Plane measurement of three-dimensional CT images on the diagnosis of zygomatic fractures.
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
1. 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.
