摘要
颅颌面解剖结构复杂使得外科手术难度较大,因此十分必要进行术前模拟以保证手术成功,颅颌面结构的三维重建与手术仿真是目前国内外研究的热点。应用薄层CT扫描数据集,利用Mimics软件对336层,层厚为1.0mm的CT二维图像数据进行分析处理,并进行颅颌面的三维重建研究与虚拟手术设计。初步建立了数字化可视颅颌面虚拟手术仿真平台,并精确地模拟了颌面外科常见的3种手术方式,即LefortⅠ截骨术、下颌角截骨术和颏成形术。结果提示在普通计算机上应用Mimics软件可以建立数字化可视颅颌面虚拟手术仿真平台,并对其应用进行了探讨,为科研、教学及临床手术规划提供了方便、快捷、直观的方法,并就虚拟手术设计在普通计算机上的应用进行了讨论。
Anatomic structure in craniofacial region is very complicated and orthognathic surgery is difficultly performed. Therefore, it is necessary to generate virtual surgical model from CT scan data before operation on personal computer in order to make surgery more accurate. This technique has been increasingly interested in the field of orthognathic surgery both at home and abroad. The sample was scanned with thin-layer CT. CT image data （336 layer, 1.0 mm slice thickness） were analyzed with the Mimics software. Simultaneously, three-dimensional model and virtual surgery of the facial cranium were established. The digitized virtual surgical platform of faciat cranium was preliminarily created, and three common surgical methods in maxillofacial surgery, i.e., LeFort 1 osteotomy, mandibular angle osteotomy, and genioplasty, for maxillofacial surgery were simulated. The results showed that the digitized virtual surgical platform of facial cranium could be generated with the Mimics software on personal computer, which provides convenient and quick methods for research, teaching, and clinical surgery. More importantly, it creates theoretical basis for virtual surgical platform which can be widely used on personal computer.
