How is primary trigeminal neuralgia diagnosed? Trigeminal neuralgia is divided into primary trigeminal neuralgia and secondary trigeminal neuralgia, and the pathogenesis of primary trigeminal neuralgia and secondary trigeminal neuralgia are different. Trigeminal neuralgia is classified as a cranial neurological disease, commonly known as “face pain” in the past, with a high incidence rate, mostly in middle-aged and elderly people after 40 years old. If not properly treated, the long-term pain often makes the patient unbearable. How to recognize primary trigeminal neuralgia? Primary trigeminal neuralgia usually has no signs before the attack, sudden onset, transient, severe pain, maintain a few seconds or minutes to stop, intermittent period is completely normal, with the passage of time, most patients seizures become more and more frequent, the pain duration is prolonged, and there are few self-healing. The pain is severe and is often described as knife-like, pinprick-like, electric shock-like, burning, or tearing pain. Pain attacks can be triggered by talking, washing, eating, brushing, vibration, cold stimulation, and emotional changes. There may be concomitant facial flushing, tearing, salivation, and runny eyes. Some patients have trigger points. A certain area of the facial trigeminal nerve distribution is particularly sensitive, and the slightest touch can cause a painful attack, which is called the “trigger point” or “trigger point”. To reduce the rate of misdiagnosis, it is recommended to visit a neurologist or neurosurgeon at a major hospital. It is important for patients and their families to identify, and proper identification does not delay the disease and reduces misdiagnosis. Trigeminal neuralgia is still very well recognized. These are the characteristics of typical trigeminal neuralgia. Generally, early administration of carbamazepine and oxcarbazepine has good effect and the pain can be completely reduced, but since patients need to take them for a long time, many patients stop using them because they cannot tolerate their side effects. If the effect of drug control is getting worse or there are obvious responsible vessels and nerves riding across, it is recommended to consider surgery as soon as possible. Primary trigeminal neuralgia is currently the treatment of choice for patients with primary trigeminal neuralgia, which can achieve complete cure. Primary trigeminal neuralgia does not show neurological signs, and various examinations cannot reveal any organic or functional lesions related to its pathogenesis. Surgery for trigeminal neuralgia facial spasm is an internationally recognized authoritative method for the treatment of trigeminal neuralgia. It has also received unanimous praise in China. The surgery is a procedure operated under a microscope, so it is also called microvascular decompression. Microvascular decompression is a surgical incision made under a microscope in the hairline behind the ear to release the pressure of blood vessels on the nerve root, restore the normal function of the trigeminal nerve, and make the pain disappear. The procedure has the advantages of short time, less bleeding, fewer complications, less pain and quicker results, and the whole procedure is performed under a microscope. The surgery has gradually matured and is widely used in the treatment of trigeminal neuralgia, facial spasm and other diseases. The clinical results are good, the surgery has a high cure rate and quick recovery, and is well received by patients.
