Facial expressions provide unique insight into a person’s emotions and are important for communication. The loss of facial expression can be a very upsetting condition, regardless of cause, duration, or age.

Facial paralysis occurs when there is loss of facial movement, and there are many causes of facial paralysis (more than 100!).  Some are present at birth (i.e. Mobius syndrome), some occur later in life, and facial paralysis may be unilateral (affecting one side of the face) or bilateral (affecting both sides).

Facial palsy is a complex condition. At St. Louis Children’s Hospital, we provide comprehensive care to children with facial paralysis through a multidisciplinary team approach. Initial consultation is often with the reconstructive surgeon, Dr. Alison Snyder-Warwick. Consultations with other teams may be beneficial including:

What are the Effects of Facial Paralysis?


  • Eye difficulties due to increased eye exposure. Eye irritation, excess tearing, blurred vision, corneal ulcers, and repeated infections may occur.
  • The affected eye may have a larger or staring appearance.
  • The affected portion of the face may droop, although this is less common in children.
  • In cases of paralysis on one side of the face (unilateral), the mouth is more crooked with smiling. The normal muscles pull the lips to the normal side with smiling.
