Daeseung Kim (bottom left) works for James Xia as an Instructor at Houston Methodist Hospital Research Institute. Pingkun Yan (top right) is an Associate Professor in the Department of Biomedical Engineering at Rensselaer Polytechnic Institute. Xi Fang (bottom right) is a PhD student in Dr. Yan’s lab. Their paper proposes a new deep-learning method for simulating facial appearance change following bony movement. Together, they spoke to us ahead of Xi’s oral presentation. Orthognathic surgery is a bony surgical procedure designed to correct jaw deformities by aligning the upper and lower jaw . The surgery can help people in several ways, including those with an underbite or overbite or those suffering from sleep apnea, where the upper and lower jaws are advanced to enlarge airspace. Although the facial soft tissue is not directly operated on, changing theunderlyingbone structurewill cause facial change. The challenge is how to model the facial tissue deformation efficiently and accurately when you move the bone. “When you start moving the bones, you do not know how the facial soft tissue is going to react,” James tells us. “We can use our artistic imagination and say, if I advance the upper jaw a DEEP LEARNING-BASED FACIAL APPEARANCE SIMULATION DRIVEN BY SURGICALLY PLANNED CRANIOMAXILLOFACIAL BONY MOVEMENT James Xia Daeseung Kim Pingkun Yan Xi Fang BEST O MICCA YOUNG SCIENTIST AWARD FROMMICCAI!
