A total of 84 patients with 89 fractures of the temporal bone were examined with high resolution CT (HRCT) a few hours to 21 months after the initial trauma. Axial HRCT disclosed 63 longitudinal, 13 transverse, 10 complex and 3 atypical fractures. The diagnosis of a temporal bone fracture was established by axial HRCT in almost every case. However, for the precise topographic analysis of the course of the fracture, additional coronal HRCT proved helpful. The most common, surgically treatable complication of temporal bone fracture is disruption of the ossicular chain. Twenty-three such lesions were demonstrated by combined axial and coronal HRCT; 22 lesions of the facial canal could be demonstrated in 27 patients presenting with facial nerve palsy. The most common site of injury to the facial canal was the region of the geniculate ganglion. The only life-threatening complication of a temporal fracture may be otorhinoliquorrhea. This was present in 9 cases. The most common site of leakage identified was the tegmen tympani. With Metrizamide-HRCT precise localisation of the dural laceration was possible in 7 of these 9 cases.
84例颞骨骨折患者共89处骨折，在初次外伤后数小时至21个月期间接受了高分辨率CT（HRCT）检查。轴位HRCT显示63处纵行骨折、13处横行骨折、10处复合骨折和3处非典型骨折。几乎在所有病例中，轴位HRCT都能确诊颞骨骨折。然而，对于骨折走行的精确局部分析，额外的冠状位HRCT证明很有帮助。颞骨骨折最常见的可手术治疗的并发症是听骨链中断。轴位和冠状位HRCT联合显示了23处此类病变；在27例面神经麻痹患者中，22处面神经管病变得以显示。面神经管最常见的损伤部位是膝状神经节区域。颞骨骨折唯一危及生命的并发症可能是耳鼻漏。9例出现耳鼻漏。确定的最常见漏出部位是鼓室盖。在这9例中的7例中，通过甲泛葡胺-HRCT能够精确确定硬脑膜撕裂的位置。
