Emily Eccles, 15, from Sheffield, was left with just one centimetre of skin keeping her jaw attached to the rest of her head after the accident in August.
Consultant surgeon Ricardo Mohammed-Ali rebuilt her face using three titanium plates and more than 160 stitches.
Emily is now calling for him to receive a knighthood.
The teenager was out riding in Baslow, Derbyshire, with a friend and her family when the accident happened.
The horse was spooked by an exhaust popping on a car and galloped along a country path, but after her feet came out of the stirrups, she fell to one side and her head hit a wooden post.
