What is trigeminal neuralgia?
Trigeminal neuralgia means nerve pain in the face, teeth,
mouth, or nasal cavity. It may occur on one or both
sides of the face. Trigeminal neuralgia is also called tic
douloureux.
How does it occur?
Trigeminal neuralgia occurs most often in women over age 40,
although it may occur in men or women of any age. The
problem appears suddenly and may get better on its own. It
may also disappear for months or years, only to return. An
attack of trigeminal neuralgia often brings stabbing or
burning pain that comes in sudden jabs. This may last from
1 to 15 minutes. The most common areas of attack are the
cheeks and jaw.
An attack usually follows some sort of trigger. These may
include:
- a light touch to the area
- brushing teeth
- chewing or swallowing
- exposure to hot or cold air or drinks.
The frequency of the attacks varies from person to person.
Between attacks, most people are free of pain. Some may
have a dull ache. The causes are not well understood. The
problem may result from:
- a short circuit between touch and pain nerves
- multiple sclerosis
- infection of the nerve by herpes simplex virus.
What are the symptoms?
The person may favor the area of the face by trying to hold
it still. He or she often stops washing and shaving the
area and may keep it covered.
How is it diagnosed?
Your health care provider will ask about your symptoms and
medical history. He or she will examine you. Tests may be
needed to rule out other causes of pain such as infections
of the teeth or sinuses. You may have a magnetic resonance
imaging (MRI) scan to check for multiple sclerosis or a
tumor as a cause of the pain. Your health care provider may
also refer you to a neurologist, neurosurgeon, or
physiatrist for additional testing.
How is it treated?
Anticonvulsant medicines, muscle relaxants, and antianxiety
medicines may help and may be used in combination to
relieve pain. If medicine does not provide relief, you
might consider surgery. There are methods to remove part of
the nerve. These include electrosurgery, microsurgery, and
radio wave surgery.
After surgery, the affected area will lose the pain and its
sense of touch. You must be very careful to watch for future
physical problems that usually cause pain, such as:
- burns
- dry eyes (when the blink reflex has been lost)
- chewing-related problems and gum and dental problems
(when oral sensation has been lost).
Some people may find pain is reduced or relieved by
acupuncture, chiropractic adjustment, self-hypnosis, or
meditation.
