结论：对无眩晕或耳蜗症状的患者进行了内耳内淋巴间隙（ELS）的磁共振体积测量。慢性鼻窦炎（CRS）患者存在ELS。耳蜗和前庭的ELS分为四类。这些发现可能是有用的，作为一个标准的参考，为进一步research.Objectives：确定正常值的ELS在耳蜗和vestible.Methods：24例CRS患者参加。使用3.0特斯拉装置采集内耳液体空间图像和阳性外淋巴/阳性内淋巴图像。结果：在所有患者中，耳蜗的ELS/总液体空间（TFS）平均为8.8%，前庭的ELS/总液体空间平均为16.2%。耳蜗和前庭的ELS分为四类。在内耳的TFS、ELS和ELS/TFS比率以及前庭的ELS和ELS/TFS比率中发现了与耳蜗相关的差异。
Conclusion: 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.Objectives: To identify normal values of the ELS in the cochlea and vestibule.Methods: 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.Results: 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.
