The aim of treatment of trigeminal neuralgia should be long-term analgesia. The methods of analgesia are divided into non-invasive and invasive treatment methods. Non-invasive treatment methods include medication, Chinese herbal acupuncture therapy and physiotherapy. They are suitable for patients with short duration of illness and mild pain. Invasive treatment methods include surgery, minimally invasive injection therapy and radiofrequency thermal coagulation therapy. Pharmacotherapy 1. Carbamazepine (carbamazepine) 2 times a day at the beginning, later 3 times a day. 0.2~0.6g per day, divided into 2~3 times, the extreme amount is 1.2g per day. 24~48h after taking the drug, there is analgesic effect. 2. Sodium phenytoin, also known as dilantin, has a large individual variation and is prone to drug toxicity, and blood concentration monitoring is required. The trigeminal nerve peripheral branch destruction treatment is divided into: supraorbital nerve block, infraorbital nerve block, posterior superior alveolar nerve block, maxillary nerve block, chin nerve block, inferior alveolar nerve block and mandibular nerve block according to the injection site. Minimally invasive interventional destruction treatment of trigeminal hemianopia The hemianopia is pierced into the cranial cavity through the oval hole and injected with glycerol, anhydrous ethanol, phenol solution, doxorubicin and other nerve-destroying drugs to block the 2nd, 3rd or even all three branches of the trigeminal nerve, which can obtain a prolonged blocking effect. It is used for the treatment of intractable trigeminal neuralgia, maxillofacial cancer pain and postherpetic pain of herpes zoster. Radiofrequency thermal coagulation therapy Radiofrequency thermal coagulation therapy uses high temperature to act on the ganglion, nerve trunk and nerve root to make their proteins coagulate and denature, thus blocking the conduction of nerve impulses. At present, radiofrequency thermal coagulation therapy is more widely used in clinical practice, and the therapeutic effect of thermal coagulation is good. V. Peripheral nerve avulsion VI. Balloon compression of the semilunar ganglion The balloon compression method is an international technique used for the treatment of trigeminal neuralgia since the eighties. The whole operation is carried out under X-ray screen. The success rate of the operation is about 90%, but the recurrence after six months is effective to be treated again, and the long-term effect is to be observed. VII. Trigeminal nerve root microvascular decompression Some clinical data also indicate that vascular compression of the trigeminal nerve is one of the causes of trigeminal neuralgia. Many scholars therefore use neurovascular decompression to treat trigeminal neuralgia. Gamma knife treatment of trigeminal neuralgia The principle of gamma knife analgesia is to focus gamma rays on pre-selected nerve clusters or nociceptive conduction pathways in the brain related to pain, a large dose of irradiation to destroy the nociceptive conduction pathways, blocking the conduction of nociception and achieve the analgesic effect. Gamma knife has also been used to treat trigeminal neuralgia with certain efficacy. The success rate of gamma knife treatment for trigeminal neuralgia is about 60%, and there is a possibility of recurrence.
