Abstract:
Objective To discuss the application of spiral computed tomography and reconstruction technology for patients of depressed nasal bone. Methods The patients of transsection location were backlying on the scan bed and continuously scanning in spiral, and baseline was acou-infraorbital line. The reconstructed image with 2mm layer thickness and 1.5mm overlap can be selected SSD liminal value as bone -wide and surface threshold. Results SSD image can be clearly demonstrated than general nasal bone cross-section profile in the shape, location, size and suitability of filled composite. Conclusion The surface shadow display can be shown nasal bone structure realistically, the three-dimensional anatomic structure images of vessels and the effect of bionics. The bone of volume, distance and angle can be measured exactly by clinical physician, and made the best treatment plan based on the images.
