Source: Beijing Second Hospital understands trigeminal neuralgia, which is a necessary condition for trigeminal neuralgia control. Trigeminal neuralgia is paroxysmal severe pain that occurs in the distribution area of trigeminal nerve in patients' face. Trigeminal neuralgia can be divided into secondary and primary according to the etiology. Well, expert Li Xiaorong pointed out that the causes of trigeminal neuralgia are as follows: First, primary trigeminal neuralgia, the so-called primary is the real cause, so far it is difficult to find, some people think it is viral infection, others think it is arteriosclerosis. Recently, it has been found that trigeminal neuralgia is mainly of this type, and the treatment of primary trigeminal nerve is more difficult. Second, the physical examination of patients with primary trigeminal neuralgia showed no special findings in head plain film, head CT and MRI, while the physical examination of patients with secondary trigeminal neuralgia often showed abnormalities, such as hypoalgesia, masticatory muscle weakness, hearing impairment, unstable walking and other signs. Third, secondary trigeminal neuralgia, that is, trigeminal neuralgia, is caused by the stimulation and oppression of the lesions on the sensory pathway from trigeminal nerve to facial skin. Common diseases include trigeminal neurofibroma, cerebellopontine angle acoustic neuroma, meningioma, cholesteatoma, arachnoiditis of skull base, metastatic cancer, osteoma of skull, deformity, multiple sclerosis and trigeminal neuritis. Trigeminal neuralgia is very harmful to patients, and timely detection and treatment are the key. Beijing Jiaze Dong Bo Institute of Trigeminal Neurology has many authoritative experts in the research field and treatment methods of trigeminal neuralgia, and has efficient treatment technology. The latest technology of "painless intervention new therapy" can solve the intractable trigeminal neuralgia safely, efficiently, quickly and painlessly. It can be treated under the monitoring of images without damaging other nerves, thus ensuring the safety of patients during the treatment. As long as the diagnosis is made, this technique can be used for treatment. ? Experts say that finding out the cause of trigeminal neuralgia before treatment is the key. Only by finding out the cause can we prescribe the right medicine. Patients should be actively treated and must not delay their illness. Otherwise, the vicious circle will lead to other intractable diseases.
