statistical shape model (SSM)

Current craniomaxillofacial (CMF) surgical planning techniques that rely on cephalometric analysis work reasonably well in correcting mild jaw deformities, but are inadequate for complex CMF defects (e.g., trauma). To alleviate this problem, we propose a method for estimating patient-specific reference bony shape models for planning of reconstructive surgery for patients with acquired CMF defects. Experimental results show that our method is capable of effectively recovering the patient’s normal facial bony shape in regions with defects, allowing CMF surgical planning to be performed accurately for a wider range of defects caused by trauma. read more
