Blood-flow regulation in the inner ear, particularly the cochlea, has been the subject of many studies reported so far, and the special characteristics of capillary plexuses and arteriovenous (AV) anastomoses in the stria vascularis and spiral ligament are well known. With regard to the vestibule, on the other hand, basic studies on blood flow regulation have been insufficient and incomplete, although reports are available on unique features of blood vessels. In some cases of dizziness due to vestibular disorder, circulatory disturbance of the vestibule has been implicated as the underlying cause and, in fact, circulatory agents are in common use in the treatment of the condition.
