title: A practical review of the muscles of facial mimicry with special emphasis on the superficial musculoaponeurotic system.
abstract: OBJECTIVE
  In this article, we elaborate a practical approach to superficial facial anatomy enabling easy identification of the facial mimic muscles by classifying them according to their shared common insertion sites.
  
  
  CONCLUSIONS
  The facial mimic muscles are often difficult to identify on imaging. By tracing them from their common group insertion sites back to their individual origins as well as understanding key anatomic relationships, radiologists can more accurately identify these muscles.
