What is trigeminal neuralgia?
Aneuralgia (or neuralgia) of the trigeminal nerveit is a nervous disorder that causes extremely severe pain in the region of the face through which the trigeminal nerve passes.
Otrigeminal nerveit is a nerve that runs on each side of the face, divides into 3 branches and is responsible for the sensitivity of that region of the face. When there is injury, inflammation or compression of the nerve, it generates excruciating pain in the territory of the involved branch, which may be in only one branch or in more than one.

Causes of Trigeminal Neuralgia
They existvarious causesfor trigeminal neuralgia. The most common areneurovascular conflicts, in which an artery or even a vein touches the nerve. Not every time a blood vessel touches any symptom and tests such as magnetic resonance imaging, although indicated, many times are not able to determine an exact cause.
Other causes likemultiple sclerosis e tumores(mostly benign) can also occur and a single imaging test such as MRI is able to rule out these causes.
Existem várias motivos para a dor da neuralgia do trigêmio ainda se manter. O primeiro é o tratamento está errado, ou até mesmo o diagnóstico. Outra possibilidade, é o tratamento apesar de correto ser insuficiente, e o ajuste de dose ser necessário. Por fim, o remédio pode ser necessário ser trocado ou adicionado, como adicionar o tratamento com toxina botulínica.
Além disso, existem casos refratários, e aí a cirurgia é o melhor caminho.
Embora não seja uma cura, há grande possibilidade de com a cirurgia, haver remissão das dores.
