As the saying goes, “toothache is not a disease, but a pain that kills”, many patients choose to go to dentistry, take anti-inflammatory and painkilling drugs, and even have their teeth pulled out with little relief from toothache, because they misdiagnose trigeminal neuralgia as toothache and do not receive proper treatment. Trigeminal neuralgia, known as the “world’s first pain”, is common in middle-aged and elderly people, and refers to the pain that occurs on one side of the head, face, paranasal, jaw and around the dental bed. The pain is like cutting, stabbing, tearing, burning or electric shock, which is unbearable and even unbearable for people. Each pain attack lasts only a few seconds to a few minutes and stops abruptly. At the beginning of the disease, the number of episodes is small and the interval is long, ranging from several minutes to several hours. The pain attacks decrease at night. Pain attacks can be triggered by talking, eating, washing, shaving, brushing and wind blowing, which can cause patients to become depressed, act cautiously, and not even dare to wash their faces, brush their teeth, eat, and speak carefully for fear of causing attacks. The pain often has trigger points, also known as “trigger points”, often located in the upper lip, nose, gums, corners of the mouth, tongue, eyebrows and other places. Light touch or stimulation of the trigger point can trigger a painful attack. The pathogenesis of trigeminal neuralgia is widely believed to be due to long-term compression of the trigeminal nerve by blood vessels in the brain, resulting in demyelination of the trigeminal nerve and abnormal conduction of the nerve fibers within the trigeminal nerve. The trigeminal nerve is a nerve fiber that transmits sensation to the face, just like a thick electric wire. Due to the vascular compression, the outer skin of the wire is worn down and the inner wire filaments are exposed, resulting in a short circuit and sparking of the wire, therefore, trigeminal neuralgia mostly manifests as transient electric shock, knife cut, needle prick, and burning-like pain. Treatment methods for trigeminal neuralgia, such as oral carbamazepine, acupuncture, massage, radiofrequency, etc., are not effective because all the above treatments are not directed at the cause of trigeminal neuralgia. At present, the only method that can effectively cure trigeminal neuralgia is the “microvascular surgery decompression method”, in which the blood vessels compressing the trigeminal nerve are pushed apart, and then medical “Teflon” cotton is inserted between the nerve and the blood vessels, thus effectively blocking the contact between the nerve and the blood vessels. This effectively blocks the contact between the nerve and the blood vessel, and the internal conduction disorder of the nerve is corrected, and the patient’s pain symptoms disappear immediately after the surgery. Since the microvascular decompression method is a minimally invasive surgical treatment method, the operation is done under a microscope without damaging the patient’s nerves and blood vessels, and there are few postoperative complications.
