With the continuous progress of science and technology, there are now more and more methods of treating trigeminal neuralgia, of which gamma knife treatment of trigeminal neuralgia has also made continuous progress. The following are the advantages of gamma knife treatment of trigeminal neuralgia: 1, high safety: the whole process of gamma knife treatment patients are in a state of wakefulness, there is no case of death directly in the treatment. The damage to normal brain tissue and important neural structures is also much smaller than craniotomy or even no damage, the safety is very high. 2, short hospitalization: the vast majority of patients treated with Gamma Knife can be discharged the next day, generally only need to be hospitalized for 3 to 5 days. No longer recovery period is required as in surgery, the patient can soon return to the physical state before treatment, the advantages of gamma knife treatment of trigeminal neuralgia are many. 3, treatment cost fixed: will not increase the cost of treatment in the process of treatment, and will not increase the burden of the family because the treatment period is too long. 4, the efficacy of the treatment is predictable: in most cases before treatment can be expected to change the condition after treatment. Its factors leading to sudden changes in the condition are far less than those of surgical treatment. The effective rate is over 90% and the cure rate is over 80%. 5.Less pain: most of them are one-time treatment, and the treatment ends on the same day; patients feel no obvious changes before and after the treatment, and are not affected by work and study. 6, small trauma: positioning framework is fixed in the skull, not penetrate the skull, after treatment only in four fixed points on the scalp to form four pinhole-sized trauma, generally three days to heal, will not leave a scar affecting the appearance. 7, no bleeding: because the gamma knife is not a real scalpel, will not directly damage the blood vessels and cause bleeding like craniotomy. 8, no infection: Gamma knife treatment because of the non-cranial, will not cause intracranial infection.
