OBJECTIVE
To investigate an available method for quantitative diagnosis of zygomatic fractures to quantitatively classify and diagnose the deformities of zygomatic fractures.
METHODS
Traditional X-ray, two and three dimensional CT images of 96 patients with zygomatic fractures were measured and analysed by computer-assisted measuring system before and after operation to diagnose the displacement and deformity of the fractures.
RESULTS
- Using anthropology points and computer assisted measuring system, a new method was established to assess the displacement of the zygomatic fractures. 2. Displacement of the zygomatic fractures was approximately diagnosed by measuring different angle of 3D CT photographs. 3. A classification was proposed based on the deformities of the zygomatic fractures.
CONCLUSIONS
Computer-assisted 3D CT measuring system is accurate, reliable and feasible in clinic for diagnosing zygomatic fractures.
目的
探讨一种可用于颧骨骨折定量诊断的方法，对颧骨骨折畸形进行定量分类和诊断。
方法
采用计算机辅助测量系统，对96例颧骨骨折患者术前及术后的传统X线、二维及三维CT图像进行测量分析，以诊断骨折的移位及畸形情况。
结果
- 利用人类学测量点和计算机辅助测量系统，建立了一种评估颧骨骨折移位的新方法。2. 通过测量三维CT照片的不同角度大致诊断颧骨骨折的移位情况。3. 根据颧骨骨折的畸形情况提出了一种分类方法。
结论
计算机辅助三维CT测量系统在临床诊断颧骨骨折方面准确、可靠且可行。
