MICCAI 2022 Daily – Wednesday

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 the underlying bone structure will cause facial change. The challenge is how to model the facial tissue deformation efficiently and accurately when you move the bone. Deep Learning-based Facial Appearance Simulation Driven by Surgically Planned Craniomaxillofacial Bony Movement 4 DAILY MICCAI Wednesday Oral Presentation James Xia, MD (top left) is the Director of the Surgical Planning Laboratory at Houston Methodist Hospital and Professor of Oral and Maxillofacial Surgery. 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 speak to us ahead of Xi’s oral presentation this morning.
