摘　　要：目的通过对分析鼓室硬化颞骨轴位HRCT表现,评价颞骨轴位HRCT对鼓室硬化的诊断价值。方法回顾性分析20例(共20耳)经手术证实的鼓室硬化患者的颞骨轴位HRCT。结果鼓室内软组织密度影6耳,鼓室内钙化及软组织影13耳,单纯鼓膜钙化影1耳,鼓膜增厚16耳。硬化灶位于听小骨周围的19耳,其中硬化灶覆盖蜗窗的2耳。结论颞骨轴位HRCT可以显示鼓膜及鼓室内的硬化灶及病变部位,结合临床鼓膜像,进行综合分析,对鼓室硬化的诊断有指导意义。Objective By analyzing axial view HRCT of temporal bone to approach the diagnostic value to tympanosclerosis. Methods 20 axial view HRCT of temporal bone of tympanosclerosis confirmed by operation were analyzed. Results The soft tissue masses within tympanic cavity were found in 6 ears, both soft tissue masses and calcification in 13 ears. Calcification only in tympanic membranes was found in 1 ear. 16 ears were showing tympanic membrane thickening. Tympanosclerosis plaque that embraced auditory ossicles was found in 19 ears. Round windows were involved in 2 ears. Conclusions Axial view HRCT of temporal bone can demonstrate tympanosclerosis plaque in tympanic membranes and within tympanic cavity which may contribute to diagnosis of tympanosclerosis.
