Blood Supply of Facial Nerve
The facial nerve gets it’s blood supply from 4 vessels:
- Anterior inferior cerebellar artery – at the cerebellopontine angle
- Labyrinthine artery (branch of anterior inferior cerebellar artery) – within internal acoustic meatus
- Superficial petrosal artery (branch of middle meningeal artery) – geniculate ganglion and nearby parts
- Stylomastoid artery (branch of posterior auricular artery) – mastoid segment
The arteries form a external plexus lying within the epineurium and an internal plexus which in intraneural.
