title: [Craniofacial neuralgias].
abstract: Craniofacial neuralgias are characterized by sudden paroxysmal pain along the distribution of one or more of the cranial or upper cervical spinal nerves. The most significant neuralgia of the craniofacial region is trigeminal neuralgia, while geniculate neuralgia, glossopharyngeal neuralgia and occipital neuralgia are less common. Trigeminal neuralgia may be primary or secondary. Idiopathic trigeminal neuralgia or tic douloureux has been recognized for centuries as an extremely painful disorder most commonly involving the maxillary nerve. Recurrent lancinating, shocklike unilateral pain lasting for seconds to minutes is provoked by non noxious stimulation of the skin at specific sites around the face and less frequently by movement of the tongue. The trigger zones are usually within the same dermatome as the painful sensation. After each episode, there is usually a refractive period during which stimulation of the trigger zone will not induce pain. Idiopathic trigeminal neuralgia occurs somewhat more frequently in women and usually begins in individuals 50 to 70 years of age. There is no pain between attacks, and the frequency of painful episodes can range from several per day to only a few per year. With time, the features may become more atypical, with greater areas of more enduring and dull pain and occasionally bilateral pain, rarely on both sides simultaneously. No sensory or reflex deficit is detectable by routine neurologic testing. Diagnostic local anesthetic blocks will identify the specific nerves involved and the trigger point distribution. Neurologic and neuroradiologic examination is advised in all cases to rule out diseases such as intracranical tumors, vascular malformations or multiple sclerosis.
