Drooping of half of the face may be caused by physiological factors, such as stimulation by cold wind, or pathological factors, such as peripheral facial paralysis, central facial paralysis and other diseases.
1. Physiological factors: Physiological factors that lead to half face drooping are mainly caused by cold, especially after the patient’s face is stimulated by cold wind, which will easily lead to poor blood circulation flow, and then the patient’s face will have a stiff feeling, and half face drooping feeling will appear.
2. Pathological factors
(1) Peripheral facial paralysis: The stiffness of the face caused by peripheral facial paralysis is due to the symptoms caused by viral infection of the facial nerve out of the cranium. In addition, after infection and inflammation, the patient will have obvious localized edema, which will compress the facial nerve, thus resulting in the phenomenon of myocardial paralysis.
(2) Central facial paralysis: central facial paralysis leads to facial stiffness and most of the chances are caused by intracranial diseases, especially when the patient has intracranial brain tumor, cerebral infarction and other diseases, the central nerves will be compressed to a certain extent, which induces paralysis of the facial muscles.
Half of the face can also be seen in other causes, if you exclude physiological factors, it is recommended to go to the hospital in a timely manner, to clarify the cause of the disease, and then follow the doctor’s instructions for treatment.
