Trigeminal neuralgia is an acute pain in the trigeminal nerve area with unknown causes, also known as primary trigeminal neuralgia. At present, the clinical diagnosis of trigeminal neuralgia is mainly based on the clinical symptoms and signs of patients. The pain of trigeminal neuralgia is generally lightning-like, acupuncture-like, knife-like and paroxysmal, which can be induced or aggravated by eating, brushing teeth and talking. And it happens several times a day, lasting several seconds or minutes at a time. Generally, the most sensitive parts of trigeminal neuralgia are cheeks, corners of the mouth, alar and tongue. Under normal circumstances, patients with trigeminal neuralgia have no positive signs in nervous system examination.
For the treatment of facial trigeminal neuralgia, at present, the more mature clinical treatment methods are drug treatment and surgical treatment. Surgical treatment mainly includes radiofrequency thermocoagulation, craniotomy and gamma knife radiotherapy. At present, radiofrequency thermocoagulation is more respected and the effect is more obvious. Under the precise positioning of radio frequency, the radio frequency needle directly reaches the focus, only blocking the pain of the diseased nerve, and other feelings are still there, so that the diseased nerve no longer conducts pain.
Radio frequency thermocoagulation in pain department of Huanggu Central Hospital in Shenyang is the latest international technology, which can solve the problem of trigeminal neuralgia safely, efficiently and quickly, and the cost is lower than microvascular decompression and gamma knife. CT-guided radiofrequency thermocoagulation of trigeminal nerve was used to treat trigeminal neuralgia, and the effect was obvious.
