Eye fluttering, paroxysmal involuntary twitching, uncontrollable, brief and rapid twitching, lasting for several seconds and then stopping automatically. The seizures are infrequent at the beginning, a few times a day, and gradually become more frequent as the disease progresses. This is the symptom of facial muscle spasm. With the advancement of medical technology, the treatment of facial myoclonus is also improving. Therefore, patients should pay attention to the most advanced and reliable surgical treatment, microvascular decompression, to remove the facial myoclonus while avoiding trauma. Many places in China are still using closure and drug injection methods to treat facial muscle spasms, which are dangerous. The blocking needle blocks the nerve conduction through the toxic effect of drugs on the nerve, which also destroys the normal nerve conduction while blocking the abnormal conduction, and facial paralysis occurs after the treatment, and the myospasm will appear again after the facial paralysis recovers, so it is impossible to cure completely. Many patients have permanent facial palsy due to repeated injections of drugs that cause irreversible damage to the facial nerve. This is something that Professor Wang Xuelian reminds patients to pay more attention to. Microvascular decompression, on the other hand, is a radical treatment for the cause of facial spasm, and is certainly much more effective than closed-needle, drug and acupuncture therapies. Most scholars and clinicians believe that facial myospasm is caused by compression of the facial nerve near the internal auditory meatus by a branch of the posterior inferior cerebellar artery: the symptoms appear when the vessel is overly tortuous, elongated and stretched or sclerotic. It is assumed that the myelin sheath of the facial nerve is atrophied at the site of compression and that the afferent sensory fibers “short-circuit” the efferent motor fibers, activating the motor fibers and causing facial muscle spasm. In other words, most of the facial nerve is compressed by crossed blood vessels, such as the posterior inferior cerebellar artery, anterior inferior cerebellar artery, vertebral nerve artery, etc. A few of them are related to compression of the facial nerve root by aneurysm, arteriovenous malformation or brain tumor, etc. According to research statistics, 80%-90% of patients with facial muscle spasm are caused by compression of the nerve by blood vessels. Microvascular decompression is the use of microsurgery techniques, intraoperative observation and careful identification of the responsible vessels that compress the nerve, and then the placement of decompression material between the vessel and the nerve, so as to achieve the disappearance of postoperative convulsions. Moreover, microvascular decompression is a minimally invasive surgery with small wounds that do not damage any nerve tissue of the face, preserving the integrity and functionality of the facial nerve, and is very safe.
