This is the horrific tumour 17-year-old Grace, from the Democratic Republic of Congo, had growing on her jaw bone.
But charity hospital Mercy Ships performed a four-hour surgery, removing the teen's tumour, lower jaw and teeth.
Parker cut away the huge lump and replaced Grace's jaw with titanium plates.
He told Barcroft Media: “When she heals six months from now she can have artificial teeth if she wants. That will help her with her chewing – appearance-wise and functionally she should be able to have a normal life.”
Brilliantly, Grace is now hoping to study medicine and pursue a career in nursing.
She said: "They made me happy – now I want to study and help other people. I would like to work on the Mercy Ship to help people for free, like they have done for me."
Grace's story will appear in a new series of Body Bizarre, which airs every Thursday at 9pm on TLC.
