Perilymphatic Duct

The perilymphatic duct (ductus perilymphaticus, pna, bna; ductus perilymphaceus, jna) - also known as the cochlear aqueduct, is a thin canal connecting the perilymphatic space of the inner ear with the subarachnoid space of the brain.

Perilymphatic fluid circulates through the perilymphatic duct from the labyrinth of the inner ear to the subarachnoid space, where it mixes with the cerebrospinal fluid. This duct provides a constant flow of perilymph, which is necessary to maintain normal hearing and balance. Damage to the perilymphatic duct can lead to hearing impairment and dizziness.

The perilymphatic duct is a narrow canal in the cochlea that connects the middle ear to the inner ear or labyrinth. Through this duct, the perilampha, the liquor fluid that fills the spaces of the inner ear, enters the inner ear, where it mixes with the fluid contained in the pyramids. The perilampha is a constant medium for the lateral and medial vestibular nerves.

Perilymphatic fluid is produced by the endolymph of the middle ear. In the inner ear it is stored in lacunae. Then she falls into a special channel, which leads her further to
