How do perilymph and endolymph differ

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. Webthe ion differences between endo- and perilymph create a voltage difference across the hair cells of ~ +80 mV (positive on the endolymph side). This voltage difference contributes …
