The hydrostatic pressure of the inner ear depends on the cerebrospinal fluid pressure through the cochlear aqueduct. The time-course of inner ear pressure change following rapid change in cerebrospinal fluid pressure is related to the aqueduct patency. In this study the patency of the cochlear aqueduct in 27 patients with Menière's disease (28 affected ears, 16 non-affected ears) and in 12 normal hearing subjects (18 control ears) was assessed non-invasively by means of the MMS-10 Tympanic Displacement Analyser. Following a rapid change in body position, changes in intracranial cerebrospinal fluid pressure were found to influence perilymphatic pressure within 1 min. No significant differences were found among affected ears, non-affected ears and control ears.
内耳的静水压力通过蜗水管取决于脑脊液压力。脑脊液压力快速变化后内耳压力变化的时间过程与蜗水管通畅性有关。在本研究中，通过MMS-10鼓膜位移分析仪对27例梅尼埃病患者（28只患耳，16只未患耳）和12名听力正常受试者（18只对照耳）的蜗水管通畅性进行了无创评估。身体位置快速改变后，发现颅内脑脊液压力变化在1分钟内影响外淋巴压力。患耳、未患耳和对照耳之间未发现显著差异。
