Trigeminal neuralgia is a common cranial neurological disorder with symptoms of severe and unbearable pain in the trigeminal region of one side of the face. The disease is most often seen in middle-aged and elderly people, with slightly more female patients than male. Since people are not familiar with trigeminal neuralgia, the probability of delayed and wrong treatment is high, so what are the characteristics of trigeminal neuralgia symptoms? 1, the pain is intermittent recurrent trigeminal neuralgia initial attack abruptly, the pain lasts for a few seconds or minutes, intermittent attacks, the interval between attacks is the same as normal, but in serious cases, there can be frequent attacks. 2.Severe pain The pain attack is described as knife-like, needle-like, lightning-like, burning-like intense and unbearable. Trigger points Trigger points, also called trigger points, are located on the affected side of the face, so patients may experience severe pain from talking, eating, washing face, brushing teeth, or even walking in the breeze. Trigeminal neuralgia is a cranial nerve disease. According to clinical findings, more than 90% of patients develop trigeminal neuralgia due to intracranial vascular compression of the trigeminal nerve roots such as the pontine brain, and some patients have secondary trigeminal neuralgia, which can be detected through medical history and some examinations. Trigeminal neuralgia usually does not heal on its own and will affect the physical and mental health, work and life of patients. Therefore, early detection and early diagnosis and treatment obtain better prognosis. Generally, trigeminal neuralgia is easily misdiagnosed as migraine and toothache, and patients are advised to consult neurology or surgery when the above three characteristics appear. After diagnosis, most patients have obvious effect when taking carbamazepine or oxcarbazepine drugs in early stage. When a small number of patients cannot tolerate the side effects of drugs and the effect of taking drugs is also ideal in severe patients, surgical treatment can be further considered. If the pain is caused by the compression of a nerve by a blood vessel, surgery is generally used to treat the pain with microvascular decompression. The surgery is performed through an opening behind the affected ear, and the responsible blood vessel and nerve are observed and identified under a microscope, then the two are carefully separated and decompression material is placed between them, so that the facial pain disappears after surgery and the purpose of cure is achieved without damaging the nerve and blood vessel, and the function of the facial nerve can be preserved.
