What reason is left corner of the mouth twitch

summary

The initial symptom of hemifacial spasm is palpebral beat. I believe we all know that there is a saying that "the left eye jumps to wealth, the right eye jumps to disaster", so people generally don't care too much. Over time, it develops into hemifacial spasm, even to the corner of the mouth, and even the neck. The primary type of hemifacial spasm will occur in a static state, and it will be relieved after a few minutes without control; the hemifacial spasm caused by the sequelae of facial paralysis is only produced by blinking and raising eyebrows. So what causes facial spasm?

What reason is left corner of the mouth twitch

First: on the one hand, facial spasm is caused by pathological interference of facial nerve conduction caused by certain compression. Most patients are caused by normal cross compression of blood vessels. The causes of facial spasm include compression of posterior inferior cerebellar artery, anterior inferior cerebellar artery and vertebral nerve artery, and occasionally caused by aneurysm and arteriovenous malformation.

Second, another part of the patients may cause facial spasm because of the pathological changes of demyelination caused by facial neuritis. There is still partial demyelination, which makes the electric conduction of facial nerve easy to be caused by generalization, or facial neuritis involves the nerve nuclei in the brain stem, forming epileptic lesions and producing paroxysmal twitch of facial muscles.

Third: a very small number of patients with traumatic tumor or surgical operation after the onset of lateral muscle spasm. It may be that there is a short circuit between facial nerve and other brain nerves during the recovery of facial nerve. When other nerves are excited, one side of facial muscle twitches. All of the above can cause facial spasm.

matters needing attention

Patients with hemifacial spasm should take appropriate activities, strengthen physical exercise, often listen to light music, have a peaceful mood and get enough sleep. Patients with hemifacial spasm usually do not eat raw, cold, greasy, irritating, indigestible food.
