Facial muscle spasm can be completely cured by surgery. First of all, the cause of facial muscle spasm is the facial nerve out of the brainstem area, there are blood vessels compressing the facial nerve, blood vessels on the facial nerve pulsating stimulation, will cause the facial nerve and facial nerve nucleus excitability increased, resulting in frequent “discharge”, a single discharge will lead to facial muscle twitching once, continuous discharge on the performance of facial muscle continuous twitching The facial spasm can be deformed. This indicates that the increased excitability of the facial nerve or facial nucleus is not controlled by the cerebral cortex, which supports the idea that the increased excitability of the facial nerve or facial nucleus is directly related to facial muscle spasm. Interestingly, a unique “abnormal electromyographic response” can be monitored during surgery in patients with facial muscle spasm when we use neuroelectrogenic monitoring technology. It was confirmed that the vascular compression was the cause of the abnormal EMG response and also the cause of facial muscle spasm. In the past, we used to judge the responsible vessel compressing the facial nerve by the surgeon’s experience; when there were multiple vessels compressing, we were worried about missing a certain vessel; when placing the spacer, we were worried that the spacer was too big or too small, or even slipped. Because the above conditions do directly affect the surgical efficacy, the lack of an objective evaluation index makes it difficult for even the most experienced surgeons to ensure the surgical efficacy, and some patients still have postoperative facial twitching, blaming it on delayed healing. In our experience, as long as the “abnormal electromyographic response” is removed intraoperatively, the patient will definitely be cured after surgery. Therefore, the etiology of facial spasm is clear, and through intraoperative neurophysiological monitoring, we can ensure that this etiology can be effectively resolved, and the theoretical cure rate of facial spasm can reach nearly 100%. At the same time, it is highly recommended that you choose a hospital and doctor experienced in facial myospasm surgery to operate, and intraoperative neurophysiological monitoring is highly recommended, which can guarantee the efficacy and safety of the surgery. You can get rid of the disease and regain your confidence!
