Hello, primary trigeminal neuralgia is mostly caused by long-term pulsating compression of blood vessels near nerve roots, which leads to the degeneration of nervous system, causing local false circuits and amplifying pain. At present, the most effective treatment is microvascular decompression of trigeminal nerve root. In some way, the blood vessels near the trigeminal nerve root were separated from the blood vessels pressed on the trigeminal nerve root, so that the blood vessels no longer clung to the nerve root, the pulsatile impact disappeared, the nerve function slowly recovered and the trigeminal neuralgia was cured. This is the most ideal method to treat trigeminal neuralgia at present. For some reasons, such as the elderly or poor health, there are other treatments, such as radiofrequency ablation of trigeminal nerve roots to relieve pain, destructive surgery, such as avulsion of trigeminal nerve roots, etc., which can treat trigeminal neuralgia, but microvascular decompression of trigeminal nerve roots is the most effective and the lowest recurrence rate at present.
