Abstract
Current approaches for surgical correction of craniosynostosis are highly dependent on the experience of the surgeon and inaccuracies during cranial vault remodelling can compromise the surgical outcome. The objective of this study is the evaluation of a novel augmented reality system to guide surgeons during fronto-orbital advancement procedures. A smartphone software application was developed to overlay virtual models on the surgical field using augmented reality technology. Intraoperative markers and 3D photography are used to ensure accurate alignment between the virtual data and patient anatomy. The system was evaluated through simulations on patient-specific phantoms and the workflow was tested on two real surgeries. Results of this study demonstrate the accuracy of the AR visualisation to guide osteotomy and remodelling during fronto-orbital advancement. Feedback from 9 surgeons supports the integration of this technology on the surgical workflow for the treatment of craniosynostosis to accurately translate the virtual plan into the operating room.
