Facial palsy is a common disease, due to the lack of proper understanding of the disease, many people are very nervous after getting facial palsy and seek medical help everywhere, some people delay the disease due to the lack of proper treatment, making the disease persist and even leave sequelae, causing great obstacles and pain in psychological and physical aspects. The following is a brief introduction to the general knowledge of facial palsy, which is expected to be helpful to the majority of patients. Facial palsy, divided into peripheral facial palsy and central facial palsy. 1, peripheral facial palsy, also known as facial palsy or facial nerve paralysis, is a common disease. It is mainly characterized by incomplete closure of the unilateral eyes, inability to frown, skewed corners of the mouth, water leakage from gargling, and holding food in the mouth during meals. 2. Central facial palsy is a condition completely different from peripheral facial palsy, and is one of the sequelae of “stroke” (cerebral infarction or cerebral hemorrhage). “Stroke” is characterized by sudden fainting, distortion of one side of the mouth (eyes are normal), deviation and stiffness of the tongue, speech impairment, and weakness or even hemiparesis of one limb. Stroke and facial palsy are not the same concept, so we hope that patients should treat them differently to avoid unnecessary panic. Here we only introduce some general knowledge of peripheral facial palsy. Usually, people think that facial palsy only occurs in the elderly or develops in winter, but in fact, the disease can occur at any age and in any season. The onset of facial palsy usually occurs after a wind or cold, such as riding in a car into the wind or sleeping near an open window, and is often sudden. In addition, colds, otitis media, mumps, dental caries, etc. can also cause facial paralysis. The onset of facial palsy is often characterized by pain behind the ear, stagnation of the forehead, inability to frown, difficulty in closing the eyes, tearing of the eyes, inability to puff the cheeks and whistle, distorted corners of the mouth, and leakage of water from gargling. Depending on the site of facial nerve injury, numbness in the anterior 2/3 of the tongue, loss of taste and auditory hypersensitivity may also occur. Other patients may develop herpes in the auricle before and during the onset of the disease. This type is a more severe form of facial nerve palsy, which often takes a long time to treat and may also leave varying degrees of sequelae. Early detection and treatment play an important role in the outcome of this disease. If you find pain behind the ear, strong pain and discomfort in the neck, or numbness in the face, and distorted eyes and mouth after a cold or fatigue, you should go to a hospital in a timely manner to seek medical advice and treatment after a clear diagnosis, and you can usually be cured in a month or so if you are treated properly. The pathological changes of facial palsy are mainly facial nerve edema, high pressure in the facial nerve canal and different degrees of degeneration of nerve myelin or axons. The principle of treatment is to take immediate measures to improve local blood circulation, reduce the pressure in the facial nerve canal, eliminate edema and nourish the nerve, and at the same time, antiviral and antibacterial treatment should be used appropriately according to the blood test results to eliminate inflammation and avoid further damage to the facial nerve. Chinese medicine has unique therapeutic effects in treating this disease. A large number of clinical cases prove that the application of traditional Chinese medicine, acupuncture, water acupuncture, meridian massage, thermosensitive moxibustion, and early intervention of electromagnetic therapy can largely accelerate the healing process and prevent or reduce the occurrence of sequelae. In addition to the conventional treatment, the later conditioning is very important, among which the diet of facial palsy should be paid more attention. Avoid spicy, sour, dry, hard and rough foods. Second, eat more fresh vegetables, fruits, coarse grains, beans, fish. Calcium supplementation: Calcium is not only beneficial to bones and intelligence, but also promotes normal muscle and nerve function. As patients with facial nerve disease mainly suffer from muscle atrophy due to facial nerve conduction disorder, calcium supplementation is very important, and ribs, dark green vegetables, egg yolk, kelp, sesame, fruits, carrots and dairy products are all rich in calcium. Fourth, the appropriate increase in the intake of vitamin B: vitamin B can help the synthesis of nerve conduction substances, so it should be properly supplemented. Vitamin B is rich in the following foods: cilantro, tomatoes, winter melon, cucumber, papaya, apples, pineapples, pears, peaches, persimmons, grapes, etc.
