The pain in our body often makes us physically and mentally restless, and trigeminal neuralgia, a disease that is accompanied by severe pain, can bring great distress to our lives. So how to relieve the pain and treat trigeminal neuralgia completely? At present, it is the best treatment for trigeminal neuralgia recognized at home and abroad. And for patients with milder symptoms and shorter medical history, there are often better treatment results.” HIN was admitted to the hospital with the main cause of “paroxysmal pain on the left side of the face for more than 20 years, with progressive aggravation for 6 months.” The local clinic gave symptomatic treatment of “pain relief, acupuncture, closed needle” and so on, with general effect, and no further treatment was given. The pain worsened 6 months ago, with severe pain on the left side of the face, facial redness, swelling and burning, and the inability to wash his face and hair. The local hospital gave “carbamazepine” treatment, but still did not see significant improvement. In order to seek further treatment, the patient went to the neurosurgery department of the hospital and was admitted with the diagnosis of “trigeminal neuralgia”. The initial diagnosis was left-sided trigeminal neuralgia. After completing relevant examinations, Prof. Wang performed left-sided trigeminal nerve microvascular decompression under general anesthesia. Postoperative treatment was given to prevent infection, hemostasis, nerve nutrition and fluid replacement. After the operation, the patient’s left facial pain symptoms basically disappeared, and the pathological reflexes were not elicited. The wound was completely removed and the examination indicated that the patient’s condition was stable and could be discharged. Yin was unable to complete the simple movements of washing hair and face in daily life due to the influence of trigeminal neuralgia, and the basic daily life was greatly affected. After the treatment of apparent microvascular decompression, he recovered well and his face did not hurt anymore. The face that had been painful for more than 20 years was finally cured. “Epi-microvascular decompression can achieve a one-time cure, and even if there is a delayed cure, there is often no need to continue taking oral medication to relieve the symptoms. The symptoms of spasticity disappear immediately after surgery in most patients. In only a few patients, due to heavy nerve damage, a period of neurological recovery is required, and symptoms gradually resolve during the recovery period.
