摘　　要：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）网像，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拿硬化消失者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 tabyrinthitis. 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.
