Magnetic resonance volumetric measurement of inner ear endolymphatic space (ELS) was performed in patients without vertiginous or cochlear symptoms. The existence of the ELS in patients with chronic rhinosinusitis (CRS) was shown. The ELS in the cochlea and vestibule was classified into four categories. These findings could be useful as a standard reference for further research.
To identify normal values of the ELS in the cochlea and vestibule.
Twenty-four patients with CRS were enrolled. Inner ear fluid space images and positive perilymph/positive endolymph images were acquired using a 3.0-tesla unit. Three-dimensional (3-D) images were constructed semi-automatically using both anatomical and tissue information by fusing the 3-D images of the inner ear fluid space and the ELS.
Among all patients, the mean ELS/the total fluid space (TFS) ratio in the cochlea was 8.8% and that in the vestibule was 16.2%. The ELS in the cochlea and vestibule was classified into four categories. Age-related differences were found in the TFS, ELS, and ELS/TFS ratio in the inner ear and the ELS and ELS/TFS ratio in the vestibule.
对无眩晕或耳蜗症状的患者进行了内耳内淋巴间隙（ELS）的磁共振容积测量。结果显示慢性鼻窦炎（CRS）患者存在ELS。耳蜗和前庭的ELS分为四类。这些发现可作为进一步研究的标准参考。
确定耳蜗和前庭中ELS的正常值。
招募了24例CRS患者。使用3.0特斯拉设备获取内耳液间隙图像和阳性外淋巴/阳性内淋巴图像。通过融合内耳液间隙和ELS的三维图像，利用解剖学和组织信息半自动构建三维（3-D）图像。
在所有患者中，耳蜗中ELS/总液间隙（TFS）的平均比值为8.8%，前庭中为16.2%。耳蜗和前庭的ELS分为四类。在内耳的TFS、ELS和ELS/TFS比值以及前庭的ELS和ELS/TFS比值中发现了与年龄相关的差异。
