The Difference Between Facial Spasm and Facial Paralysis

Facial spasm is a symptom characterized by involuntary and rhythmic contractions of facial muscles, usually starting with the tightening of the orbicularis oculi muscle. The twitching is typically confined to the eyelids or mouth. In severe cases, it can extend to the entire half of the face. Facial paralysis is a condition caused by facial nerve palsy, which can be either central or peripheral nervous system-related. The main clinical manifestations include inability to furrow the brows, squint, close the eyes, show teeth, drum fingers, or whistle. Facial spasm is not a precursor to facial paralysis, but it can be one of its symptoms. It is recommended to consult a hospital for examination and standardized treatment.
