Perilymphatic and endolymphatic pressure in the normal guinea pig.
Perilymphatic and endolymphatic pressures were measured consecutively in the normal guinea pig using a WPI 900A micropressure system. The mean (n = 10) perilymphatic and endolymphatic pressures were 2.26 and 2.31 cm H2O, respectively. There was no statistically significant difference between the pressures of the endolymphatic and perilymphatic compartments. The measured values were within the range of pressures found in the literature.
