The proverbial eyelid jumping, which I believe most people have experienced, is mostly related to poor rest and nervousness, and can go away automatically in the short term. If it persists and even develops into twitching at the corners of the mouth, then it is likely to be a “facial spasm”. This is a disease that cannot be cured by itself. The typical manifestation is a twitching of half of the face from the corner of the eye to the corner of the mouth, which is obvious after stress, excitement or exertion. Severe cases even lead to persistent muscle spasms, resulting in difficulty in opening the eyes, or changes in facial appearance. The muscle twitches are painless and the patient is not abnormal during the interictal period. The course of the disease is usually long, often over a year or even several years. The diagnosis of typical facial muscle spasms is not difficult, but it needs to be differentiated from muscle twitches and habitual twitching behind facial paralysis. It is important to note that very few bilateral twitches can be seen clinically, but the two sides do not start at the same time and do not twitch at the same time. Facial muscle spasm is a functional neurological disorder, and the muscle twitching itself is not life-threatening. However, the psychological impact of the disease on patients is huge, for example, many patients involuntarily twitch when meeting strangers, thus creating low self-esteem, depression and anxiety, which seriously affects normal work life. The treatment of the disease is concerned with the root cause. Modern medical research shows that long-term compression of the facial nerve root by intracranial vessels, especially arterial vessels, causing local nerve demyelination or/and increased excitability of the facial nucleus accumbens, is the root cause of the onset of facial muscle spasm. Therefore, surgical removal of the responsible vessels from the facial nerve roots is the most fundamental means of treatment for facial myasthenia. The procedure is called microvascular decompression and is performed by making an incision in the hairline behind the ear, making a bone hole about 2 cm in diameter, and microscopically cushioning the vessel with a special material to achieve treatment. This procedure has become the internationally accepted treatment for facial spasm and is the only truly effective treatment. As the procedure has matured, the safety and efficiency of the procedure are very satisfactory. Of course, I can appreciate that many patients temporarily choose non-surgical treatments due to their fear of surgery. For example, Botox A is a local injection treatment. The mechanism is to artificially block the conduction of the facial nerve by drug injection. Although it can eliminate the symptoms of facial muscle spasm for a certain period of time, it is also difficult to avoid causing paralysis of the facial nerve. Returning to the cause mentioned earlier, this method does not solve the compression of the nerve by blood vessels. As for other treatment methods, such as acupuncture and oral medication, their effects can be imagined. The facial spasm is not a difficult disease and can be cured with the right treatment. In fact, it should also be our basic attitude towards the disease.
