What causes facial muscle spasm? Most patients with facial muscle spasm are caused by normal vascular cross compression, such as compression of the facial nerve by the anterior inferior cerebellar artery, vertebral nerve artery, posterior inferior cerebellar artery, arteriovenous malformation, etc., resulting in abnormal facial nerve conduction, leading to paroxysmal spasm of the muscles it innervates. 2, a small number of patients with facial spasm may be caused by facial neuritis and other causes of nerve demyelination pathological changes have not returned to normal, there is part of the myelin sheath loss, resulting in the expansion of the electrical conduction of the facial nerve, causing similar facial muscle seizure twitching, thus triggering the occurrence of facial spasm. Occasionally, there are also brain tumors, aneurysms and other lesions that compress the facial nerve root. A very small number of patients with facial muscle spasms have facial muscle spasms after surgery or traumatic tumors. It may be related to the recovery process of facial nerve and other brain nerve short circuit, other brain nerve excitement will also appear when there is a side of the facial muscle twitching. 5, secondary facial muscle spasm refers to the existence of clear predisposing diseases, such as facial nerve trauma or facial neuritis caused by peripheral facial palsy, in the recovery period can cause facial muscle linked movement, characteristics similar to facial muscle spasm; some tumors or inflammation of the pontocerebellar angle involving the facial nerve root can also cause the occurrence of this disease. How to treat facial muscle spasm? Nowadays, the clinical treatment of facial myospasm is more often a direct surgical cure, which is called microvascular decompression. The procedure is called microvascular decompression, which is a treatment for facial myasthenia gravis and can completely cure the symptoms of facial myasthenia gravis. The procedure starts from the patient’s lesion and takes it down in one fell swoop so that the nerve is no longer compressed by the blood vessels. This will solve the problem of facial muscle spasm at its root. The surgery has been practiced for many years and the technique is very mature. The surgery has a high cure rate, low recurrence rate and few complications. It is the best method to treat facial spasm. Microvascular decompression refers to the magnification and reoperation of the intracranial nerve vessels through a high-powered microscope, placing a spacer between the nerve and the vessel, thus relieving the pressure 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 way to treat facial muscle spasm in the world, and it is the only way to completely cure facial muscle spasm. Here is a reminder that if you have symptoms in this area do not be anxious, facial muscle spasm is a benign disease, will not endanger the sick, timely hospital visits, it is possible to fully recover.
