Trigeminal neuralgia is a neurological disorder characterized by paroxysmal and severe pain in the face, with a high incidence in the population, mostly in women, commonly in middle-aged and elderly people, accounting for about 70-80% of patients over 40 years of age. Since the pain is quite intense and unbearable, most patients often have a vivid memory of the time of the initial onset. As the name implies, the trigeminal nerve is divided into three branches, with the corners of the eyes and mouth as the boundary to innervate three areas of the face, clinically known as the trigeminal nerve distribution area. The symptoms of trigeminal neuralgia are very typical, mainly manifested as paroxysmal pain in the trigeminal nerve distribution area on one side of the face, the nature of the pain resembles a knife cut, electric shock, tearing or pinprick, sudden onset and sudden stop, in a cyclic attack, each attack lasts for a few seconds to 1 to 2 minutes, and the pain disappears naturally during the interval between attacks or during sleep. In daily life, eating, brushing teeth, talking, washing face, etc. can easily trigger painful episodes, and touching certain parts of the face such as the nasal area, perioral area, gums or eyebrow arch can also cause pain, these sensitive areas are called “trigger points” or “trigger points”, so patients Sometimes patients are afraid to wash their faces, speak loudly, or even eat in order to avoid painful attacks. Trigeminal neuralgia itself has no tendency to heal itself, and as the course of the disease lengthens, the number of pain attacks will gradually increase and the intervals will gradually shorten, even accompanied by facial numbness. Patients often rub the same side of the face with their hands during painful episodes, and over time the facial skin becomes rough, thickened, and eyebrows fall off, while the patient often looks thin, emaciated, unkempt, depressed and nervous due to the fear of eating and washing, which seriously affects the quality of life. Patients with trigeminal neuralgia often have typical onset characteristics, and a clear diagnosis can be made based on clinical manifestations. Modern medical research has found that, except for a small number of trigeminal neuralgia caused by secondary factors such as tumors and vascular disease, the majority of trigeminal neuralgia is primary, and is currently thought to be mainly due to the compression of the intracranial trigeminal nerve root by blood vessels. There are many treatment methods for trigeminal neuralgia, and the traditional treatment methods mainly include medication (antiepileptic drugs such as carbamazepine), trigeminal nerve peripheral branch closure, trigeminal nerve hemimelia radiofrequency destruction, trigeminal nerve rhizotomy and gamma knife treatment. Drug treatment can only provide early relief, and the dose of drugs needs to be increased as the disease progresses, which also increases the toxic side effects of drugs. All of the above traditional surgical treatments are destructive procedures, which can easily lead to facial numbness, keratitis and other complications, and the efficacy is maintained for a short period of time. The development of modern medical technology has provided new means for the treatment of trigeminal neuralgia. For the cause of trigeminal neuralgia, i.e. vascular compression, a minimally invasive method of microneurosurgery is used to release the vascular compression, and the recent and long-term efficiency has been significantly improved, and this surgical method is clinically known as microvascular decompression. At present, microvascular decompression has gradually become the preferred method for the treatment of trigeminal neuralgia, especially in Europe and the United States, which is characterized by small surgical trauma and precise efficacy. However, a comprehensive evaluation by a neurosurgeon specializing in neurosurgery, such as the patient’s age, clinical morbidity characteristics, and imaging examination (trigeminal nerve magnetic resonance tomography angiography) results, is required before the operation, which can help improve the effect of minimally invasive surgical treatment.
