1.What are the main facial neurological diseases, what is their incidence, and what kind of people are more likely to get them? Facial neurological diseases mainly include facial muscle spasm and facial palsy. The incidence of facial nerve diseases in China is increasing year by year, and many people will have facial muscle spasm when they are overstressed and fatigued. Clinically, the incidence of facial spasm is higher in women than in men, with an annual incidence of about 2-3 per 100,000 in global statistics, and more in middle-aged and elderly people. Facial palsy, as it is known to the general public, occurs in young adults between the ages of 20 and 50, and is more common in men than in women. Pregnant women have a higher incidence than the general population, especially from 2 weeks before to 2 weeks after childbirth. The prevalence of diabetes mellitus is 4-5 times higher than that of the general population, and 7-10% of patients have a family history. 2. Are facial spasm and facial palsy the same thing? Facial palsy and facial muscle spasm are both problems of the facial nerve, but they are completely different diseases and are treated differently. Facial palsy refers to facial muscle paralysis, which is a condition caused by damage to the facial nerve for various reasons, mainly manifesting as dysfunction of the motor function of facial expression muscles, such as crooked mouth, inability to raise the eyebrows when making expressions, no forehead lines, incomplete eyelid closure, shallow nasolabial folds on the affected side, crooked mouth to the sound side, inability to puff, and leaky drinking. Facial myoclonus, on the other hand, is a paroxysmal involuntary twitching and jumping of the facial muscles, usually starting with involuntary jumping of the eyelids, progressing to the corners of the mouth, and in severe cases extending to the entire half of the face. If the symptoms persist for three months, the diagnosis of facial spasm is confirmed. In short, facial palsy is a dysfunction of facial muscle movement, and facial muscle spasm is a paroxysmal muscle twitching. 3. Is eyelid jumping a precursor of facial muscle spasm or facial palsy? Most of the eyelid jumping is due to fatigue, mental tension, emotional excitement, and involuntary jumping caused by irregularities in life, not facial muscle spasm. It should be suspected only if the jumping is continuous for more than three months and keeps getting worse, which will involve involuntary jumping of one eyelid, facial muscle and the corner of the mouth. Facial palsy is usually a symptom of facial injury caused by a viral infection, etc. It can cause inability to close the eyelid and skewing of the mouth to the opposite side; there is also traumatic facial palsy, injuries brought on by knife cuts, car accident injuries, and broken facial nerves. Therefore, eyelids jumping all the time is not necessarily a precursor of facial palsy. 4.How to prevent and treat facial muscle spasm? Facial muscle spasm is idiopathic and cannot be prevented. It is mainly due to arteriosclerosis of the blood vessels and neuropathy, causing a short circuit in the area of the nerves out of the brainstem, resulting in facial muscle spasm. At this time there is no way to prevent and control the occurrence of facial myoclonus, you can only observe, after three months of continuous jumping can be diagnosed as facial myoclonus. Once the facial spasm is diagnosed, the only fundamental treatment available is surgery. The effect of botulinum toxin can be maintained for three months to six months, but it is sure to recur and needs to be played again, repeatedly more than three times, which may cause permanent facial paralysis. Microvascular decompression surgery is the only curable method at present. Therefore, there are two options to treat facial spasm, one is not to treat it. One is to go to a regular hospital to receive minimally invasive surgical treatment, the cure rate can be up to is 98%. 5, what is the most fear of treating facial muscle spasm, and what are the adverse consequences of not treating it? It is recommended not to treat blindly. Because many hospitals and doctors do not understand this disease, they prescribe you a lot of drugs and spend a lot of money, but the result is ineffective or secondary, fearing that the facial muscle spasm is bad, buried wire, local botulinum toxin treatment are possible to cause peripheral facial palsy damage treatment, treating the symptoms but not the root cause. For patients with multiple organ failure and advanced age, facial spasm will not affect survival, but only the unpleasant face, eyelid fluttering and uncomfortable, which is usually tolerable and therefore surgery is not recommended. For some patients with affected tinnitus, hearing loss, or even with vertigo, it is recommended that they should receive surgery as early as possible, otherwise it may cause long-term vertigo, tinnitus, and hearing loss; facial myospasm may cause vision loss and facial deformity in the later stages.
