There are two types of facial palsy that occur after facial spasm surgery: facial nerve edema caused by adhesions between the detached blood vessels and the facial nerve, called early onset facial palsy, which occurs immediately after surgery; the second type is facial neuritis caused by cold and other factors, also known as late onset facial palsy, which occurs mostly within one month after surgery, with the most occurring around 2 weeks after surgery. No matter which of these two types of facial palsy, most of them have a chance to recover, and the recovery period is mostly within 3 months. After facial palsy occurs, the main measures include: 1. pay attention to warmth, rest, avoid straining and excessive alcohol consumption; 2. take prednisone tablets orally, usually one tablet three times a day for two weeks; 3. take vitamin B1 tablets orally, usually two tablets three times a day, and it is recommended to take them continuously until facial palsy recovers; 4. take Micropô tablets orally, usually one tablet three times a day, and it is recommended to take them continuously until facial palsy recovers.
