From time to time, we may see people with involuntary eyelid fluttering or involuntary twitching of facial muscles, which is likely to be suffering from a cranial nerve disorder called facial myoclonus. Facial myospasm is still very common in the clinic, the incidence is relatively high, and there are a large number of people suffering from it in the country. Facial muscle spasm mainly manifests as paroxysmal involuntary twitching of one side of the face. Initially, the degree of twitching is light, and later it will become more and more serious, the scope of twitching gradually expands, and the duration of the twitching will also gradually lengthen, ranging from a few seconds to several minutes or even ten minutes. This frequent onset of severe facial muscle twitching will cause great physical and mental torture to the patient, seriously affecting the patient’s normal work life and study, and also causing great mental and psychological torture to the patient. Some patients have even become depressed and suicidal because of this, with very terrible consequences. Therefore, patients suffering from facial spasm should seek regular treatment in a timely manner. Most ordinary patients or many local primary care hospitals tend to prefer conservative medical treatments, such as medication, acupuncture, closed therapy, botulinum toxin injections and so on, but these methods often do not achieve very satisfactory results, but only temporary relief of symptoms, and may also produce a lot of side effects, which may bring more harm to the body. The standard treatment for facial muscle spasm is now recognized by the medical community as microvascular decompression. When it comes to surgery, many patients may be more concerned about the cost and may ask how much it costs in total to have this facial muscle spasm surgery. Microvascular decompression surgery is a minimally invasive procedure that involves making a 3-5 cm incision behind the ear, carefully probing the vascular-neural anatomy around the facial nerve root, finding the responsible vessels that are compressing the facial nerve root, and relieving this abnormal compression to restore the normal function of the facial nerve, thus curing the disease with excellent results and at a low cost.
