Facial muscle spasm, commonly known as “crooked mouth wind”, is prone to squinting, and facial paralysis is a completely different disease, and the treatment is also different. So how do you tell the difference between the two? Is facial paralysis a facial muscle spasm? Facial paralysis and facial muscle spasm are both problems of the facial nerve, but they are completely different diseases, and the treatment is also different. Facial paralysis refers to paralysis of the facial muscles, a lesion caused by damage to the facial nerve due to various reasons, which is mainly manifested by motor disorders of the facial expression muscles, such as a crooked mouth, inability to raise the eyebrows when making expressions, absence of frontal lines, incomplete eyelid closure, shallow nasolabial sulcus on the affected side, a crooked mouth to the sound side, inability to puff up the air, and leakage of water for drinking, among other symptoms. The vast majority of patients with facial paralysis slowly get better with oral nutritional medications. Facial spasm, on the other hand, is a paroxysmal involuntary muscle twitching and throbbing of the facial muscles, usually starting with involuntary throbbing of the eyelids, progressing to the corners of the mouth, and in severe cases extending to the entire half of the face. If symptoms persist for three months, a diagnosis of facial muscle spasm is made. In short, facial palsy is a motor dysfunction of the facial muscles and facial spasm is a paroxysmal twitching of the muscles. What are the typical symptoms of facial muscle spasm 1, frequent blinking: the vast majority of patients occur unilaterally, and occasionally bilateral situations occur. 2, persistent eye jumping: the facial nerve is stimulated by vascular compression, the two muscles are excited at the same time, there will be repeated contraction, or even spasm or tremor, the eyelids will be involuntarily jumping. 3.Facial twitching: It is mainly the abnormal impulse of zygomatic branch facial nerve which dominates the facial muscle movement causing frequent facial twitching. 4. Twitching at the corners of the mouth: it is mainly caused by the abnormal impulse of the buccal branch of the facial nerve, which innervates the movement of the facial muscles, and the corners of the mouth are frequently twitching or crooked, and the neck and shoulder muscles can be involved in severe cases. 5, other symptoms: a few patients in convulsions accompanied by mild pain in the face (known as convulsive pain), individual patients can also be accompanied by headache, tinnitus on the sick side, deafness. Some patients due to long-term convulsions can appear on the side of the muscle weakness, atrophy and loss of taste in the front 2/3 of the tongue. At present, there are many ways to treat facial muscle spasm, it is recommended that patients timely to the facial nerve specialist, if the disease is not treated for a long time there will be long-term seizures, can not be self-healing.
