Endolymph is unlike any other extracellular fluid found in the body. Its predominant cation is potassium; sodium is very low. Like perilymph, it is generally believed that endolymph is not homogeneous in its ionic composition throughout the inner ear.

When considering the clinical syndromes of pressure sensitivity, such as found in superior canal dehiscence, perilymph fistula, and Meniere's disease, one naturally must also think about the various interfaces that the inner ear has to other compartments -- spinal fluid and the air pressure in the middle ear.

The anatomy of the inner ear is dominated by large fluid-filled spaces. As shown in this figure, the inner ear consists of a complex series of tubes, running through the temporal bone of the skull. The bony tubes (sometimes called the bony labyrinth) are filled with a fluid called perilymph.

General agreement exists that perilymphatic fistula (PLF) occurs and that leakage of perilymph from the inner ear into the middle ear can cause acute hearing loss, ... PLF is thus a form of inner ear fluid imbalance. Ménière disease, another form of inner ear fluid imbalance, occurs when endolymph is present in overabundance.
