摘要
背景：组成面中部的诸骨均为立体结构,颧骨等在受伤时经常发生位置、角度等的改变,在常规的面中部骨折治疗中,特别是面中部复合骨折或陈旧性骨折,恢复其立体结构的位置、角度等是较为困难的,而应用计算机导航系统就为术中恢复其解剖形态的准确性提供了较为可靠的依据。目的：观察计算机辅助导航在面中部骨折治疗中的应用效果,并探讨应用中的注意事项。方法：选择北京积水潭医院口腔科及眼科2007-03/2008-08收治的面中部骨折患者6例,其中眼眶-上颌-颧骨复合骨折4例,上颌骨LeFortⅢ型骨折2例。均采用计算机辅助导航系统辅助手术,术前通过CT采集数据,利用导航计划软件进行术前设计,术中利用导航工作站对手术适时导航,行切开复位内固定。结果与结论：计算机辅助导航系统可以使面中部骨折的治疗做到术前准确设计、术中精确定位,复位后经6-12个月随访疗效满意。提示应用计算机导航系统能提高面中部骨折复位的准确性,是一项值得推广的技术。
BACKGROUND：The spatial structure of midface leads to changeable in injury,and difficult to recover especialy for obsolete fracture.The application of computer-assisted navigation system provides a reliable basis for midfacial fracture treatment.
OBJECTIVE：To explore the application result and precautions of computer-assisted navigation system in midfacial fracture treatment.
METHODS：Totally 6 midfacial fracture cases received treatment at the Departments of Dentistry and Ophthalmography,Beijing Jishuitan Hospital were selected,including 4 cases with orbital-maxillary-zygomatic compound fracture and 2 cases with LeFort Ⅲ maxillary fracture.Computer-assisted navigation system was used in the treatment.Data were collected by CT,and navigation software was used for preoperative design.During the operation,the navigation workstation was used for guidance and open reduction and internal fixation was performed.
RESULTS AND CONCLUSION：The computer-assisted navigation system could facilitate accurate preoperative design,precise surgical location,and satisfactory results were obtained in 6-12 months follow-up.It suggested that computer-assisted navigation system is a valuable technique,which could increase the reposition precision of midfacial fracture.
