How Is Trigeminal Neuralgia Treated?
Trigeminal neuralgia can be treated with antiseizure medications such as Tegretol or Neurontin. The medications Klonapin and Depakote may also be effective and may be used in combination with other drugs to achieve pain relief. Some antidepressant drugs also have significant pain relieving effects.
If medications are ineffective or if they produce undesirable side effects, neurosurgical procedures are available to relieve pressure on the nerve or to reduce nerve sensitivity.
Some patients report having reduced or relieved pain by means of alternative medical therapies such as acupuncture, chiropractic adjustment, self-hypnosis or meditation.
Trigeminal Neuralgia
Trigeminal neuralgia is a very debilitating disease. It is the most common facial neuralgia in patients over 50 years of age. It occurs in 4 in 100,000 people, and is diagnosed mainly by history. It is often caused by compression of the entry zone of a nerve supplying sensation to the face (trigeminal nerve) by a blood vessel.
The picture above depicts the intense pain of trigeminal neuralgia, which can be caused by even the slightest trigger, such as putting on makeup.
The trigeminal nerve leaves the brainstem, and exits the base of the skull to supply sensation to the face. It divides into three divisions of the trigeminal nerve, known as the ophthalmic, maxillary and mandibular divisions.
On the cross sectional MRI scan through the brainstem, one can see the trigeminal nerve (shown with an arrow).
Typically, the attacks of trigeminal neuralgia consist of sudden, lancinating, electric like shocks, which last several seconds. Multiple attacks may occur, but the pain is confined to one side of the face.
As is seen, there are three regions of the face, each supplied by a different branch of the trigeminal nerve. Usually, V2 and V3 are affected alone or in combination. Isolated involvement of V1 occurs in 5% of cases. Trigeminal neuralgia is more frequent in women than in men. The right side is affected more than the left.
Trigeminal neuralgia is precipitated or triggered by several factors. These include movement or stimulus to the eyebrow, upper lip, washing the face, shaving, brushing the teeth, talking or eating. Even a slight draft of wind may precipitate the trigeminal neuralgia.
Trigeminal neuralgia attacks often occur after the patient arises in the morning. It does not wake patients from their sleep, however.
Trigeminal neuralgia typically occurs in patients over 50. In younger patients with these symptoms, one must rule out multiple sclerosis or a cerebellopontine angla (CPA) tumor.
In a patient experiencing trigeminal neuralgia, the neurological exam is typically normal.
CT scans and MRI scans of the brain may be obtained to rule out another type of pathology.
Treatment options for trigeminal neuralgia range from medication to rhizotomy, to open microvascular decompression of the trigeminal nerve leaving the brainstem, to Gamma Knife radiosurgery.
Gamma Knife has an 80% to 85% chance of having a good to excellent result. The likelihood of complications using the Gamma Knife is low.
With Gamma Knife, the patient undergoes the procedure, and returns home the same day. The effects of treatment can take from days, up to 3 months to occur.
At the West Houston Medical Center Gamma Knife facility, we are experienced at performing Gamma Knife Radiosurgery Procedures for trigeminal neuralgia.
Gary Kraus, M.D. is the medical director of the Gamma Knife Center at West Houston Medical Center. Dr. Kraus’ experience with Gamma Knife started in 1999, when he started and directed the Gamma Knife Center at the Wallace Kettering Neuroscience Institute, in Dayton, Ohio. Under his direction, the center performed over 500 Gamma Knife procedures. At West Houston Medical Center, Dr. Gary Kraus is the medical director of the Gamma Knife Center, and the medical director of Neurosciences. He has 10 years of experience in treating trigeminal neuralgia with Gamma Knife.
Treatment of trigeminal neuralgia with Gamma Knife is an area in which Gary Kraus M.D. has extensive experience. He sees patients at three offices in Houston Texas which are conveniently located on the medical campuses of West Houston Medical Center, and Memorial Hermann Memorial City Hospital, as well as in Katy, Texas. His office serves patients in the Houston area, surrounding areas in Texas, as well as other states in the United States, and abroad.
