【摘要】目的探讨薄层CT扫描对颅底骨折的诊断价值。方法回顾分析41例颅底骨折患者常规CT及薄层CT扫描结果。结果本组患者均有颅底骨折的临床征象。薄层CT能清晰显示颅底骨折线、颅内积气及窦腔积液,常规CT未见明显颅底骨折线,仅见颅内积气及窦腔积液,5例薄层CT扫描阴性患者排除颅底骨折诊断。结论薄层CT扫描能为颅底骨折提供客观的诊断和鉴别依据,骨折线显示优于常规CT。

[Abstract] Objective To investigate the value of thin-setion CT in the diagnosis of basicranial fracture. Methods Regular CT and thin-setion CT findings of 41 cases with basicranial fracture were analyzed retrospectively. Results Among 41 cases with clinical symptoms and signs of basicranial fracture, 5 cases rule out basicranial fracture with negative thin-setion CT manifestation. Pneumocephalus and sinus hydrops were detected by thin-setion CT scan and regular CT scan , Thin-setion CT scan can clearly revealed basicranial fracture line while regular CT scan can not. Conclusion Conclusion The capability of thin-setion CT for detecting basicranial fracture line is superior to regular CT. It can provide reliable informations for clinically definite diagnosis and differenciation.

颅底骨折在颅脑外伤中较常见。自从CT机应用于临床以来,其诊断的准确率明显提高。一般通过直接、间接征象即可诊断,我院近5年共收治颅底骨折患者261例,多数患者通过临床表现及常规CT扫描即已确诊,其中有41例额、颞、顶部受伤患者临床疑诊颅底骨折但常规CT未检出骨折征象,行薄层CT扫描后予以确诊,现将结果报告如下。
材料与方法
1、临床资料
