BUCKCANAN VARGAS, Aldair; MATA FUENTES, Milena  and  FONSECA ARTAVIA, Karen. Trigeminal neuralgia. Med. leg. Costa Rica [online]. 2020, vol.37, n.1, pp.130-137. ISSN 2215-5287.

Trigeminal neuralgia is a disease whose prevalence is high and corresponds to a significant percentage of facial neuralgia; where the most affected people are over 50 years old. The clinical picture is usually of episodes of severe and recurring facial pain, unilateral; in the distribution of one or more divisions of the trigeminal nerve and this is not explained with another diagnosis. Diagnosis is based on the clinic and usually no sensory deficit is found, however, if present, neuroimaging should be done to rule out other causes. In the first instance is the pharmacological management. Carbamazepine has been established as effective, leading to pain relief within 24 hours. When pharmacological therapy fails, surgery is generally divided into two: techniques that destroy the sensitive portion of the nerve and microvascular decompression, which has the best results.
