The treatment methods of trigeminal neuralgia include the following three aspects: 1, drug treatment: such as carbamazepine, which can relieve symptoms for a short time and improve patients’ quality of life, but it has large side effects; 2, injection treatment: such as stellate ganglion injection treatment, which can temporarily relieve symptoms with a short maintenance time; 3, microvascular decompression: the majority of patients’ pain disappears immediately after surgery without side effects and does not affect the quality of life, which is currently the preferred surgical treatment method for trigeminal neuralgia.
