There are many patients with facial muscle spasm have more or less heard of Botox as a treatment, there is always a question in your mind, that is, whether there will be any side effects of playing Botox, the next step is for me to answer the doubts in your mind. First of all, from the cause of facial muscle spasm: facial muscle spasm is a blood vessel compression to the facial nerve leading to abnormal nerve discharge and thus triggered facial beating, so the treatment of facial muscle spasm needs to start from the cause, to solve the problem of blood vessels and compressed nerve. The most effective treatment program for this disease is microvascular decompression surgery, which is performed under the microscope to return the responsible blood vessels compressing the facial nerve to their original position, decompress the facial nerve, and insert a medical spacer to isolate the cerebral blood vessels and facial nerve. This results in a therapeutic solution. Microvascular decompression is a similar minimally invasive surgery, not only can achieve the purpose of treating facial muscle spasm, but also the surgery is safe and reliable, it does not harm any nerve tissue of the patient’s face, it can maintain the integrity of the face and the functionality of the nerves, and the surgery is very efficient, so microvascular decompression is the best way to treat facial muscle spasm at present. Botulinum toxin is a kind of nerve-muscle joint blocker, through the nerve paralyzing function to block the conduction between the nerve endings and the muscles, prompting the muscles to relax and weaken the impulse transmitted from the nerves to the muscles, so as to reduce the twitching of the facial muscles and the feeling of discomfort. This method prevents facial twitching by sacrificing the motor function of facial muscles, so most patients can see the effect of Botox injection very quickly, but because Botox does not solve the root cause of facial muscle spasm (vascular compression), with the metabolism and absorption of Botox, the effect usually lasts for 3-6 months, and after a period of time it will be easy to relapse. After repeated injections of botulinum toxin, patients will gradually cause damage to the facial nerve leading to facial paralysis and facial deformity, which cannot be recovered, even if the future surgical treatment of facial muscle spasm, facial paralysis and facial deformity will still exist. Therefore, there are side effects of Botox in patients with facial muscle spasm, if you have facial muscle spasm, you must go to the regular hospital for examination and treatment, and remember not to blindly follow the doctor.
