摘要
目的 探讨“一点一线垂直法”茎突CT薄层冠状扫描在诊断茎突过长中的价值。方法测量72例双侧茎突的长度、方位、形态、厚度、尖端与咽侧壁距离,总结茎突过长病人的临床症状与诊断。 结果 ①41例67侧长度超过3.0cm,符合茎突过长的诊断;②12例12侧茎突虽未超过3.0cm(均在2.5～2.9cm),且茎突方位角>20°、末端与咽侧壁的距离<20mm,并有临床症状的应考虑茎突过长综合征;③按茎突的形态进行分型:锥型(分直锥、弧锥),束状型,分节型,发育不良型。其中分节型与临床症状有密切关系。结论 ①茎突CT薄层冠状扫描能清晰显示茎突的长度、形态、厚度、末端与咽侧壁距离,是诊断茎突过长的一种可靠方法;②“一点一线垂直法”茎突CT薄层冠状扫描无需进行图像重建,可操作性强、简捷易行、便于推广。
Objective To investigate the value of thin slice coronary CT scanning of sty-loid process (SP) with the 'one point-one vertical line' localizing procedure for the diagnosis of styloid process syndrome (SPS). Methods 72 cases were included in this study to test their length, direction, shape and thickness of SP and the distance between its tip and lateral wall of pharynx. Then, an analysis was made on the relationship of clinical symptoms with SPS diagnosis. Results 41 cases (67 sides) were found to have SP length more than 3. 0 cm, satisfied the diagnostic standard of SPS, and 12 cases (12 sides) were seen with SP length less than 3. 0 cm (2. 5-2. 9cm), azimuth larger than 20°,and the distance between SP tip and lateral wall of pharynx less than 20 mm. For the latter cases, they were considered with the condition of SPS because of them being seen with clinical symptoms suggesting such a case, even though their SP length being under the diagnostic value. Furthermore, the shape of SP could be classified into such types as taper (including straight and arc) , bundle, segmental and hypogenetic ones, based on the images of CT scanning, Among these SP types, segmental one was closely related with the occurance of clinical symptoms. Conclusion This procedure is reliable for the diagnosis of SPS because of its advantages in clearly showing these indexes and is simple and easy to operate since no reconstruction of images is needed to show the whole SP at one slice.
