Definition of Trigeminal neuralgia

Trigeminal neuralgia: Also called tic douloureux. Inflammation of the trigeminal nerve (the fifth cranial nerve) that most commonly causes paroxysms of very intense lightning pain in the areas of the face the nerve supplies -- the lips, eye, nose, scalp, forehead, gums, cheek, and chin -- on the involved side of the face. A less common "atypical" form of the disease causes a more constant, dull, burning, or aching pain.

See also: Trigeminal nerve.
