4. Introduction
• A chronic pain condition affecting the trigeminal nerve in the face.
• Evidence suggests that in up to 95% of cases, trigeminal neuralgia is
caused by pressure on the trigeminal nerve close to where it
enters the brain stem
• This type of trigeminal neuralgia is known as primary trigeminal
neuralgia.
• Trigeminal neuralgia corresponds to a clinical manifestation of
sudden severe paroxysms of excruciating pain on one side of
the face which usually lasts a few seconds to a few minutes,
involving one or more branches of the trigeminal nerve (CN V).
• Vascular compression is the most prevalent cause
• Mostly the culprit is superior cerebellar artery
