颌面骨折是口腔颌面外科常见的外伤性疾病。但因颌面部骨质重叠,形态各异,结构复杂,二维平片往往很难将骨折情况清晰准确地显示。随着螺旋CT容积扫描及三维重建技术的应用,增大了成像的扫描范围,使采集的信息量明显增加,图像的质量也明显提高,大大拓宽了CT的能力和应用范围[1]。我科2005年开始对颌面复杂骨折患者应用螺旋CT扫描及容积三维重建,明确诊断并制订治疗方 Maxillofacial fracture is a common traumatic disease in oral and maxillofacial surgery. However, maxillofacial bone overlap, different shapes, complex structure, two-dimensional plain film is often difficult to clearly and accurately show the fracture. With the application of spiral CT volume scanning and 3D reconstruction technology, the scanning range of imaging is increased, the amount of information collected is obviously increased, and the quality of the image is obviously improved, greatly expanding the capability and application range of CT [1]. Our department began in 2005 to patients with maxillofacial complex fracture spiral CT scan and volume three-dimensional reconstruction, a clear diagnosis and the development of treatment
