The possibility of performing intraoperative computed tomography may add to the safety and efficiency of some maxillofacial procedures. It would be preferable for intraoperative image data acquisition to be available to a surgeon on demand for immediate control of therapy results.
In a pilot study, the use of a mobile computed tomographic scanner (Philips Tomoscan M, Philips Medical Systems, Eindhoven, Netherlands) was evaluated in our unit. The scanner is equipped with wheels, draws power from wall outlets in combination with batteries, and has a translating gantry.
Experience to date with six patients has confirmed the feasibility of intraoperative CT. All patients operated on were treated for craniofacial trauma. The CT images showed good spatial resolution. In all cases, visualization of the correct fragment position was excellent without causing significant delay of the operative procedure.
Intraoperative computed tomography could be the new state-of-the-art method for direct control of treatment results in maxillofacial traumatology. Nevertheless, the high expenses for installation of such technical infrastructure has to be pointed out; therefore, the routine use of this technique might be questioned.
术中计算机断层扫描的可行性可能会提高某些颌面外科手术的安全性和效率。术中图像数据采集能应外科医生的需求提供，以便即时控制治疗效果，这将更为理想。
在一项初步研究中，我们单位评估了移动计算机断层扫描仪（飞利浦Tomoscan M，飞利浦医疗系统公司，荷兰埃因霍温）的使用情况。该扫描仪配备有轮子，通过与电池结合从墙上插座获取电力，并且有一个平移式机架。
迄今对6例患者的经验证实了术中CT的可行性。所有接受手术的患者均因颅面创伤接受治疗。CT图像显示出良好的空间分辨率。在所有病例中，正确的骨折块位置显示极佳，且未导致手术过程出现明显延迟。
术中计算机断层扫描可能成为颌面创伤学中直接控制治疗效果的新的先进方法。然而，必须指出安装这种技术基础设施的高昂费用；因此，该技术的常规使用可能会受到质疑。
