Whether trigeminal neuralgia is easy to treat must be judged based on the situation at the time. The vast majority of patients with trigeminal nerve pain can find a corresponding cause, such as compression by blood vessels, tumors, or infection factors. For vascular compression, microvascular decompression surgery can be adopted for treatment. For tumor compression, craniotomy and tumor resection can be adopted for treatment. For some infectious factors, treatment such as anti-infection and hormones can be adopted. These are relatively easier to treat, and most can have a very obvious prognosis. However, there are also cases, such as trigeminal neuralgia where no specific cause has been found, called primary trigeminal neuralgia, where active complete treatment is not possible, and only certain methods can be used to alleviate the general symptoms of the patient and reduce their suffering.
