these segments to their anatomically correct position. Then, the newly reconstructed 3-dimensional virtual computed tomographic dataset was used as a template in the navigation system to guide the osteotomies and precisely reposition bony fragments during surgery. This report describes the workflow necessary to use this technology.
术中导航的应用在多个外科领域已变得十分普遍，包括神经外科、骨科手术、脊柱手术以及头颈外科。在过去十年中，其在口腔颌面外科的应用也逐渐流行起来。先前的研究表明，术中导航的使用提高了手术的精准度和准确性，并降低了术中风险和术后发病率。本报告介绍了一例术中导航用于多处面部骨折翻修和二次重建的病例。术前虚拟手术规划允许对多个骨段进行截骨定制，并将这些骨段虚拟复位到解剖学正确位置。然后，将新重建的三维虚拟计算机断层扫描数据集用作导航系统中的模板，以指导截骨并在手术过程中精确重新定位骨碎片。本报告描述了使用该技术所需的工作流程。
