Trigeminal neuralgia is a paroxysmal electric shock-like severe pain that occurs in the area of distribution of the trigeminal nerve and lasts for seconds or minutes, with intermittent periods of no symptoms. The course of the disease is cyclical and the pain can be spontaneous or caused by stimulation of the trigger point. Most trigeminal neuralgia starts at the age of 40 years, mostly in middle-aged and elderly people, especially in women, and its onset is more on the right side than on the left side. The disease is characterized by sudden onset and stoppage, lightning-like, slash-and-burn, intractable and severe pain in the trigeminal nerve distribution area of the head and face. For trigeminal neuralgia treatment methods are: 1, oral Western medicine treatment, can play a temporary pain relief or relief role, such drugs have resistance, oral dose gradually increase, the effect is getting worse. 2.Closure therapy, using acupuncture point injection drugs to paralyze and block the nerve, to play the role of temporary pain relief. 3, radiofrequency surgery treatment, also known as thermal coagulation. 4.Acupuncture and laser treatment: often can once relieve pain. 5.X-knife and gamma knife treatment: the nerve is burnt by radiation, which is costly and can also cause postoperative hair and sequelae. 6.Surgical treatment, which can be divided into peripheral neurectomy, nerve root amputation, trigeminal spinal cord bundle amputation, etc., but they all destroy the trigeminal nerve and make it lose its normal physiological function to achieve temporary pain relief, which can cause facial nerve paralysis, hemiparesis, ataxia and other sequelae, and have a high recurrence rate. Nowadays, as the view that vascular compression of nerves causes pain is widely recognized and microsurgery techniques are widely carried out, microvascular decompression of the trigeminal nerve can release local vascular compression while preserving the intact sensory transmission of the trigeminal nerve, and there is no loss of facial sensation, so it is suitable for patients with intractable facial spasm and patients with glossopharyngeal neuralgia. Our department has successfully applied microvascular decompression to treat trigeminal neuralgia, facial spasm and glossopharyngeal neuralgia, with a cure rate of over 95%. The procedure has become the most effective treatment method of choice because of its low trauma, high safety and cure rate, low complication rate, and especially the complete preservation of blood vessel and nerve function. Anyone without systemic organic pathology such as severe cardiovascular disease and under 75 years of age can be considered for treatment by microvascular decompression.
