Trigeminal neuralgia, known as the first pain in the world, is a very common clinical cranial nerve disease. It is mainly manifested as paroxysmal severe pain in the trigeminal nerve distribution area of one side of the face. The pain is like knife cutting, needle stabbing, fire burning and lightning, which is recurrent and unbearable and causes great torment to people. Trigeminal neuralgia is mainly due to the compression of the trigeminal nerve root by the surrounding blood vessels, which causes paroxysmal pain in the trigeminal nerve distribution area of the face. For the treatment of trigeminal neuralgia, many hospitals take a conservative approach in internal medicine. For example, taking the western medicine carbamazepine, which can have a relatively obvious effect of relieving pain in the early stage of the disease, but with the passage of time, the dosage may need to be gradually increased, and the effect of the medicine will gradually weaken, and even in the end, it will not work at all. Therefore, this kind of drug treatment is the symptom but not the root cause, only temporary pain relief. There are other treatment methods like acupuncture, radiofrequency thermal coagulation therapy, gamma knife treatment and so on, but the effect is not ideal. At present, microvascular decompression is recognized as the standard surgery for trigeminal neuralgia, which is very mature and safe. At present, we are widely carrying out microvascular decompression surgery for the treatment of trigeminal neuralgia, which has achieved good results in clinical practice and is well received and recognized by patients. So what are the benefits of this trigeminal nerve microvascular decompression surgery? Invited expert Prof. Chen Guoqiang pointed out that the benefit of trigeminal nerve microvascular decompression is that it is a minimally invasive surgery, with little trauma, quick recovery, remarkable effect, and no damage to the trigeminal nerve, preserving the sensation of the face.
