Facial myoclonus: It is a paroxysmal involuntary twitching of facial expression muscles innervated by the facial nerve, mostly unilateral, slowly progressing, and rarely self-healing. The most common cause is vascular compression of the facial nerve root. The only way to cure it is to perform microvascular decompression of the facial nerve root. A small incision is made behind the ear, a bone window the size of a dollar coin is opened, and the blood vessels compressing the facial nerve are cushioned with a special material under a microscope to make it heal. Delayed facial paralysis: It is a type of transient complication after this surgery. The main cause is the local microvascular spasm after the surgery leading to abnormal blood supply, or the inflammatory reaction of the local virus after the surgery due to the decrease of its own resistance. It is mostly curable after giving simple treatment.
