ABSTRACT
[Objective]To investigate the value of 16-slice spiral CT(MSCT)postprocessing in styloid process in vivo and provide the vivisection data for diagnosing and curing styloid process syndrome.[Method]Totally 100 volunteers with normal styloid processes underwent 16-slice spiral CT(MSCT). Based on the initial datum,4 kinds of postprocessing including multiple planar reconstruction(MPR), curve planar reconstruction(CPR),surface shaded display(SSD) and volume rendering (VR) were performed.The length and inclination angle of stytoid processes were measured. The distance of between styloid processes and carotid canal external aperture,jugular foramen, stylomastoid foramen ,mastoid process, internal carotid artery and internal jugular vein were surveyed. [Result]The average length of styloid processes was 24.51 mm?3.05 mm, left was 24.33 mm?3.15 mm and right was 24.69 mm?2.95 mm. The anterior inclination angle was 19.35??2.92? and medial was 24.00??4.07?.The distance of between styloid processes and carotid canal external aperture, jugular foramen,stylomastoid foramen ,mastoid process , internal carotid artery and internal jugular vein were 8.53 mm?2.45 mm, 2.87 mm?0.88 mm, 2.34 mm?0.74 mm, 17.23 mm?1.85 mm,6.49 mm?1.58 mm and 3.70 mm?1.46 mm respectively. [Conclusion]Sixteen-slice Spiral CT postprocessing demonstrate the stytoid processes in vivo accurately and fully, among which multiple planar reconstruction and surface shaded display are more valuable, because they can evaluate the length and inclination of the styloid processes and the distance between the processes and their surrounding structures in vivo more accurately.
