According to survey data, 20% of people who commit suicide in China choose to commit suicide because they cannot bear the severe pain caused by trigeminal neuralgia, which shows how much damage trigeminal neuralgia brings to patients. Trigeminal neuralgia patients have painful episodes that are limited to the area of the trigeminal nerve. The first branch of pain is above the corner of the eye, the forehead, and the eyebrow.

The second and third branches are more common in clinical practice, and the main symptoms are toothache and cheek pain. Occasional attacks of trigeminal neuralgia not only bring unbearable pain to the patient, but also make the patient’s mind suffer a great deal of torture and destruction. If not treated as early as possible, it will make patients nervous and depressed, and some even commit suicide. So, how to treat trigeminal neuralgia to protect yourself from further harm? Many patients have tried traditional methods such as medication, closure, and physical therapy, but found that they still do not help. The currently accepted medical concept of trigeminal neuralgia treatment is surgery, and microvascular decompression is an advanced technology that can effectively treat trigeminal neuralgia.
