[Diagnosis and treatment of atypical facial pain-a review.].
Atypical facial pain is a collective term used for otherwise unclassifiable pain syndromes of the face. It describes mostly unilateral lancinating and burning pain, which is constantly present but fluctuating in intensity and may be accompanied by dys-or paraesthesias over a period of several years. Women are more often affected than men. A strikingly large number of invasive investigative procedures are performed before the final diagnosis is established. Psychopathological abnormalities are frequent and do not consist solely in masked depression. To date there is no cure for atypical facial pain. Most frequently tricyclic antidepressants such as amitriptyline and imipramine, MAO inhibitors or anticonvulsives such as carbamazepine and phenytoin are used, which only alleviate the pain. This also holds true for behaviour therapy, which should be the first-line treatment. Any invasive intervention should be avoided. In the differential diagnosis atypical facial pain should be distinguished from cervicogenic or cluster headache, and also from intracranial tumours of the trigeminal nerve or the cerebellar-pontine angle, erosive tumors of the base of the skull, orbitas and nasopharynx.
