Fork neuralgia is a well-known disease, commonly known as “face pain”, but its treatment is not well known, rather it should be the fundamental treatment method is not well known, the method is the following to say microvascular decompression, that is, minimally invasive craniotomy treatment method. Many patients or family members are frightened to hear about craniotomy, and they don’t even have the courage to do the surgery. In fact, this treatment method is very simple, and if the surgery is carried out smoothly, the damage is even smaller than trigeminal nerve avulsion, because this surgery does not cause any damage to the nerve, but separates the responsible blood vessel, which is the culprit of the pain, and no longer causes compression and stimulation to the trigeminal nerve. The surgical incision is located in the hairline behind the ear, about 5cm long, and the bone window of the skull is about the size of a coin. The whole operation process is completely under the microscope, which is very delicate, and there is almost no strain and damage to the brain tissue. The most important feature of this surgery is that the surgical damage is small, the postoperative recovery is fast, the recurrence rate is extremely low, there is no damaging operation on the nerves during the operation, and the patient retains completely normal facial sensation after the operation. At present, this surgical method is the only fundamental surgical method recognized at home and abroad for the treatment of trigeminal neuralgia.
