Definition[Bearbeiten]
The labyrinthine artery is a branch of the basilar artery responsible for the blood supply to the inner ear.
Course[Bearbeiten]
The labyrinthine artery is a thin and long artery that originates from the basilar artery or the anterior inferior cerebellar artery (AICA). It runs through the pontocerebellar cistern and runs parallel to the vestibulocochlear nerve into the internal acoustic meatus. Its end branches run to the cochlea and semicircular canals.
Branches[Bearbeiten]
- Arteria vestibuli
- Arteria cochlearis communis
- Arteria vestibulocochlearis
- Arteria cochlearis propria (follows the winding of the cochlea, see also: Stria vascularis)
Supply area[Bearbeiten]
The labyrinthine artery supplies the inner ear, auditory system and vestibular system with arterial blood. Its end branches in the inner ear are relevant for the production of endolymph.
Clinic[Bearbeiten]
The involvement of the labyrinthine artery in the development of tinnitus is repeatedly discussed, even if the study situation for this hypothesis is not clear.
