What is trigeminal neuralgia? Trigeminal neuralgia is mainly manifested by transient, recurrent paroxysmal severe pain in the distribution area of the trigeminal nerve in the face. Symptoms: The pain may be electrical, stabbing, cutting or tearing on the affected side of the face. The pain usually does not go beyond the midline. Each attack may last from a few seconds to 1-2 minutes and then stop abruptly, with intervals as normal. The condition may gradually worsen and the number of pain attacks may become more frequent, even once a few minutes, resulting in more than one day. The pain can be triggered by touching the skin of the patient’s face. In severe cases, patients dare not wash their faces, brush their teeth or even chew, and rely on drinking a small amount of liquid or semi-liquid food to maintain nutrition throughout the day, which seriously affects the quality of life. Etiology of trigeminal neuralgia The etiology and pathogenesis of trigeminal neuralgia are still inconclusive, and trigeminal neuralgia is currently divided into two types: primary and secondary. 1, primary trigeminal neuralgia: the most common cause of pain is the trigeminal nerve microvascular compression theory, the main content of which is: the trigeminal nerve into the cerebral bridge section of the neural membrane is weak, if the long-term compression of blood vessels, demyelination may occur, resulting in biological current “short circuit”, causing pain attacks This results in a “short circuit” of bioelectric currents, causing painful episodes. This theory is supported by the good clinical results of trigeminal nerve microvascular subtraction. 2. Secondary trigeminal neuralgia: caused by tumors, cysts and vascular malformations around the trigeminal nerve that compress the nerve. What are the manifestations of trigeminal neuralgia 1. Pain: It is manifested as electric shock-like, pinprick-like, knife-like or tear-like pain on the affected side. The pain usually does not exceed the midline. Each attack can last from a few seconds to 1-2 minutes and then stop abruptly. During the interval, the condition can gradually worsen and the number of pain attacks becomes more frequent, or even one attack in a few minutes, resulting in more than one day. 2, pain trigger point: touching the skin somewhere on the patient’s face can trigger pain, serious patients dare not wash their faces, brush their teeth or even dare not chew, rely on drinking a small amount of liquid, semi-liquid food to maintain nutrition, seriously affecting the quality of life trigeminal neuralgia treatment methods 1, drug therapy: commonly used drugs for carbamazepine 2, closed treatment and radiofrequency thermal coagulation 3, gamma knife treatment 4, microvascular decompression surgery treatment Trigeminal neuralgia: it is the treatment method with the highest efficiency and cure rate, unless there are contraindications to surgery, otherwise it should be the first choice of treatment for trigeminal neuralgia. We adopt a minimally invasive micro-neurosurgery, through a bone window about the size of a dollar coin behind the ear, probe the root of the trigeminal nerve, find the blood vessel compressing the nerve, separate it from the nerve, and pad it with a Tefleon piece so that the two are separated forever. The advantage is the high rate of radical treatment and the preservation of three nerve functions, with our own statistics showing an efficiency of over 97%. Patients who are ineffective can be treated with partial trigeminal sensory root dissection.
