The degree of visualization of the petrosquamosal (Körner's) septum on high-resolution axial computed tomography (CT) in 141 temporal bones (100 subjects) was analyzed. The superior and inferior parts of the septum were assessed separately and were seen in 75% and 41% of cases, respectively. There was no relation between the size of Körner's septum and pneumatization. The clinical relevance of this finding is discussed. The CT features of the ventral petrosquamosal suture also were investigated. The crista tegmentalis, a contribution of the petrosal tegmen to the mandibular fossa, was seen on CT as a polypoid excrescence projecting from the ventrolateral petrous pyramid. This knowledge is useful in the radiographic analysis of the course of longitudinal fractures of the petrous bone.
对141块颞骨（100名受试者）的高分辨率轴向计算机断层扫描（CT）上岩鳞（科纳氏）隔的可视化程度进行了分析。分别评估了隔的上部和下部，分别在75%和41%的病例中可见。科纳氏隔的大小与气化之间没有关系。讨论了这一发现的临床相关性。还研究了腹侧岩鳞缝的CT特征。骨盖嵴是骨盖对下颌窝的贡献，在CT上表现为从腹外侧岩锥突出的息肉样赘生物。这一知识在岩骨纵向骨折病程的影像学分析中很有用。
