1. Accurate display of fracture: Spiral CT scan can display the position, type and displacement of fracture and guide fracture reduction. Spiral CT can rotate at will, observe the fracture from multiple angles and observe the soft tissue injury at the same time.
2. Improve the diagnostic accuracy of occult fractures: Compared with traditional X-ray examination, spiral CT is more accurate in diagnosing occult fractures, such as orbital bone and zygomatic bone.
3. Three-dimensional reconstruction technology to guide surgical reduction: Spiral CT combined with three-dimensional reconstruction technology can intuitively display the three-dimensional relationship of fractures and provide better guidance for surgical reduction.
