Preoperative Planning Using 3D Reconstructions and Virtual Endoscopy for Location of the Frontal Sinus

Abstract

Objective: Demonstrate the production of 3D reconstructions from CTs of patients and compare them to the surgery’s actual endoscopic images. Method: Prospective study. The CTs files of 10 patients were reconstructed with a specific program. The reconstructions were performed before the surgeries, and a virtual endoscopy was made. The actual endoscopic images of the recess and frontal sinus region were compared to the virtual images. Results: The 3D reconstruction and virtual endoscopy were made in 10 patients submitted to the surgery. The virtual images had a large resemblance with the actual surgical images. Conclusion: With relatively simple tools and a personal computer, we demonstrated the possibility to generate 3D reconstructions and virtual endoscopies.
