简介：目的探讨高分辨率颞骨CT密度在诊断耳硬化中的作用。方法分析手术确诊的耳硬化患者34例（34耳，病例组）和同期确诊的周围性面瘫患者33例（对侧正常耳33耳，对照组）的颞骨CT扫描和纯音听阈测试结果。在0．75mm层厚颞骨CT轴位层面的耳囊周围，手动设置7个兴趣区，测量平均cT值。根据CT表现将耳硬化病例分为2个亚组：A组，CT显示无病理变化；B组，耳蜗区骨密度降低。比较各兴趣区病例组与对照组平均CT值的差异，分析病例组CT表现与纯音测听结果的关系。结果卵圆窗后缘和卵圆窗前缘这两个兴趣区，病例组平均CT值明显低于对照组（卵圆窗后缘t=-2．030，P=0．046；卵圆窗前缘Z=-4．979，P〈0．01）。A组30例，包括传导性聋9例（30％），混合性聋21例（70％）；B组4例，包括传导性聋1例（25％），混合性聋3例（75％）。结论耳硬化患者卵圆窗周围骨质CT密度可能发生改变。

简介：甲状腺相关性眼病是一种与甲状腺疾病相关的器官特异性自身免疫性疾病，其病理表现为大量糖胺聚糖堆积，导致眼球突出，上睑挛缩，复视等临床表现。根据疾病活动性，可以进行活动期与静止期的分类。目前甲状腺相关性眼病活动性评价主要依据患者的症状和体征，以及影像学检查。细胞因子、黏附分子及糖胺聚糖的研究，为甲状腺相关性眼病活动性的客观评价提供了广阔的前景，现做一综述。
