Facial myoclonus mostly occurs in patients after 40 years of age. The main manifestation of facial myoclonus is paroxysmal transient twitching of one eyelid, which gradually expands to the same side of the face, resulting in transient, paroxysmal twitching of one side of the face, which can lead to smaller eye fissures, distorted nose and crooked mouth in severe cases. The seizures are especially frequent during emotional excitement and exertion. Do not like to deal with strangers. Trigeminal neuralgia mostly occurs after the age of 40. Many patients visit the dentist for early onset of toothache and are diagnosed with trigeminal neuralgia after the so-called diseased teeth are extracted and the pain is still not relieved. The disease mainly manifests as a paroxysmal, lightning-like severe pain in one of the innervated areas of one side of the face (frontal and facial trigeminal nerve innervation area), which is painful in nature like cutting, stabbing and burning. The patient also has a clear trigger point, and the pain attack is triggered by combing the hair, washing the face, eating, talking, brushing the teeth, and radiates to the face in a lightning-like manner. There are more treatment methods for the above two diseases, such as oral carbamazepine, phenytoin sodium, local closure, perineural branch thermocoagulation, acupuncture, Chinese medicine, and gamma knife treatment is feasible for trigeminal neuralgia. But often the effect is very little, even if the symptoms are temporarily relieved, but soon the disease relapses again. The quality of life and work of patients are seriously affected. At present, the internationally recognized cure is nerve root microvascular decompression treatment. Theoretical basis: the cause of this type of disease is the facial nerve and trigeminal nerve out of the brainstem area has a clear alignment of abnormal blood vessels in the collaterals compression, through surgery to isolate the blood vessels, nerves, not to make contact between the two, can be cured of this type of disease. The surgery is minimally invasive and has a low impact on the patient, who can be discharged from the hospital in more than 10 days after the surgery if the recovery is smooth. It does not affect work life after discharge.
