Specialist maxillofacial surgeons Tim Martin and Sat Parmar prepare for a marathon operation on 53-year-old Teresa. Four weeks ago, Teresa was diagnosed with a fast-growing cancerous tumour in her face and she will die within weeks unless it is removed. The procedure involves radical surgery to the entire right-hand side of her face, and means she will lose both her upper jaw and right eye. It is an enormous undertaking for Teresa, and for Tim and Sat, too. Using 3D imaging, the team plan how to remove the tumour and, most importantly, how they will rebuild Teresa's face. Tim and Sat are all too aware that whilst removing the tumour will save her life, it will be devastating if she is left disfigured and unable to face the world. To give her the best possible outcome, they intend to fill the cavity left in Teresa's face with a section of bone and muscle removed from her hip, using a 3D-printed plastic guide that helps them cut out the correct shape bone.
