Left picture: Congenital facial paralysis on the right side in an 8-year-old boy. The smile is markedly disfigured by asymmetry. Right picture: A few weeks after free functional muscle transplantation, a symmetric smile on the formerly paralyzed right half of the face is already possible. The intelligent boy already uses his new muscle function "involuntarily" and has successfully integrated it unconsciously into the facial expression of the non-paralyzed left opposite side. A slight swelling on the right side will continue to decrease as he recovers from surgery. The danger of teasing at school should be averted by the successful reanimation of the formerly paralyzed half of the face.
