摘　　要：目的探讨“CT导航”技术在下颌角截骨成形术中的应用。方法分析并总结近3年来，在“CT导航”下对46例施行下颌角截骨成形术，术前对患者头颈部行薄层CT扫描，将数据输人“CT导航”系统，术中在“CT导航”系统引导下行下颌角截骨成形术。结果全部患者整形效果及安全性良好，术中解剖定位准确，截骨操作简便，无明显并发症发生，手术时间短，出血少，术后康复快。结论采用“CT导航”技术不仅可精确判定重要血管、神经所在位置，避免术中误伤，提高手术安全性；而且可以从三维立体角度确定截骨的位置及骨量，有效减少并发症的发生，降低手术的风险，减轻患者心理负担，增加患者对手术成功的信心及对医者的信任度。Objective To summarize the use of the CT-guided mandibular angle plastic osteoto- my. Methods The clinical data of mandibular angle plastic osteotomy were analyzed under the CT navigation in recent 3 years in our department. Thin-slice CT scans of the mandibular angle were per- formed before the operation. The CT data were input to the system of neuronavigation. The surgical procedures were then taken under the CT navigation. Results All of patients who received this new technology obtained good plastic effects and safe operation. The anatomic location accurately achieehed with short operation time and less bleeding during the operation and distinct curative effect and fast re- covery after operation. The effects of the treatment were fine. No visible complications occurred. Con- clusions The CT navigation could fix accurately on position of important blood vessels and nerves which could be injured accidentally during operation and, of course, the safety of the operation is im- proved. The CT navigation can also determine the position and quantities of osteotomy from three di- mensional angles, reduce effectively the surgical complications and the risk of surgery, reduce the psy- chological burden of patients efficiently and increase their confidence and credibility to the operation and surgeons.
