For patients with hemifacial spasm, a loop of the anterior inferior cerebellar artery, posterior inferior cerebellar artery, or vertebral artery compresses the ipsilateral facial nerve at the root exit zone, leading to involuntary contractions of the facial musculature.

It crosses the superior cerebellar artery close to the cerebral peduncles, passes the lateral edge of the clivus bone, and runs under the petroclinoidal ligament into the cavernous sinus between the double layer of dura and connective tissue at its lateral border, just below the oculomotor nerve and above the ophthalmic branch of the trigeminal (5th cranial) nerve.
The superior cerebellar artery is the most common cause of compression.
Blood flow was diminished in the left vertebral and basilar arteries that supplied the posterior fossa, the superior cerebellar artery off the basilar artery, and the right posterior internal communicating artery off the right vertebral artery.
It is also possible for vertigo to develop as a result of interruption of the blood supply to the brainstem VNC or cerebellum, which arises mainly from the posteroinferior cerebellar artery, the anteroinferior cerebellar artery (VNC and cerebellum), and the superior cerebellar artery (cerebellum) (Baloh, 1996b).
Aneurysm site: ICA internal carotid artery, ACA and MCA are anterior and middle cerebral arteries, PICA posterior inferior cerebellar artery, and ACoA is the anterior communicating artery.
