目的探讨迷路炎的螺旋CT检查方法及其诊断价值.方法观察17例19耳临床提示为迷路炎同时存在异常CT表现患者的高分辨率CT(HRCT)图像,总结其内耳在HRCT图像上的影像学特点.结果进行HRCT扫描的19耳中,内耳1个或多个结构表现为密度增高者5耳,密度增高且发生变形者7耳,单纯变形者1耳,内耳迷路内腔局部或完全硬化消失者6耳,合并内耳骨质缺损者2耳.结论 HRCT可以较好显示迷路炎的异常改变,对迷路炎的临床诊断起着重要的辅助作用.

Objective To investigate the spiral CT methods and the high resoution CT (HRCT)findings of labyrinthitis. Methods The HRCT of 17 cases (19 ears) with labyrinthitis were studied. Results In the 19 ears which underwent HRCT examinations, 5 ears showed increase of the density of one or more structures of inner ear and 7 ears showed increase of the density of structures as well as change of the shape of the inner ear. 1 ear showed change of the shape only. Labyrinth inner cavity showed local or total sclerosis and disappearance in 6 ears. Among the 19 ears, there was bony incompleteness in 2 besides the changes mentioned above. Conclusion HRCT can demonstrate the abnormal changes of bony labyrinth. It has important value of detection and diagnosis of labyrinthitis.
