What level of pain is trigeminal neuralgia? Trigeminal neuralgia is also known as the “No. 1 pain in the world”. The onset of pain is sudden and stops abruptly. It is a lightning-like, slashing, burning, persistent, unbearable and severe pain. How many levels of pain is trigeminal neuralgia? The World Health Organization classifies pain on a scale of 0 to 10. Among them, 0 is no pain, 10 is the most painful, 1~3 is mild pain, 4~6 is moderate pain, the pain is obvious and unbearable, 7~10 is severe pain, the pain is so intense that you cannot sleep, and trigeminal neuralgia is one of the 10 levels of severe pain, so you can imagine how terrible the pain is when it strikes. Talking, washing face, brushing teeth or breeze, or even walking can lead to severe pain when paroxysmal. This is due to the trigger point effect of trigeminal neuralgia, and once triggered, the pain may flare up. The pain lasts for a few seconds or minutes, and the pain comes in periodic episodes with the same intervals as normal. Therefore, we should give more care and understanding to trigeminal neuralgia patients in our daily life, and appreciate the difficulty they have when they have an attack. Encourage trigeminal neuralgia patients to receive treatment and recover as soon as possible, do not be anxious and depressed because of this disease, trigeminal neuralgia can be treated. Trigeminal neuralgia can be cured by conservative treatment with medication and surgery. Generally speaking, medications such as carbamazepine are preferred to relieve trigeminal neuralgia symptoms. However, as time goes by, the effect of the medicine will diminish and the treatment of trigeminal neuralgia will not be as effective. So only pre-treatment is recommended to relieve symptoms, and long-term medication is not recommended. Instead, the best treatment option is surgery. The procedure is called microvascular decompression. Trigeminal nerve microvascular decompression is the preferred surgical procedure for primary trigeminal neuralgia and is currently the only procedure that can cure trigeminal neuralgia radically. Under general anesthesia, a 4-6 cm incision is made behind the affected ear along the hairline, the skin and muscles are retracted to reveal the mastoid roots, and a 3 cm diameter bone window is drilled. The dura mater is cut and the cerebrospinal fluid is aspirated under the microscope, the arachnoid is cut and the trigeminal nerve root is explored, and the responsible vessels (one or more) that are compressing the trigeminal nerve root are found. (in case of compression by the rock vein, the rock vein must be dissected). The responsible vessel is freed by microdissection and then padded with a tefflon surface. The procedure is minimally invasive and has a good prognosis. It is the treatment of choice for trigeminal neuralgia.
