In normal guinea pig ears, hydrostatic perilymphatic pressure is equal to endolymphatic pressure. Alterations of perilymphatic pressure induced, for example, by laceration of the round window membrane are transmitted immediately to the endolymphatic compartment, probably via Reissner's membrane. In guinea pigs with experimental endolymphatic hydrops, however, pressure gradients between the endolymph and perilymph remained preserved after rupture of the round window membrane. This is considered as further evidence that after long-standing distention of Reissner's membrane the membranous labyrinth loses its ability to equalize endolymphatic and perilymphatic pressure.
在正常豚鼠耳中，外淋巴液压等于内淋巴压。例如，圆窗膜撕裂引起的外淋巴压力变化会立即通过Reissner膜传递到内淋巴腔。然而，在实验性内淋巴积水的豚鼠中，圆窗膜破裂后，内淋巴和外淋巴之间的压力梯度仍然存在。这被认为是进一步的证据，表明在Reissner膜长期扩张后，膜迷路失去了平衡内淋巴和外淋巴压力的能力。
