It involves a very concentrated and precise beam of radiation that is directed at the trigeminal nerve to relieve the pain. The surgeons use MRI and CT scans to generate a detailed image of the head to locate the trigeminal nerve. Then, they work with radiation oncologists and physicists to deliver the radiation treatment, which takes about 45 minutes. This procedure is painless and is performed without anesthesia. The relief may last for several years, but in some cases the nerve may recover from radiation and resume transmitting pain.
Side effects are minimal and may include fatigue and facial numbness, so the recovery time is brief. Patients who have tried medications and surgical options and keep experiencing debilitating pain may qualify for clinical trials to help manage trigeminal neuralgia. These studies typically explore new medications that have a potential to provide the desired pain relief.
Speak to your neurosurgeon if you are interested in joining a clinical trial for trigeminal neuralgia. Meditation, wellness clinics and lifestyle modification programs are also options for those looking for more natural trigeminal neuralgia treatments or a supplemental treatment after surgery.
Although not fatal, trigeminal neuralgia pain and the anxiety it causes can erode the quality of life not only for the person suffering, but for those around them. Understanding the severity of the pain the person is going through and being accommodating are the first steps to caring for a loved one with trigeminal neuralgia.
Other steps may include:. It is essential to work closely with experienced and compassionate health care providers who can help find the best therapeutic approach for each person. Health Home Conditions and Diseases. Trigeminal Neuralgia Facebook Twitter Linkedin Pinterest Print What You Need to Know Trigeminal neuralgia most frequently affects people older than 50, and the condition is more common in women than men.
What is trigeminal neuralgia? Trigeminal neuralgia is sometimes known as tic douloureux, which means "painful tic. Causes of Trigeminal Neuralgia Trigeminal neuralgia usually occurs spontaneously, but is sometimes associated with facial trauma or dental procedures.
Trigeminal Neuralgia Symptoms Trigeminal neuralgia occurs more often in women than men, is more common in older people usually 50 and older , and occurs more on the right than the left. Trigeminal neuralgia symptoms may include: Episodes of sharp, intense, stabbing pain in the cheek or jaw that may feel like an electric shock. Pain episodes may be triggered by anything touching the face or teeth, including shaving, applying makeup, brushing teeth, touching a tooth or a lip with the tongue, eating, drinking or talking — or even a light breeze or water hitting the face.
Periods of relief between episodes. Anxiety from the thought of the pain returning. Trigeminal Neuralgia Pain The trigeminal nerve splits off into three branches: ophthalmic, maxillary and mandibular.
Trigeminal Neuralgia Treatment Most common over-the-counter and prescription pain medicines don't work for people with trigeminal neuralgia, but many modern treatments can reduce or eliminate the pain.
The doctor may recommend one or more of these approaches: Trigeminal Neuralgia Medications Many people who suffer from trigeminal neuralgia successfully manage this condition for many years with medication.

The trigeminal nerve, also called the fifth cranial nerve, mediates sensations of the face and eye as well as many of the muscle movements involved in chewing.
It is the largest of the twelve cranial nerves , and like the others, it is a peripheral nerve that originates in the brainstem. The trigeminal nerve is most commonly associated with trigeminal neuralgia , a condition characterized by severe facial pain.
Since it is large and has several divisions, the trigeminal nerve or its branches can also be affected by a number of medical conditions including infections, trauma, and compression from tumors or blood vessels.
Everyone has two trigeminal nerves—a right trigeminal nerve and a left trigeminal nerve—and they are exactly the same in size and appearance. The trigeminal nerve is composed of several main branches, which include a motor nerve and three sensory nerves. The three sensory nerve branches of the trigeminal nerve—the ophthalmic nerve, the maxillary nerve, and the mandibular nerve—converge in the trigeminal nerve at an area called the trigeminal ganglion to bring sensory information into the brain.
The motor nerve branch of the trigeminal nerve is smaller than the sensory branches and exits from the brainstem through the root of the trigeminal nerve. The trigeminal nerve roots and ganglion, like those of other cranial nerves, are located right outside the brainstem.
The brainstem is the lower part of the brain that serves as the physical connection between the spinal cord and the cerebral cortex of the brain. All 12 cranial nerves 12 in each side emerge from the brainstem. The trigeminal nerve ganglion is located outside the pons of the brainstem, which is below the midbrain the upper part of the brainstem and above the medulla the lower part of the brainstem.
The sensory input is received in these small nerve branches, which send their messages to the main sensory branches of the trigeminal nerve, then the trigeminal nerve root. The motor branch travels to the lower part of the head, face, mouth, and jaw to control mastication chewing. The small sensory branches of the trigeminal nerve have sensory endings located throughout the face, eyes, ears, nose, mouth, and chin. The branches of the trigeminal nerves travel along the pathways listed below. The frontal nerve, the lacrimal nerve, and the nasociliary nerves converge in the ophthalmic nerve.
These nerves and their small branches are located in and around the eye, forehead, nose, and scalp. The ophthalmic nerve enters into the skull through a small opening called the superior orbital fissure before it converges in the main branch of the trigeminal nerve. The region of the face that transmits sensation through the ophthalmic nerve is described as V1.
There are 14 small sensory nerves that converge to form the maxillary nerve. The sensory nerve endings are located in the scalp, the forehead, cheeks, nose, upper part of the mouth, and the gums and teeth. These nerves converge into four larger nerve branches—the middle meningeal nerve, the zygomatic nerve, the pterygopalatine nerve, and the posterior superior alveolar nerve—which converge to form the maxillary branch of the trigeminal nerve.
The maxillary nerve enters into the skull through an opening called the foramen rotundum. The maxillary nerve detects sensation in the middle part of the face, and this sensory area is often described as V2. A nerve that receives input from nine branches, the mandibular nerve is largely sensory, but it has motor components as well.
But trigeminal neuralgia can progress and cause longer, more-frequent bouts of searing pain. Trigeminal neuralgia affects women more often than men, and it's more likely to occur in people who are older than Because of the variety of treatment options available, having trigeminal neuralgia doesn't necessarily mean you're doomed to a life of pain. Doctors usually can effectively manage trigeminal neuralgia with medications, injections or surgery. Trigeminal neuralgia care at Mayo Clinic. Trigeminal neuralgia results in pain occurring in an area of the face supplied by one or more of the three branches of the trigeminal nerve.
If you experience facial pain, particularly prolonged or recurring pain or pain unrelieved by over-the-counter pain relievers, see your doctor. In trigeminal neuralgia, also called tic douloureux, the trigeminal nerve's function is disrupted. Usually, the problem is contact between a normal blood vessel — in this case, an artery or a vein — and the trigeminal nerve at the base of your brain.
This contact puts pressure on the nerve and causes it to malfunction. The symptoms of several pain disorders are similar to those of trigeminal neuralgia. TNP results from an injury or damage to the trigeminal nerve. TNP pain is generally described as being constant, dull and burning. Attacks of sharp pain can also occur, commonly triggered by touch. Additional mimickers include:. TN can be very difficult to diagnose, because there are no specific diagnostic tests and symptoms are very similar to other facial pain disorders.
Therefore, it is important to seek medical care when feeling unusual, sharp pain around the eyes, lips, nose, jaw, forehead and scalp, especially if you have not had dental or other facial surgery recently. The patient should begin by addressing the problem with their primary care physician. They may refer the patient to a specialist later. A high-resolution, thin-slice or three-dimensional MRI can reveal if there is compression caused by a blood vessel.
Newer scanning techniques can show if a vessel is pressing on the nerve and may even show the degree of compression. Compression due to veins is not as easily identified on these scans. Tests can help rule out other causes of facial disorders.
TN usually is diagnosed based on the description of the symptoms provided by the patient, detailed patient history and clinical evaluation. There are no specific diagnostic tests for TN, so physicians must rely heavily on symptoms and history. Physicians base their diagnosis on the type pain sudden, quick and shock-like , the location of the pain and things that trigger the pain.
Physical and neurological examinations may also be done in which the doctor will touch and examine parts of your face to better understand where the pain is located.
There are several effective ways to alleviate the pain, including a variety of medications. Other medications include: baclofen , amitriptyline , nortriptyline , pregabalin , phenytoin , valproic acid , clonazepam , sodium valporate , lamotrigine , topiramate , phenytoin and opioids. There are drawbacks to these medications, other than side effects. Some patients may need relatively high doses to alleviate the pain, and the side effects can become more pronounced at higher doses.
Anticonvulsant drugs may lose their effectiveness over time. Some patients may need a higher dose to reduce the pain or a second anticonvulsant, which can lead to adverse drug reactions. Many of these drugs can have a toxic effect on some patients, particularly people with a history of bone marrow suppression and kidney and liver toxicity.
These patients must have their blood monitored to ensure their safety. If medications have proven ineffective in treating TN, several surgical procedures may help control the pain. Surgical treatment is divided into two categories: 1 open cranial surgery or 2 lesioning procedures.
