The vestibular system is a sensory apparatus that detects information about the position and movement of the head and body in space.
The peripheral sensory structures of the vestibular apparatus are closely connected with auditory ones. The cavities of the bony labyrinth enclose a complex system of canaliculi bounded by connective membranes called the membranous labyrinth. The ducts of the membranous labyrinth are filled with endolymph, while the outer spaces contain perilymph. These two fluids have very different ionic compositions. Therefore, since acoustic and vestibular receptors are within the ducts, homeostasis of the labyrinthine fluids is essential to preserve their function.
Labyrinthine fistula (LF) is a pathological condition with abnormal communication between the inner ear and the middle/mastoid cavity.
