Brushing your teeth would have been a trivial matter, but for Xiao Wu, who suffered from trigeminal neuralgia, part-time is a life and death experience. A few years ago Xiao Wu was diagnosed with trigeminal neuralgia, a pain that is unbearable even for a boy, who tasted unbearable pain and could not help but shed tears, which can be described as excruciating. Trigeminal neuralgia a typical pain characteristic, also known as trigger point, especially after being some kind of stimulation will appear violently. The onset of trigeminal neuralgia is often unpredictable, and the pain episodes are generally regular. Each pain attack lasts only a few seconds to a few minutes and stops abruptly. At the beginning of the disease, the number of attacks is small and the interval is long, ranging from several minutes to several hours, but as the disease develops, the attacks become more frequent, the interval is shortened, and the pain becomes more severe. The pain episodes decrease at night. There is no discomfort during the interval; triggering factors such as talking, eating, washing face, shaving, brushing teeth and wind can trigger painful attacks, resulting in the patient being depressed, acting cautiously, not even daring to wash face, brush teeth, eat and speak carefully for fear of causing an attack. Although trigeminal neuralgia does not affect a person’s life expectancy, it does have a great impact on the patient’s life and often makes the patient’s life unbearable. Here to remind the majority of patients if you meet such a disease must be clearly diagnosed, early intervention treatment. Radiofrequency technology has a good therapeutic effect on common clinical trigeminal neuralgia, cervicogenic headache, occipital neuralgia, intercostal neuralgia, postherpetic neuralgia, cervical spondylosis, lumbar leg pain, intervertebral disc herniation, myofasciitis, lower limb vasculitis, etc. Sanbo Brain Hospital of Capital Medical University has the international leading radiofrequency thermal coagulation technology, which can safely and efficiently solve trigeminal neuralgia. Radiofrequency thermal coagulation technology mainly uses foreign temperature-regulated radiofrequency advanced instruments, puncture under CT or DSA guidance, the needle tip does not damage other nerves, under superficial intravenous anesthesia, the needle tip directly to the lesion, acting on the root of the trigeminal nerve, so that the lesion nerve no longer transmits pain. The patient feels no pain during the whole treatment, and after the treatment will feel very light or no numbness of the skin mucosa at all, and the pain disappears. The technique has a high safety and low recurrence rate. Principle of radiofrequency thermocoagulation Radiofrequency thermocoagulation is a minimally invasive local thermal therapy technique. The radiofrequency instrument sends out high-frequency radioelectric current to produce an alternating electric field, which causes the water molecules around the electrode target tissue to oscillate and rub to generate heat. Using this principle, the temperature (42~98℃) and treatment time (1~3 minutes) are adjusted to act on different parts of the body to achieve the treatment purpose. Radiofrequency thermal coagulation inhibits the nociceptive fibers Aδ and C fibers that conduct pathological pain, while the fibers that conduct tactile and motor functions are preserved, thus blocking the transmission of pain signals to the spinal nerves and controlling pain. For the nucleus pulposus tissue in the herniated or bulging disc, radiofrequency thermal coagulation can cause ionic oscillation and heat generation, and the nucleus pulposus tissue will be shrunken by heat, the volume will be reduced, and the intravertebral disc pressure will be reduced, and the fascia around the disc will be tightened by heat to reduce or eliminate the pressure of the herniated tissue on the nerve root, so as to achieve the purpose of pain relief. Advantages of radiofrequency thermocoagulation 1, the procedure is less traumatic and less dangerous, and serious complications rarely occur 2, the temperature can be better monitored by the available thermocouple electrodes, and the temperature size can be effectively controlled 3, electrical stimulation positioning and electrical impedance monitoring can be performed 4, most radiofrequency thermocoagulation procedures can be performed under local anesthesia 5, the pain relief effect is good, eliminating pain and preserving the sense of touch 6, when needed, the treatment can be repeated.
