Facial trigeminal neuralgia, a “scary” disease that tortures people and makes them go crazy with heartbreaking pain, can only be allowed to run wild in the body without surgery, and cannot be cured well. However, many people think that trigeminal nerve surgery is very risky and are afraid of the after-effects, so they have not considered the idea of surgery. In fact, trigeminal neuralgia surgery is not as exaggerated as people think, and will not leave aftereffects. A large number of successful surgical cases can prove that trigeminal neuralgia can be cured by microvascular decompression surgery. Let’s see how to do the operation, first of all, the left side of the sigmoid sinus after the approach to the small bone window minimally invasive microvascular decompression surgery, then slowly release the cerebrospinal fluid, separation of the arachnoid membrane, the exposure of the face of the posterior group of cranial nerves, auditory nerves, and further exposure of the rock vein and the responsible blood vessels – the ipsilateral vertebral artery, and then the compression of the trigeminal nerve and displacement of the main culprits – tortuous ipsilateral vertebral artery, and then the vertebral artery of the medulla oblongata section of pads into the isolation of the material, the use of leverage principle! Using the principle of leverage, the pressure on the trigeminal nerve is reduced, and a seemingly painful procedure is easily accomplished. All the patient has to do before the surgery is to relax and leave the rest to the surgeon. After careful preoperative preparation, the doctor performed the microvascular decompression surgery under general anesthesia, and the patient was awake soon after the surgery, with immediate results and no side effects.
