Facial bone structure has been effectively surgically changed since the publication of Dr. Paul Tessier's work in the early 1970's and his invention of Craniofacial Surgery.
The PROMINENCE of facial bones can be INCREASED by increasing their height with either facial implants or facial grafts or by cutting and advancing the bone. Bony prominences (IE Jay Leno chin etc) can be DECREASED by burring them down.
While applying cheek or chin implants may not be a highly demanding operation, increasing the depth of the eye sockets in a syndrome such as Crouzon's (Marty Feldman eyes - as in YOUNG FRANKENSTEIN) requires sawing a portion of the skull, advancing it forward and securing it in place with plates and screws is technically very demanding. So is the 3D surgical jig saw puzzle of putting together a face that was shattered in by the kick of a horse or a baseball bat.
