Botulinum toxin (Botox™) and Hyaluronic Acid Filler for Facial Paralysis or Synkinesis
Hyaluronic acid (HA) fillers are used for temporary volume augmentation of different areas of the face. Their use in the setting of facial paralysis is not FDA approved and is considered cosmetic. However, hyaluronic acid fillers can improve some of the symptoms of facial paralysis by improving the symmetry of the cheeks, lips, and other areas of the face. Likewise, botulinum toxin is helpful in treating unwanted facial movement in synkinesis. In the Video, a patient of Dr. Pepper’s discusses her experience with botulinum toxin and filler use for facial weakness and synkinesis.
How long do these treatments last?
In general, botulinum toxin treatments last for three months. Filler lasts between six months to two years, depending on the type, amount, and location of the filler injection.
