Whether facial paralysis is serious or not depends mainly on the type of the disease. If it is peripheral facial paralysis, it is not considered serious, while central facial paralysis is more serious. 1. Peripheral facial paralysis: Peripheral facial paralysis is related to cold and other factors. Patients may have symptoms such as incomplete eye closure, tearing in the wind, and shallow nasolabial folds. However, the disease is self-healing, and most patients can recover between one and two months, with few sequelae. 2. Central facial paralysis: Due to the neurological deficits in the brain, the condition of patients is more serious than that of peripheral facial paralysis, and the recovery time is longer, and the possibility of after-effects is also higher. Therefore, for patients with facial paralysis, it is recommended to go to the hospital for head CT and other examinations in order to clarify the type of the disease and carry out treatment.
