Facial muscle spasm is a common disease, more common in middle-aged and elderly people. It starts with involuntary twitching or jumping around the eyes, and gradually worsens, extending to the ipsilateral corner of the mouth and affecting the neck in severe cases. At the beginning of the disease, people generally do not care about it, and some people jokingly say “the left eye jumps for money and the right eye jumps for disaster”. Sometimes the twitching around the eyes is light and sometimes heavy, and sometimes it does not occur at all, as if it disappears by itself. However, as time passes, the number of twitches increases and the time without twitches decreases. The uncontrollable facial twitching occurs when talking, being emotionally tense, or when talking to people, causing them to be afraid to meet with people and even unwilling to go out. Many people think “it’s just a throbbing, it’s not painful”, but in fact, the facial nerve in charge of these twitching areas has been compressed, and the nerve will become paralyzed and lead to facial paralysis in the long run. At that time, even surgery will not be able to restore the end of facial paralysis. The current theory is that the twitching of the face is related to the compression of the facial nerve root, and the sclerosis and tortuosity of the blood vessels at the root of the facial nerve is the real culprit. We can see during surgery that some vessels are twisted into collaterals pressing on the facial nerve root, and some even press deep grooves into the facial nerve root. When these tortuous vessels are pushed out of the way, the patient’s facial twitching disappears after surgery and he can return to his normal life after a few days.
