Trigeminal neuralgia is known as the “No. 1 pain in the world”, which is a severe pain of electric shock-like, slash-like and tear-like, with sudden onset and stop. Patients are afraid of talking about it and do not want to remember the painful process. The so-called “trigger point” of trigeminal nerve refers to a fixed and limited patch of skin or mucous membrane within the innervation area of trigeminal nerve that is particularly sensitive, and the slightest touch of this point will immediately cause a painful attack, which will occur immediately. This point is often located in the gums, teeth, upper and lower lips, nose, corners of the mouth and buccal mucosa. In order to avoid irritation, patients often dare not wash their faces, brush their teeth, shave, smile, etc. This poses a great threat to the normal life and health of patients. Microvascular decompression is to release the compression of blood vessels on the trigeminal nerve according to the cause of the disease, so that the pain symptoms disappear. How can trigeminal neuralgia be treated and how much does it cost? The principle of microvascular decompression surgery for trigeminal neuralgia is to make a small incision of 3-4 cm behind the ear and perform the decompression operation under the microscope to relieve the compression of the nerve by the responsible blood vessels, and the disease will be completely cured. This procedure is a minimally invasive surgery and the cost of the procedure is not very high, so families can generally afford it.
