After the onset of trigeminal neuralgia, medication is the first choice of treatment. If the effect of medication is poor, surgical treatment can be considered. There are two methods of surgical treatment. One is radiofrequency treatment, which physically destroys the trigeminal nerve but often relapses after surgery.

The other method is microvascular decompression surgery of the trigeminal nerve under a microscope. This surgery requires craniotomy under general anesthesia. Under the microscope, the trigeminal nerve and the blood vessel pressing on it are identified, and then a special material is used to separate the two, so the blood vessel cannot irritate the trigeminal nerve, and thus, the pain is alleviated.
