目的探讨以咽痛为主症候群的茎突过长症螺旋CT诊断价值。方法通过对以咽痛为主症候群疑为茎突过长症患者45例进行螺旋CT扫描,并行多平面、多角度旋转技术重建,观察茎突的立体解剖及其与邻近结构的关系。结果经螺旋CT三维重建清楚显示茎突在三维空间的全貌,从而准确地测量其长度和角度,有32例患者确诊为茎突过长症。结论对以咽痛为主症候群并疑为茎突过长症患者,螺旋CT三维重建能准确诊断,对临床手术入路的选择具有重要的指导价值。 Objective To investigate the diagnostic value of spiral CT in the diagnosis of styloid process syndrome. Methods Spiral CT scan was performed in 45 patients suspected of pharyngodynia with sore throat as the main syndrome. The multiplanar and multi-angle rotation techniques were used to reconstruct the three-dimensional anatomy of the styloid process and its relationship with adjacent structures. Results Three-dimensional reconstruction by spiral CT clearly shows the whole picture of the styloid process in three-dimensional space, so as to accurately measure the length and angle of the styloid process. Thirty-two patients were diagnosed as overgrowth. Conclusion For the patients with sore throat as the main symptom and suspected to be hypersplenism, the three-dimensional reconstruction of spiral CT can be diagnosed accurately and has important guiding value for the choice of clinical surgical approach.
