CLIENT

Dr. David E. Morris, assistant professor and surgeon of the Division of Plastic, Reconstructive, and Cosmetic Surgery at University of Chicago, at Illinois

OVERVIEW

The Le Fort I osteotomy is a type of facial reconstructive surgery to help treat misalignment of the teeth. By surgically manipulating parts of the frontal skull, a surgeon is able to re-establish normal anatomy of the jaw and function to a patient’s airways.

THE PROBLEM

Maxillary osteotomies are performed in an extremely vascular region, where bleeding control is often not possible until the procedure is completed. As with many surgical procedures, complications at various stages can arise. An understanding of the anatomy helps prevent blood loss during the surgical procedure. The lack of visual references representing arterial vasculature for this area of surgery calls for the creation of a visual aid that will help educational aspects of this procedure.

THE SOLUTION

A 3D surgical animation was created to help facilitate learning the anatomy of the area of surgery. The main focus of the animation was created to teach how to navigate the osteotomy steps (see list below) safely and also to help surgeons visualize anatomical areas that they normally cannot see during surgery. 

 


 

MY PROCESS

See more images below for an insight into how the above animation was made.

MODELlING THE SKULL

A CT scan of the patient's head was exported as an .obj file from Mimics and brought into Maya. A simplified polygonal mesh was then created along the surface of the model. 

MODELLING THE INSTRUMENTS

As part of the creation process, photographs of instruments next to measuring tape were taken with a digital camera. The instruments were created from simple geometric cubes and cylinders in Maya. Using the grid as a guide (2 squares = 1 cm) these measurements were translated to each model. 

MODElLING AND RIGGING THE HANDS

The hand was modelled to act as the surgeon’s hand. A basic skeleton rig with IK handles, was then created for the hand. This rig allowed controls for animating parts of the hand model.
