Trigeminal neuralgia, also known as painful facial tics. It is sometimes called “facial pain” and is easily confused with toothache. Trigeminal neuralgia is a recurrent paroxysmal severe neuralgia in the distribution area of the trigeminal nerve in the face. Trigeminal neuralgia is one of the common diseases in neurosurgery, and it is also one of the internationally recognized difficult and complicated diseases. Most of the trigeminal neuralgia starts at the age of 40, and it occurs mostly in middle-aged and elderly people, especially in women, and its incidence is more on the right side than on the left side. Painful facial twitching caused by trigeminal neuralgia is characterized by sudden onset, sudden cessation, lightning-like, slash-like, burning-like, persistent, intolerable and severe pain in the distribution area of trigeminal nerve in the head and face. The etiology and pathogenesis of painful facial convulsions are unknown, but most believe that the lesions are in the periphery of the trigeminal nerve, i.e., within the sensory roots of the semilunar ganglion of the trigeminal nerve. According to microsurgical and electron microscopic observations, it may be related to small vascular malformations, bony malformations in the rocky bone area, and other factors that cause painful episodes. In Chinese medicine, it is thought to be due to “wind-cold-dampness” and a heavy cold attack on the head. Trigeminal neuralgia symptoms are mainly manifested by facial pain, and with the development of the disease, it is often painful to the patient. There are many clinical treatments for trigeminal neuralgia, such as Western medicine, traditional Chinese medicine, acupuncture, surgery, and so on. Although there are many treatment methods, but the effect is mixed, unscientific treatment will jeopardize the health of the patient, and improper treatment not only delays the condition, but also bring mental, economic, physical and other aspects of the burden on the patient. Long-term treatment will also aggravate the patient’s psychological pressure. If the patient is a middle-aged or elderly person, his or her physical quality is declining, and the trauma caused by surgery may not be able to get good results for the elderly.
