Facial muscle spasm is an acute seizure symptom that not only brings great physical torture to patients, but also some patients do not know when the next convulsion is, always nervous, scared, and under great mental stress, and in the long run, mental discomfort and physical and mental devastation. The initial oral anti-epileptic drugs such as carbamazepine can relieve the symptoms of convulsions, but if taken for a long time, the drugs will play a smaller and smaller role, and if the drugs are taken for a long time, they will also increase the metabolic burden of the body. For patients whose medication does not work and whose convulsions are severe, surgery is the obvious choice. Experts here remind: patients must be careful when choosing surgical treatment. The reason is that some surgical operations are complicated, risky and incomplete, and although the symptoms of convulsions will improve somewhat after treatment, the condition will often recur after a while. Microvascular decompression is the latest treatment for facial muscle spasm, but many patients know little about it and dare not use it blindly. So what is microvascular decompression? Microvascular decompression refers to the surgical microscopic removal of blood vessels located in the roots of cranial nerves such as facial nerve and trigeminal nerve, which are abnormal and cause compression to the cranial nerves, thus eliminating the clinical symptoms. Compared with traditional treatment methods, microvascular decompression has outstanding advantages: 1. The most fundamental cause of facial muscle spasm and trigeminal neuralgia is cranial nerve compression, so the key to treatment is to release vascular compression and restore nerve function. Microvascular decompression surgery can solve this problem, directly targeting the cause of the disease, and the treatment is complete. 2.Traditional surgical treatment is traumatic to the patient’s body, while microvascular decompression is treated by minimally invasive surgery, which is the least traumatic to the patient’s body. 3, many patients take drug treatment, drug treatment toxic side effects, patients often have drowsiness, stomach discomfort and other symptoms after treatment, while microvascular decompression treatment without toxic side effects, patients will not produce uncomfortable symptoms after treatment. 4.Compared with traditional surgery, microvascular decompression is less risky and safer. In addition to the release of local vascular compression, the facial nerve sensory conduction is preserved intact and there is no loss of facial sensation. 5. The treatment course of microvascular decompression surgery is short and effective, and the clinical treatment of patients confirms that the symptoms of muscle spasm and trigeminal neuralgia improve significantly after treatment, and the condition improves.
