Trigeminal neuralgia, known as the “king of pain”, now has a definite treatment method in the medical field. This method is called “microvascular decompression”. Most trigeminal neuralgia is caused by the compression of nerves by blood vessels, resulting in recurrent severe pain in the trigeminal nerve distribution of the face. Microvascular decompression is to treat the root cause of trigeminal neuralgia. During the surgery, the responsible blood vessel for the trigeminal neuralgia is found, decompressed and moved to a normal area, and a medical pad made of special material is inserted to protect the trigeminal nerve from being compressed. Many patients have concerns about whether this type of trigeminal neuralgia microvascular decompression will be dangerous. Trigeminal neuralgia microvascular decompression is a minimally invasive procedure performed under a microscope, which is simple, technically mature and effective, and is effective in treating trigeminal neuralgia and hitting the lesion directly. Therefore, patients who are still suffering from trigeminal neuralgia should go to a regular hospital as soon as possible for treatment and early recovery.
