It is a common sense to take medicine if you are sick. However, there is a strange disease, the start of the disease does not hurt, not only the patient is not easy to detect, but also take medicine is not very useful. This inexplicable onset of disease, clinical medicine called “facial muscle spasm”. The patients of facial muscle spasm have this experience, the beginning of the feeling of eyelids jumping hard, eyes involuntarily blink ah blink. Originally thought to be a lack of rest, but later spread to the corners of the mouth, side of the face, chin, neck. When you get excited and angry, the twitching is even stronger. Facial muscle spasm is a special facial nerve disease, the main cause is because the blood vessels squeeze and compress the facial nerve root, resulting in abnormal facial nerve discharge, the facial muscles accept and make the twitch response. In the early stage of the disease, patients mostly choose the method of drug treatment. The twitching symptoms are relieved by taking oral sedative drugs. Although it has some effect, it will cause loss of facial nerve function and increase the burden on liver and kidney. Medication will only relieve the symptoms of convulsions, and the effect will get worse and worse, and cannot solve the problem at the root. For most people, medication has taken a detour, and microvascular decompression is the only way to cure facial spasm. Through the guidance of high-definition microscope, the microvascular decompression surgery can accurately find the blood vessels compressing the facial nerve among the intracranial tissues and gently push them away from the facial nerve root so that they no longer compress the facial nerve root.
