脑脊液压力的变化通过耳蜗导水管反映在淋巴周围，并可能通过Reiss-ner膜传递到内淋巴。我们的结果似乎驳斥了内淋巴压力由脑脊液经内淋巴囊和管传递的假说。在正常的迷路中，淋巴周围和淋巴内的压力在我们测量的精度范围内是相等的。耳蜗导水管的有效横截面和圆窗膜的膨胀特性可能是防止脑脊液突然变化的保护机制。内淋巴和外淋巴之间的压力梯度必须保持在2厘米以下的水，这个值是破裂的预期值。因此，如果淋巴管周围的压力不受影响，那么在淋巴管高压的情况下，压力对感觉细胞的损害是非常不可能的，而当耳蜗导水管打开时，淋巴管周围的压力很可能受到影响。……的扩张。
Cerebrospinal fluid pressure changes are reflected in perilymph via the cochlear aqueduct and are passed on to the endolymph, probably via Reiss-ner's membrane. The hypothesis that the endolymph pressure is transmitted by the cerebrospinal fluid via the endolymphatic sac and duct appears to be refuted by our results. In the normal labyrinth the peri-lymphatic and endolymphatic pressure are equal within the accuracy of our measurements. The effective cross section of the cochlear aqueduct together with the expansion properties of the round window membrane may serve as a protective mechanism against sudden changes in the cerebrospinal fluid. A pressure gradient between endolymph and perilymph will have to stay below 2 cm of water, a value at which rupture is to be expected. Therefore, damage to the sensory cells due to pressure in case of an endolymphatic hypertension is very improbable, provided the perilymphatic pressure is not affected, which is likely when the cochlear aqueduct is open. The expansion of...
