title: Best face forward: Virtual modeling and custom device fabrication to optimize craniofacial vascularized composite allotransplantation.
abstract: Craniofacial vascularized composite allotransplantation is especially challenging when bony components are required. Matching the complex three-dimensional anatomy of the donor and recipient craniofacial skeletons to optimize bony contact and dental occlusion is a time-consuming step in the operating room. Currently, few tools exist to facilitate this process. The authors describe the development of a virtual planning protocol and patient-specific device design to efficiently match the donor and recipient skeletal elements in craniofacial vascularized composite allotransplantation. The protocol was validated in a cadaveric transplant. This innovative planning method allows a "snap-fit" reconstruction using custom surgical guides while maintaining facial height and width and functional occlusion. Postoperative overlay technology in the virtual environment provides an objective outcome analysis.
