Inability to integrate surgical navigation systems into current surgical robot is one of the reasons for the lack of development of robotic endoscopic skull base surgery. We describe an experiment to adapt current technologies for real-time navigation during transoral robotic nasopharyngectomy. A cone-beam CT was performed with a robotic C-arm after the injecting contrast into common carotid artery. 3D reconstruction of the skull images with the internal carotid artery (ICA) highlighted red was projected on the console. Robotic nasopharyngectomy was then performed. Fluoroscopy was performed with the C-arm. Fluoroscopic image was then overlaid on the reconstructed skull image. The relationship of the robotic instruments with the bony landmarks and ICA could then been viewed in real-time, acting as a surgical navigation system. Navigation during robotic skull base surgery is feasible with available technologies and can increase the safety of robotic skull base surgery.
