螺旋CT重建技术在颌面部骨折中的应用价值

目的 探讨螺旋CT三维重建及齿科软件技术在颌面部骨折中的应用价值。方法 选取2014年6月至2015年6月我院收治的颌面部骨折患者78例,作为研究对象。所有患者均经手术证实为颌面部骨折,对所有患者行常规X射线平片、螺旋CT平扫及三维重建、齿科软件检查,对比各种检查方案的诊断结果,分析其临床应用价值。结果 X射线平片对颌面部骨折总检出率均明显低于CT平扫与CT三维重建及齿科软件(P <0.05),CT平扫与CT三维重建及齿科软件对复合颌面部骨折确诊率比较无显著差异,(P>0.05),但CT三维重建及齿科软件技术对单纯骨折或合并牙折的总检出率明显高于CT平扫,(P <0.05)。结论 螺旋CT三位重建及齿科软件技术对颌面部骨折确诊率较高,对于各类型骨折,尤其是单纯骨折及合并牙折均有着较高的检出率,具有临床应用及推广价值。

The Application Value of Spiral CT Reconstruction Technique in Maxillofacial Fractures

Objective To explore the application value of the spiral CT three-dimensional reconstruction and dental software technology in maxillofacial fractures. Methods Randomly selected 78 consecutive hospitalized patients with maxillofacial fractures treated between June 2014 and June 2015 as the research object. All the patients were confirmed as maxillofacial fractures by operations and they were examined by conventional X-ray plain film, spiral CT scan and 3D reconstruction. Comparing different kinds of examination programs, we analyzed the values on clinical application. Results The total detection rate of maxillofacial fractures with X-ray plain film was significantly lower than that of plain CT scan and CT three-dimensional reconstruction and dental software,P<0.05, the difference was statistically significant; there was no significant difference between plain CT scan and CT three-dimensional reconstruction and dental software when compare to the complex maxillofacial fractures diagnosed rate, P>0.05, but the total detection rate of CT three-dimensional reconstruction and dental software technology for simple fracture or merger of tooth fracture was obviously higher than that of CT plain scan,P<0.05.Conclusion Spircl CT three-dimensional reconstruction and dental software technology not only have a relatively high diagnosis rate of maxillofacial fractures but also have a high detection rate of all kinds of fractures, especially for complex fractures, which has values on clinical application and promotion.
