目的：以往的研究中，前庭水管（VA）的确定使用轴向CT，已表明，VA的大小在梅尼埃病患者小于那些在对照组的主题，25-35%的梅尼埃病的耳朵是“不可见型”。“在这项研究中，除了获得轴向尺寸外，我们还使用垂直多平面重建（MPR）图像测量了垂直平面沿着的VA尺寸。方法：使用垂直MPR和轴向CT图像测量了单侧梅尼埃病患者（n = 34）和对照组（n = 30）的双耳VA尺寸。结果：在所有受试者中沿轴向和垂直面沿着测量VA大小。VA轴位图像上测量的参数彼此相关，而垂直MPR图像上测量的参数与轴位图像上测量的参数不相关。梅尼埃病患耳和非患耳的参数值往往小于对照耳。受影响的和未受影响的耳朵的患者与梅尼埃病的VA窗孔的外部孔面积显着小于为对照ears.Conclusion：我们的研究结果表明，垂直参数的VA产量的信息是独立的轴向参数提供的。单侧梅尼埃病患者双耳的VA均较对照耳薄。(C)2012爱思唯尔爱尔兰有限公司保留所有权利。
Objective: Previous studies, in which the vestibular aqueduct (VA) was determined using axial CT, have indicated that the VA sizes in patients with Meniere's disease were smaller than those in the subjects of the control group and that 25-35% of ears with Meniere's disease were "non-visible type." In this study, in addition to obtaining the axial size, we measured the VA size along the vertical plane by using vertical multiplanar reconstruction (MPR) images.Methods: The VA size of both ears of patients with unilateral Meniere's disease (n = 34) and of subjects of the control group (n = 30) was measured by using the vertical MPR and the axial CT images.Results: The VA size was measured along the axial and vertical planes in all subjects. The parameters measured on the axial image of the VA correlated with each other: however, the parameters on the vertical MPR image did not correlate with those on the axial image. Values of parameters in the affected and nonaffected ears with Meniere's disease tended to be smaller than those in the control ear. The external aperture areas of the VA fenestra of the affected and nonaffected ears of patients with Meniere's disease were significantly smaller than that for the control ears.Conclusion: Our findings suggest that the vertical parameters of the VA yield information that is independent of that provided by the axial parameters. In both ears of patients with unilateral Meniere's disease, the VA tended to be thinner than those in the control ear. (C) 2012 Elsevier Ireland Ltd. All rights reserved.
