Assessment of Meniere’s disease from a radiological aspect-saccular otoconia as a cause of Meniere′s disease ?

摘要: 目的:本研究拟采用3DCT来评估梅尼埃病(MD)患者的连合管(RD)、球囊管(SD)和内淋巴囊(ES)的显影情况。方法:根据美国耳鼻咽喉头颈外科学会听力与平衡委员会的诊断标准,我们采用3DCT对62例确诊为单侧MD的患者进行影像学评估,并与其对侧耳及正常对照组(26耳)进行比较,观察它们在3DCT影像中RD、SD和ES的通畅性。结果:MD患耳在3DCT影像中表现为连续性中断,与对照组比较差异有统计学意义(P<0.01)。结论:3DCT成像中,MD耳与对照耳相比,RD、SD和ES的显影明显减弱,提示内淋巴流动可能被致密物质阻断,该物质可能为球囊上脱落的耳石。RD、SD和ES可能参与MD的发病。
