Facial stroke with a crooked mouth depends on whether the cause of the crooked mouth is due to peripheral facial palsy or central diseases such as cerebrovascular disease, cerebral infarction or cerebral hemorrhage. Patients with peripheral facial palsy, such as incomplete facial palsy, can usually recover or heal within 1-2 months. Patients with complete facial palsy take 2-8 months or even 1 year and often have sequelae. Younger patients recover better, while older patients with pain in the mastoid region or herpes in the external auditory canal or auricle, or with risk factors such as diabetes, hypertension, or arteriosclerosis, recover less well. The crookedness of the corners of the mouth caused by central facial palsy, such as cerebral hemorrhage or cerebral infarction depends on the size of the infarct or the amount of bleeding to determine how long the prognosis is.
