目的:探讨X线数字断层融合技术显示颞骨茎突的方法及在茎突过长综合征诊断中的价值。方法:收集茎突过长综合征患者15例,所有病例均做X线数字断层融合检查,其中有7例做了三维CT重建检查。结果:有11例患者茎突过长超过2.5 cm,有4例患者茎突长度在正常范围。结论:X线数字断层融合技术能直观显示颞骨茎突,较平片具有明显的优势,方法易掌握,较CT费用低廉,在诊断茎突过长综合征中具有较大的应用价值。
Objective: To explore the method of X-ray digital tomography to display the temporal branch of the styloid process and its value in the diagnosis of syncope. Methods: Fifteen patients with sudden protuberance syndrome were collected. X - ray digital tomography was performed in all cases. Seven cases underwent 3D CT reconstruction. RESULTS: In 11 patients, the styloid process exceeded 2.5 cm and in 4 patients the length of the styloid process was within the normal range. Conclusion: X - ray digital tomography can visualize the styloid process of the temporal bone. Compared with the plain film, it has obvious advantages. The method is easy to master and has a lower cost than CT. It is of great value in diagnosing the sudden change of the styloid process.
