Liu Linghui: Professor, doctor of medicine. He has been engaged in neurosurgery for more than 20 years and has a deep understanding of trigeminal neuralgia. He is the earliest member of the team to carry out radiofrequency thermocoagulation treatment of trigeminal neuralgia in China, and has thousands of treatment experiences. Visiting hours: Tuesday morning. Many patients went to neurosurgery because of repeated toothache, even after tooth extraction, but they were diagnosed as trigeminal neuralgia. After radiofrequency thermocoagulation, trigeminal neuralgia was relieved immediately. Trigeminal neuralgia is a common disease, with a prevalence rate as high as 50/65438+ 10,000 people. Its typical symptom is that when eating, washing face, brushing teeth, talking, or even walking vibration or wind blows to stimulate a certain point on the face or mouth, facial attacks and knife-like lightning-like pain occur immediately, each attack lasts for several seconds, and the elderly last for several minutes, with frequent attacks every day. The site of pain during the attack is actually one or several branches of the trigeminal nerve distribution area, or it can start from one branch and then spread to other branches, and the pain attacks are mostly distributed along the nerve direction. Patients with the above-mentioned manifestations should go to regular hospitals for specialized treatment in order to make a clear diagnosis and correct treatment. Radiofrequency thermocoagulation is used to treat trigeminal neuralgia by puncturing the semilunar ganglion with a puncture needle, generating electric heat in the tissue with a radio frequency instrument, and selectively destroying the pain-conducting fibers according to the different temperatures tolerated by different nerve fibers, thus achieving the analgesic effect. Has the following advantages: 1. Good analgesic effect and quick response. 2. Less complications and less risk, which can be tolerated by the elderly and infirm. 3. The tactile sensation of the affected side can be preserved. 4. It is suitable for all kinds of trigeminal neuralgia, and it is equally effective for all kinds of losers. It can be repeated many times until the effect is satisfactory. (Liu Linghui, Professor of Neurosurgery, First Affiliated Hospital of Jinan University)
