Complex Orbital Reconstruction
Abstract
1. The number and severity of battlefield injuries to the craniofacial region increased significantly with the operations in Iraq and Afghanistan as has the survival of personnel with hemifacial injuries after ballistic trauma. Non-battlefield craniofacial injuries, including blunt trauma from motor vehicle accidents and falls, also provide a significant challenge in military operations and are relevant to the general population. Because of the complex nature of these injuries and the location in the craniofacial region, multiple tissue types suffer damage. These defects often involve a loss of maxillary and periorbital architecture resulting in poor malar projection, orbital dystopia, and visual sequelae. These craniofacial injuries often require numerous sequential complex surgeries that often do not achieve adequate aesthetic restoration or functional recovery. Therefore, there is a critical need for new solutions and improved surgical methods to treat these injuries. 2. This work will deliver GMP grade scaffolds comprised of human bone extracellular matrix (ECM) blended with polycaprolactone (PCL) into hybrid ECM-PCL scaffolds that can be 3D-printed into precise anatomical structures and effectively integrated with the patients' stromal vascular fraction cells for the treatment of geometrically complex bone defects in craniofacial trauma, focusing on the periorbital regions. This single distinct technology developed during Grant W81XWH-11-2-0022 will be integrated for this complex reconstruction of hard (bone) tissues in periorbital defects.
