Trigeminal neuralgia is a neurological disease that occurs in the distribution area of the trigeminal nerve on one or both sides of the face, with painful symptoms such as discharge and cutting, which is unbearable for people. The incidence of trigeminal neuralgia is high, the age is mostly after 40 years old, and there are more women than men. The pain can be severe when talking, brushing teeth or when the breeze is blowing, and it can last for several seconds or minutes. After the onset of trigeminal neuralgia, patients have to suffer severe pain, which is unbearable. The longer the course of trigeminal neuralgia, the more the pain will expand, so timely treatment is needed to avoid aggravation of the condition. There are many causes of trigeminal neuralgia, especially in winter, many patients obviously feel the symptoms worsen, especially after the face is cold, such as cold water washing face will feel the symptoms tend to be severe. Patients with trigeminal neuralgia better not wash their faces with cold water because trigeminal neuralgia is a kind of neuropathic injury, and cold stimulation will make trigeminal neuralgia very sensitive and prone to occur. Therefore, trigeminal neuralgia patients, it is best to wash their faces with warm water to avoid letting their faces encounter cold. In addition, do not get angry or emotional, eat a light but nutritious diet, especially do not drink alcohol and smoke, which may cause blood vessels to dilate, thus compressing the trigeminal nerve and making it more painful. For patients with milder degrees, they can try some physical therapy, such as acupuncture and laser irradiation, heat therapy, etc. Microvascular decompression has been used to treat trigeminal neuralgia for more than 10 years, and the technique is quite mature, minimally invasive, safe and highly effective. Most patients can be cured after surgery, and the chance of complications is very low. It is currently recognized as the best treatment for trigeminal neuralgia at home and abroad. Moreover, patients with milder symptoms and shorter medical history often have better treatment results. Microvascular decompression can achieve a primary cure, even if there is a delayed cure, and often does not require continued oral medication to relieve symptoms. In most patients, the symptoms of spasticity disappear immediately after surgery. In only a few patients, a period of neurological recovery is required due to severe nerve damage, and symptoms gradually resolve during the recovery period.
