What is the difference between facial palsy and facial muscle spasm? In real life, some people often involuntarily tremble or shake their facial muscles, and the symptoms are more severe especially when they are nervous. Here, it is important to distinguish that facial neurological disorders mainly include facial muscle spasm and facial palsy. The symptoms of the two are somewhat similar, but they are not exactly the same, and the treatments are different, so you must pay attention to the distinction. The difference between the two Facial palsy refers to facial muscle paralysis, which is a condition caused by damage to the facial nerve for various reasons, mainly manifesting as dysfunction of facial expression muscle movement, such as crooked mouth, inability to raise eyebrows when making expressions, no forehead lines, incomplete eyelid closure, shallow nasolabial folds on the affected side, crooked mouth to the able-bodied side, inability to puff, drinking leakage and other symptoms. Facial myoclonus, on the other hand, is a paroxysmal involuntary twitching and jumping of the facial muscles, usually starting with involuntary jumping of the eyelids, progressing to the corners of the mouth, and in severe cases extending to the entire half of the face. If the symptoms persist for three months, the diagnosis of facial spasm is confirmed. In conclusion, facial palsy is a dysfunction of facial muscle movement, and facial muscle spasm is a paroxysmal twitching of the muscles. In some people, facial muscles tremble or shake in life, often involuntarily, especially during times of stress or important moments. Facial neurological disorders mainly include facial muscle spasm and facial palsy. The incidence of facial nerve disorders in China is increasing year by year, and many people experience facial muscle spasms when they are overly stressed or fatigued. Clinically, the incidence of facial spasm is higher in women than in men, and the familiar facial palsy is more common in young adults aged 20 to 50, and more in men than in women. It is mainly due to arteriosclerosis and neuropathy of the blood vessels, which cause short-circuiting of the nerves in the area of the brainstem, resulting in paroxysmal involuntary jumping of the unilateral eyelid and facial expression muscles. The treatment of facial muscle spasm should be examined and treated in a regular hospital, and should not be treated blindly. At present, microvascular decompression is the best treatment for facial muscle spasm. Microvascular decompression surgery for facial muscle spasm Microvascular decompression surgery refers to the magnification and re-operation of the intracranial nerve vessels through a high-powered microscope, placing a spacer between the nerve and the vessel, thus releasing the compression of the vessel on the root of the facial nerve, restoring the normal function of the facial nerve and relieving the symptoms of facial muscle twitching. This technique has the advantages of minimally invasive, high safety and low recurrence rate, especially it can completely preserve the function of blood vessels and nerves, which has become the most effective method for treating facial muscle spasm in the world, and it is the only way to completely cure facial muscle spasm.
