Trigeminal neuralgia is a painful condition that occurs in one side of the head, face, jaw, and around the dental cavity in the area innervated by the trigeminal nerve. Typical trigeminal neuralgia is characterized by paroxysmal, brief pain episodes, each lasting from a few seconds to a few minutes, intense and unbearable pain, pain in the form of electric burns, pins and needles, knife-cutting, tearing, etc. The episodes may be accompanied by facial muscle convulsions, with the corners of the mouth drawn to one side; the pain mostly occurs unilaterally and never spreads to the midline, with trigger points (trigger points) along the distribution area of the trigeminal nerve, such as the upper and lower lips, corners of the mouth, teeth, tongue, and cheeks. There are often trigger points (trigger points) along the trigeminal nerve distribution area, such as the upper and lower lips, corners of the mouth, teeth, tongue, and cheek, which can be triggered when washing, brushing, drinking, talking, and shaving, seriously affecting patients’ daily life. Minimally invasive surgery is one of the most effective methods to cure trigeminal neuralgia. During the surgery, the contact between the nerve and blood vessels is effectively blocked, the internal conduction disorder of the nerve is corrected, and the patient’s pain symptoms disappear immediately after the surgery. Since minimally invasive surgery is performed under a microscope, it does not damage the patient’s nerves and blood vessels and has few postoperative complications, more and more patients are choosing minimally invasive surgery to treat trigeminal neuralgia.
