Patients with trigeminal neuralgia who have undergone nerve block treatment or radiofrequency ablation are most concerned about the effect. For secondary trigeminal neuralgia, the pain will gradually improve after the cause is removed. The more difficult type is the primary trigeminal neuralgia, which is famous in the pain world because the cause cannot be found. Therefore, the main principle of surgical treatment is to relieve the pain as much as possible. Generally, after surgical treatment, very obvious results can be seen, with more than 90％ patients not feeling pain anymore, and a few patients may not have immediate pain relief and get better in a few days. However, since the surgery does not address the underlying cause of the disease, some patients may be able to solve the problem forever with a single surgery, while others will be prone to recurrence of the condition. Almost half of them will experience a recurrence within 5 years, and the recurrence will have to be evaluated again for treatment. Among patients treated with radiofrequency ablation, the recurrence rate is somewhat lower due to the more precise surgical approach, with probably less than 3% recurring within 1 year after treatment and 10% to 20% recurring within 5 years. In addition to recurrence, some abnormalities may occur after surgery, such as numbness in the face and drooling. These conditions may be a reaction to anesthesia, or the trigeminal nerve may have been excessively damaged. This has to be observed for a period of time, and usually these conditions will ease as the anesthetic effect wears off, or as the nerve grows and repairs. Many people are concerned about whether the surgery will cause tinnitus, facial muscle spasm, or facial paralysis. In fact, the likelihood of these conditions occurring when treated by an experienced professional surgeon is very small. Moreover, most surgeries are minimally invasive, with an incision the size of a pinhole, so there is no need to worry about leaving scars on the face. There is no need to use hot towels after surgery; before the eye disappears, try to avoid getting the wound wet, and don’t wash your face with cold water.
