Trigeminal neuralgia is a common neurosurgical disorder that involves recurrent episodes of severe pain in the sensory distribution of one or more branches of the trigeminal nerve in the head and face, also known as “pain in the face”. It is characterized by rapid onset, lightning-like, slashing, burning, intractable and severe pain. Patients describe this pain as the most intense in the world, and the pain is intolerable and even suicidal. The annual incidence of trigeminal neuralgia is reported to be about 4.5/100,000, with a generally higher incidence the older the patient is, and the incidence in women is twice as high as in men. The pain mostly starts from one maxillary branch or mandibular branch and gradually spreads to both branches or even all three branches are involved. In typical patients with trigeminal neuralgia, there is often one or more special sensitive skin areas within the distribution of the affected branches of the trigeminal nerve, and pain can be triggered by slight stimulation, such areas are called trigger points, also known as trigger points. Some patients even refuse to drink or eat, causing malnutrition, which seriously endangers patients’ physical and mental health and brings great harm to society. The longer the course of the disease, the more frequent the attacks will be and the heavier the symptoms will be, causing a great psycho-physiological burden to the patients, which has caused great concern to the majority of clinicians.
