Internal Auditory Vein

The internal auditory vein as seen in Gray's Anatomy.

The Internal Auditory Vein is a small vein that drains the inner ear and is a part of the venous system of the human body. It is located within the internal auditory canal, alongside the internal auditory artery and the facial nerve.

Structure

The internal auditory vein originates from the cochlea and the vestibule of the inner ear. It then travels through the internal auditory canal, where it joins the anterior inferior cerebellar artery to form the labyrinthine artery.

Function

The primary function of the internal auditory vein is to drain blood from the inner ear, which includes the cochlea and the vestibule. This is crucial for maintaining the health and function of these structures.

Clinical significance

Due to its location, the internal auditory vein can be affected by various conditions such as vestibular schwannoma, meningioma, and internal auditory canal stenosis. These conditions can lead to hearing loss, vertigo, and other symptoms.
