How do perilymph and endolymph differ
WebThe main difference between endolymph and perilymph is their location and function. What is a perilymph? A perilymph fistula (PLF) is a tear in either one of the membranes separating your middle and inner ear. Your middle ear is filled with air. Your inner ear, on the other hand, is filled with fluid called perilymph. WebThe endolymphatic system contains intracellular-like fluids with high potassium and low sodium concentrations, whereas the perilymphatic fluid resembles the extracellular fluid with low potassium and high sodium concentrations. Ion pumps are constantly at work in the cell membranes of the labyrinth to maintain these electrolyte separations.

WebA perilymph fistula (PLF) is an abnormal connection (a tear or defect) in one or both of the small, thin membranes (the oval window and the round window) that separate the air filled middle ear and the fluid filled perilymphatic space of the inner ear. This small opening allows perilymph (fluid) to leak into the middle ear.
