There are various treatments for trigeminal neuralgia, which can be listed as follows: 1. Drug therapy (1) Carbamazepine (amidomiazine, Delidor), initially 100 mg, twice a day, and then increase 100 mg daily until the pain stops, with the maximum dose not exceeding 1200 mg/d, and then gradually reduce the dose to determine the minimum effective amount and take it as a maintenance dose. (2) Phenytoin sodium starts at 0.1g, 3 times/d; if it is ineffective, the dose can be increased by 0.1g daily, with the maximum amount not exceeding 0.6g/d. If toxic symptoms (such as dizziness, unstable walking, nystagmus, etc.) arise, the dose should be reduced until the toxic reaction disappears. If it is still effective, this is the maintenance amount. (3) Others, including phenobarbital and chlorpromazine, can be used in combination to improve the efficacy. There are still Chinese herbal medicines, such as seven-leaf lotus (wild papaya), made into injections and tablets. The injection is given 4ml each time, 2-3 times a day, intramuscularly. After the pain is relieved, it is changed to oral tablets, 3 tablets each time, 4 times a day, continuously. Sometimes combined with phenytoin sodium and carbamazepine can improve the efficacy. In addition, acupuncture, physical therapy and massage treatment may also have some effect. 2, closed treatment, including trigeminal nerve peripheral branch and hemimelia closed, the drugs used are anhydrous alcohol, hot water, quinine urea solution, vitamin B1, vitamin B12, etc.. This method is easy to operate, but the effect is not lasting, generally about six months that relapse. There are also certain risks, such as the possibility of serious complications such as hemorrhage, keratitis and blindness. Therefore, it is generally used for those who are ineffective in taking medication or are not suitable for surgical treatment. 3.Surgical treatment (1) Radiofrequency current percutaneous selective thermocoagulation can selectively destroy the nociceptive fibers of the trigeminal nerve, basically without damaging the tactile fibers. The method is simple and the complications are less. However, the recurrence rate is high, and it is mostly used for those who are old and frail or have other diseases and cannot tolerate open surgery. (2) Trigeminal nerve sensory root partial excision is performed by making an incision behind the ear, opening a small bone window, and microscopically cutting the nerve fibers of the trigeminal nerve that are in charge of nociception, while preserving the nerve fibers of facial touch and the nerve fibers that govern mouth chewing movement. After the surgery, there is no obvious abnormality in the facial appearance, but the face will feel a sense of wood. This procedure has good results and low recurrence rate. (3) Trigeminal nerve microvascular decompression, which is the most ideal procedure from the point of view of nerve function, is the treatment for the cause of the disease and preserves the function of the trigeminal nerve. (4) Other surgical methods such as trigeminal nerve peripheral branch aspiration, trigeminal spinal tract dissection and, in recent years, trigeminal ganglion balloon compression are still available, but these methods are less commonly used or have been eliminated. Note: At present, the preferred surgical method is apparent microvascular decompression, followed by trigeminal nerve sensory root partial excision.
