128层螺旋 CT 在茎突综合征术前诊断中的临床价值

摘要

目的：探讨128层螺旋 CT 在茎突综合征术前诊断中的临床价值。方法回顾性分析50例（100侧）正常成人（对照组）和48例（96侧）经手术证实的茎突综合征患者（SPS 组）的临床及影像资料，并对两组患者的茎突长度和倾角分布的差异进行统计分析。结果对照组中，茎突过长（长度>30mm）8侧（8％），前倾角过大（角度>25°）2侧（2％），内倾角过大（角度>25°）4侧（4％）；而 SPS 组中，茎突过长56侧（58.3％），前倾角过大14侧（14.6％），内倾角过大18侧（18.8％），茎突过长伴倾角异常10侧（10.4％）。经统计学分析，SPS 组的茎突过长及倾角过大的检出率明显高于对照组，差异具有统计学意义（P<0.05）。结论茎突综合征在影像学上主要表现为茎突过长和（或）倾角过大，128层螺旋 CT 三维重建技术能为临床提供可靠的影像学依据，在茎突综合征术前诊断中具有重要临床价值。%Objective To explore the clinical value on the pre-operation of styloid process syndrome diagnosed by 128-slice spiral CT. Methods Retrospectively analyzed 50 cases (100sides) of normal adult (control group) and 48 cases(96 sides) of styloid process syndrome diagnosed by operation (SPS group). The differences between two groups in the length and angle distribution of the styloid process were analyzed statistically. Results Eight sides of control group (8%) had the elon-gated styloid process (the lenght was more than 30mm),two sides (2%) had the larger anteversion angle (the angle was more than 25°),four sides (4%) had the larger inclination angle (more than 25°);48 cases of SPS group, 56 sides (58.3%) had the elongated styloid process,14 sides (14.6%) had the larger anteversion angle, 18 sides (18.8%) had the larger inclination an-gle,10 sides (10.4%) had the elongated styloid process coupled with abnormal inclination. Analyzed by statistics, the detection rate of the elongated styloid process and abnormal inclination in control group were lower than those in SPS group, there were significant differences between the two groups (P<0.05). Conclusion Styloid process syndrome has the elongated styloid process and (or) abnormal inclination in imaging,128-slice spiral CT three-dimensional reconstruction can provide reliable evi-dence for clinic,which has important clinical value for preoperative diagnosis in styloid process syndrome.
