When walking on the street, you will often see such a group of people with uncontrollable eye or facial throbbing or twitching, and some patients also have twitching and crooked corners of the mouth. When such symptoms occur, they are likely to have facial myospasm. Facial muscle spasm mostly starts at the corners of the eyes and gradually expands to other parts of the face, with the corners of the mouth twitching to attract the most attention. In life, there are many patients with facial muscle spasms who are annoyed by involuntary facial twitching, and long-term recurring seizures cause great distress to patients’ life and work, and also increase the psychological burden. The facial myoclonus is more common after adulthood, around 40 years old, and generally occurs unilaterally on the face, and is very rare bilaterally. In addition, facial muscle spasm has the characteristics of recurrent and uncontrolled attacks, when the attack, the facial muscles will appear frequent and rapid twitching, less than a few seconds, more than a few minutes, after the patient’s emotional stability can reduce the symptoms. Mild facial muscle spasms can be temporarily relieved by medication. For poorly treated and severe facial muscle spasms, early surgical treatment is recommended. It has been found that the cause of most patients with facial myospasm in clinical practice is due to adhesions or entrapment of the nerves and blood vessels in the face due to certain factors, resulting in the inability of the nerves to maintain normal voluntary facial activity, thus causing episodic, recurrent, involuntary twitching of the facial muscles. In view of this, the medical community recommends the adoption of microvascular decompression for targeted treatment. What is the procedure for facial muscle spasm? With the advantage of microvascular decompression, the blood vessels closely related to the facial nerve are carefully searched for, the surrounding arachnoid is identified, the arachnoid is loosened, it is separated from the neurovascular, and a tefflon spacer of appropriate size is inserted between the vessel and the root of the facial nerve, and the facial muscle spasm is effectively resolved.
