摘要
目的：为了了解岩尖气房的发病率及其临床意义。材料与方法：在日常工作中将听眶线上2cm高度平面图象中能清楚见到岩尖部与斜坡的头部CT轴位扫描2596例，不包括岩尖显示不好的病例，选择其中有岩尖气房的图象200例。调节适宜的窗口技术，观察岩尖气房的图象。结果：根据本文资料，岩尖气房的发生率约为13％，低于文献资料的发生率。近半数病例为单侧岩尖气房。在岩尖气房图象中约13％是大的单气房。讨论：CT是观察岩尖气房发育的简单而可靠的方法。我们建议岩尖综合征患者的检查中用CT扫描取代岩骨X线摄片。
Purpose: To find out the incidence on the axial CT image and the clir ical significance of the petrosal - tip cells.Materials and Methods: 200 cases with petrosal - tip cells have been collected in 2596 axial cranial scan on the level above 2cm OM -line. These images are adopted if are demonstrated the petrosal - tip and the clivus well and those are discarded if not. To take optimal window technique for image of the apexparties petrosae ossis temporalis. Results: On the basis this paper, the incidence of the petrosal cells account for 13 % in examined population, less than literatures. Unilateral petrosal - cells occur approximately one half and nearly 13 percent appearing as a large single cell in this series. Conclusion: CT is a simple, reliable technique for demonstrating the development of the petrosal cells. CT recommended to a method for evaluationg Gradenigo's Syndrome. CT may completely replacement roentgenography.
