To determine whether facial palsy is recovering, it is mainly based on the appearance, whether the affected side stores rice, the degree of disappearance of frontal lines and electromyography examination, as follows: 1. Appearance: The degree of recovery of facial palsy can be found by looking directly at the appearance. It is recommended that the patient should puff his cheeks and judge according to the change in the degree of air leakage. 2. Whether the affected side stores food: The degree of recovery of facial palsy can also be evaluated by whether the affected side stores food when eating and the degree of storage. 3. The degree of disappearance of frontal lines: If it is peripheral facial palsy, the degree of disappearance of frontal lines can also be evaluated according to the degree of disappearance of frontal lines. 4.Electromyography: The most authoritative test to determine whether facial palsy is recovering is still electromyography. Through the changes in conduction speed, the degree of recovery of facial palsy and the approximate time needed for recovery can be assessed.
