Abstract:
OBJECTIVETo investigate an available method for quantitative diagnosis of zygomatic fractures to quantitatively classify and diagnose the deformities of zygomatic fractures.
METHODSTraditional 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.
RESULTS1. 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.
CONCLUSIONSComputer-assisted 3D CT measuring system is accurate, reliable and feasible in clinic for diagnosing zygomatic fractures.
