A few questions about trigeminal neuralgia that are often asked by patients are as follows: 1. Trigeminal neuralgia is a neurological disease that occurs in the distribution area of the trigeminal nerve in the face and is as painful as a discharge or knife cut-like pain symptoms, which is unbearable for normal people. 2.What are the characteristic manifestations of trigeminal neuralgia? (1) Paroxysmal severe pain in the distribution area of the facial trigeminal nerve, lasting for several seconds to 1-2 minutes, with the same pain situation each time. (2) The pain can be caused by the movement of the mouth and tongue or external stimulation, and there is often a “trigger point”, which is painful when touched, mostly in the lips, nose, eyebrows and mouth, etc. For fear of causing attacks, patients often do not wash their faces, eat less so that their faces are dirty and they lose weight. (3) About 60% of patients have ipsilateral or bilateral eye tearing and drooling during painful attacks. Occasionally, there is an uncontrollable twitch of the facial expression muscle, called “painful twitch”. (4) The pain is periodic, and the painless period (a few days to a few years) is gradually shortened, and gradually and seriously affects eating and resting, so that the pain is unbearable, and self-healing is rare. 3.What are the surgical methods to treat primary trigeminal neuralgia? Microvascular decompression: Under general anesthesia, a 4-cm longitudinal incision is made behind the affected ear and within the hairline, and a hole is made in the skull with a diameter of about 2 cm, and the pontocerebellar angle area is entered under the microscope. Once the responsible vessels are isolated, the source of irritation disappears. Radiofrequency thermocoagulation of the trigeminal hemianopia: It is more suitable for elderly patients or patients who cannot tolerate the surgery. 4.What do trigeminal neuralgia patients need to pay attention to? Diet should be regular! It is advisable to choose soft and easy to chew food. Rinse your mouth, speak, brush your teeth and wash your face gently. Pay attention to the warmth of the head and face, avoid local freezing and dampness, do not use too cold or too hot water to wash the face; usually keep emotionally stable, should not be excited, should not stay up late with fatigue, often listen to soft music, calm mood, and keep enough sleep.
