We often see patients with trigeminal neuralgia in outpatient clinics, and the painful expressions cannot be hidden, and outsiders feel pain when they look at them. The pain attacks gradually become more frequent, and daily washing, brushing teeth, talking and eating can trigger pain, and life and work are difficult. Now Professor Wang will popularize trigeminal neuralgia for you, hoping that it can be detected and cured early. Trigeminal neuralgia is a common cranial neurological disease in middle-aged and elderly people. There are symmetrical trigeminal nerve distributions on both sides of the face, namely the ophthalmic branch, maxillary branch and mandibular branch. Most patients have no signs and symptoms, mostly pain on one side of the face, and rarely on both sides, starting with paroxysmal pain and gradually becoming frequent, which has a great impact on patients’ life. In terms of treatment, there are also some patients who make mistakes in early treatment because they do not know enough about this disease, and they can recognize trigeminal neuralgia from the following points. Severe pain: When the disease strikes, the pain is severe and described as electric shock, knife, needle, burning pain, which is unbearable, and some people even call trigeminal neuralgia “the world’s first pain”. Periodic attacks: The duration of trigeminal neuralgia attacks varies from a few minutes to ten minutes; the pain can disappear during the interval, and the interval is gradually shortened as the disease progresses; severe patients have frequent attacks. Most patients have more attacks during the day than at night, and a few patients have painful attacks regardless of day and night. Multiple trigger points: Trigeminal neuralgia has numerous trigger points with uneven distribution, mostly in the upper and lower lips, nose, nasolabial folds, dental bed, corners of the mouth, cheeks, tongue and eyebrows on the affected side; rarely in the jaw or outside the distribution area of the trigeminal nerve, such as the mastoid behind the ear and the frontal area. Predisposing factors: Patients can have pain attacks due to behavioral actions such as washing face, brushing teeth, talking, eating, laughing, and even sometimes yawning, stretching, walking; even natural stimuli such as breeze can cause pain attacks. If you have these symptoms, you can visit the neurology department to confirm the diagnosis of trigeminal neuralgia and treat it symptomatically. Generally, patients with mild symptoms can take carbamazepine or oxcarbazepine medication to get effective relief, a few patients cannot tolerate the side effects, and in severe patients, small doses may not be effective and large doses have high side effects. It is suggested that in severe patients, surgical treatment can be considered. Hospitalization for physical examination and examination of the cause, if it is due to compression of nerves and blood vessels, then consider the treatment of manifest microvascular decompression, which does not damage the nerves and can preserve the integrity of the facial nerves and can cure trigeminal neuralgia. If it is due to other causes, such as tumor-occupying compression, the appropriate treatment will be available.
