摘　　要：分三组观察梅尼埃病 (Meniere′sdiseaseMD)患者前庭小管 (Vestibularaqueduct,VA)CT影象 ,即正常耳组、非MD　眩晕组及MD组。每组均行头颅轴位CT扫描观察 ,并测量VA外口径。结果显示正常组及非MD眩晕组VA显影良好 ,不显影率均为 9.1%。MD患者VA不显影率为 75 % ,显影的VA外口也狭小。提示VA不显影或狭窄是其发育不良的表现 ,可作为诊断MD的影象学依据之一。Objective To study the vestibular aqueduct(VA) with CT in Meniere , s disease(MD). Method The experiment consisted of three groups: normal ear group, non-MD vertigo group and MD group. VA in each group was examined with CT, and the width of the external aperture of VA was measured.Result VA in normal ear group and non MD vertigo group was well visualized,and non visualization rate was 9.1%. VA non visualization rate in MD group was 75%, external aperture was narrowed in VA patients. Conclusion non visualization or narrowing of the enterhal aperture can be considered as one of the diagnostic sings of MD.
