Only one case had length of styloid process less than 30mm and inclined angle less than 25 degree on both sides. Conclusion: Excessive length of styloid process and abnormal angle play important role in diagnosing styloid process. 64slice spiral CT three dimension VR and MPR can display styloid process clearly in three dimension space, measure the length exactly, and show the relationship between styloid process and tissue around distinctly. It is a precise and ideal way for diagnosis of styloid process.
