Trigeminal neuralgia is a disorder of the trigeminal nerve (the fifth cranial nerve) that causes episodes of sharp, stabbing pain in the cheek, lips, gums, or chin on one side of the face.
The trigeminal nerve, which is divided into three branches, is responsible for chewing, for producing saliva and tears, and for sending facial sensations to the brain. When this nerve breaks down for some reason, it can trigger brief but agonizing sizzles of pain on one side of the face.
This condition is unusual in those under age 50 and more often occurs after 70. Women are three times more likely to have the condition than are men. When trigeminal neuralgia does occur in younger people, it is often associated with multiple sclerosis.
The pain, while brief, is so severe that the sufferer often can't do anything else while the attack lasts. People with this pain often wince or twitch, which is where trigeminal neuralgia gets its French nickname tic douloureux, meaning "painful twitch."
Causes and symptoms
The origin of trigeminal neuralgia is not certain, but scientists believe it may be caused by degeneration,
pressure, or irritation of the trigeminal nerve. Some doctors believe the pain may be triggered by pressure from a nearby abnormally-formed artery lying too close to the nerve.
Any part of the three branches of the trigeminal nerve may be affected. Neuralgia of the first branch leads to pain around the eyes and over the forehead; the second branch causes pain in the upper lip, nose and cheek; the third branch causes pain on the side of the tongue and lower lip.
The first episodes are usually fairly mild and brief, and it may be minutes, hours, or weeks before the next attack. However, attacks tend to occur in clumps that may last for weeks at a time. As the sufferer ages, the episodes become more frequent and painful, until the person begins to live in constant fear of the next one.
The momentary bursts of pain usually begin from the same spot on the face each time. The pain can be triggered by touching the area, washing, shaving, eating, drinking, or even talking. Even a cool breeze across the face can set off an attack. Pain is more severe at the ends of the affected nerve, especially over the lip, chin, nostrils, or teeth.
Diagnosis is usually made by eliminating other problems that could cause similar pain in teeth, jaw, head, or sinuses. Because patients with the condition tend to avoid trigger points, avoiding chewing, shaving, touching or washing their faces can be a clue to diagnosis of trigeminal neuralgia.
It is not easy to treat trigeminal neuralgia. Pain can be suppressed by a range of medicines, including the anti-epilepsy medicines carbamazepine (Tegretol) or phenytoin (Dilantin). These drugs slow down the nerve signals at certain nerve terminals, which eases the pain. However, these drugs cause a wide range of side effects, including nausea, dizziness, drowsiness, liver problems, and skin allergies. Some people develop resistance to the drugs or they can't tolerate the high dosage needed to control the discomfort. If the medicines are stopped, the pain usually returns.
If drug treatment fails, surgical treatment to block pain signals from the nerve may be effective. Radio-frequency waves, gamma rays, or glycerol injections can deaden the nerve (and hence the pain). An operation that frees the nerve from whatever is compressing it (blood vessel or tumor) can permanently relieve pain, but this major neurosurgical procedure carries its own risks and complications. Alternatively, a new procedure seeks to place a cushioning sponge between the nerve and a pulsating artery wrapping around it to soothe the irritated nerve.
Although the pain is momentarily incapacitating, it's not life-threatening. As the person ages, the attacks can be expected to occur more and more frequently.
While the condition itself can't be prevented, there are a number of things patients can do to avoid triggering attacks:
- wash with cotton pads and warm water over the face
- rinse the mouth with water after eating, if tooth-brushing triggers pain
- eat and drink food and beverages at room temperature
- chew on the unaffected side
- eat soft foods, if eating is becoming a problem

Multiple sclerosis — A progressive disease of the central nervous system in which the coverings of nerves in the brain and spinal cord are destroyed.
pain in a nerve or along the course of one or more nerves, usually consisting of a sharp, spasmlike pain that may recur at intervals. It is caused by inflammation of or injury to a nerve or group of nerves. Inflammation of a nerve, or neuritis, may affect different parts of the body, depending upon the location of the nerve. Two common types of neuralgia are that of the trigeminal nerve (see tic douloureux) and that of the sciatic nerve (see sciatica). adj., adj neural´gic.

a neurological condition of the trigeminal facial nerve, characterized by paroxysms of flashing, stablike pain radiating along the course of a branch of the nerve from the angle of the jaw. It is caused by degeneration of the nerve or by pressure on it. Any or all of the three branches of the nerve may be affected. Neuralgia of the first branch results in pain around the eyes and over the forehead; of the second branch, in pain in the upper lip, nose, and cheek; of the third branch, in pain on the side of the tongue and the lower lip. The momentary bursts of pain recur in clusters lasting many seconds. Paroxysmal episodes of the pains may last for hours. Also called prosopalgia, tic douloureux.

trigeminal neuralgiaA disorder of the sensory nerve of the face, the trigeminal nerve, on one side in which sudden episodes of excruciating stabbing pain occur in the cheek, lips, gums, chin or tongue.
