How can I achieve better symmetry following an accident? (Photos)

Hi! Achieving symmetry after injury to the face is definitely possible. Have you had a recent CT scan? Was any reconstruction done using plating and screws for fractures? That will be important to determine to ensure the underlying bone (foundation) is good. Implants such as MedPor or silicone can be placed to create lasting improvement. Fillers can provide volume and improve contours though you may need quite a bit which is expensive. Fat transfer is a great option to get more long-lasting results. I would recommend consultation with a facial plastic surgeon familiar with reconstructive procedures. Hope this helps you!
