Abstract:
Medical treatment of facial paralysis sequel is an essential part of the overall management of this pathology. The use of botulinum toxin has revolutionized results in greatly improving facial symmetry. The toxin can be used either the healthy side of the face by treating the compensatory hyperactivity of non-paralyzed side of the face or the paralyzed side (in the spastic forms) to treat synkinesis and spasms of the face on the pathologic side. This treatment course will be complemented by the rest of the therapeutic, i.e. rehabilitation and surgical treatment.
