Most facial palsy caused by cerebral infarction takes about 3-6 months to recover. The facial palsy caused by cerebral infarction is central facial palsy, which is manifested as paralysis of facial muscles below the eye fissure, and patients may experience symptoms such as shallowing of the nasolabial fold on the affected side and skewing of the corners of the mouth to the opposite side. Unlike the peripheral facial palsy caused by facial neuritis, the symptoms of central facial palsy are heavy and long-lasting, and its recovery requires the establishment of effective cerebral collateral circulation, which restores the function of central nerve cells. In addition, some medications can help the recovery of facial palsy, including neurotrophic drugs such as vitamin B1, vitamin B12, methylcobalamin, cytarabine, and drugs that promote the establishment of collateral circulation such as edaravone and butalbital, while rehabilitation training of facial muscles and Chinese massage, massage and acupuncture treatment can shorten the recovery time of facial palsy. Of course, in about 20% of cerebral infarction patients, facial palsy is difficult to recover and becomes a permanent sequela.
