Facial palsy is divided into central facial palsy and peripheral facial palsy. How long it takes for facial palsy to heal depends on the cause of facial palsy and the patient’s own recovery situation. The common causes of facial palsy are facial neuritis, tumor, cerebral infarction, facial surgery, etc. 1. Facial palsy caused by facial neuritis: the recovery period is about 3 months, and young people and patients who respond well to treatment recover in about 2 weeks. Most patients recover within 3 months after antiviral therapy, hormone therapy or neurotrophic therapy, and if they do not recover in more than 3 months, there is a possibility of sequelae; 2. Facial palsy caused by tumor or cerebral infarction: it is generally central facial palsy, and this situation depends on whether the patient’s primary disease can be well controlled, for example, if cerebral infarction is not effectively controlled, then facial palsy caused by cerebral infarction will generally leave For example, if cerebral infarction is not effectively controlled, then facial palsy caused by cerebral infarction usually leaves certain sequelae and cannot be fully recovered; 3. Facial palsy caused after facial surgery: If the trauma is caused by surgery, the patient’s facial palsy usually will not be fully recovered. Generally, if the cause of the patient is facial neuritis and he/she comes to the doctor just after facial palsy occurs, he/she can take hormonal drugs appropriately according to the doctor’s suggestion, and can also choose acupuncture treatment or Chinese herbal medicine treatment, and after regular treatment, he/she will usually be cured within half a month or one month. However, if the condition is delayed or improperly treated, the course of the disease may be longer.
