High-resolution computed tomography (CT) was performed on 31 patients clinically suspected of having petrous bone fracture. The location of the fracture was demonstrated accurately in 28 patients (90.3%), whereas it could be diagnosed by plain skull film in only 17 patients (54.8%). The anatomic location of fractures demonstrated by high-resolution CT clearly corresponded to the clinical symptoms and signs. We have classified petrous bone fracture into five types according to the anatomic levels demonstrated on CT images. The findings indicate that high-resolution CT is extremely useful for diagnosing petrous bone fracture.
对31例临床怀疑有岩骨骨折的患者进行了高分辨率计算机断层扫描（CT）。28例患者（90.3%）骨折部位显示准确，而普通颅骨平片仅能诊断出17例患者（54.8%）。高分辨率CT显示的骨折解剖位置与临床症状和体征明显相符。根据CT图像上显示的解剖层面，我们将岩骨骨折分为五种类型。研究结果表明，高分辨率CT对诊断岩骨骨折极为有用。
