摘    要:颅面骨畸形手术是一种相当复杂的外科手术,为了确保手术成功,通常需要进行细致而全面的术前设计。然而,多数临床医生很难根据简单的二维CT、X光图片设计出令病人信服满意的手术方案。在本研究中,针对单侧眼眶畸形情况提出了基于三维重建技术和眼眶容积测量方法的虚拟手术系统。此系统应用三维重建技术实现了骨骼位置的重置,而双眼眶容积测量结果将用来指导骨骼位置的重置。文中所给出的一名患者应用该系统进行术前手术设计的关键过程以及该患者术前、术后的对比图片用以表明该系统在辅助外科医生进行术前设计的有效性。

关 键 词:颅面手术  三维重建  容积计算  手术设计

Abstract:The surgical treatment of craniofacial malformation is a s ophisticate task which need s careful and detailed preoperative planning. However, based on the patient's 2 - D CT and X-ray images, the surgeons always feel hard to produce a convincible a n d satisfying surgical scheme. In this article, a craniofacial surgery simulation system based upon 3-D reconstruction and volume calculation of two eye soc kets is presented. By using this system, the surgeon can virtually repose bone fragme nt according to the D-value between the volumes of two eye sockets. The D-valu e serv es as a guideline to direct the bone reposing. The simulated key steps of real s urgical procedure are presented, which demonstrate the efficiency of the system. The contrast images between postoperative and preoperative surgery are also giv en.
Keywords:Craniofacial surgery    3-D reconstruction    Volume calcula tion    Surgical plan
