3D visualisation of the middle ear and adjacent structures using reconstructed multi-slice CT datasets, correlating 3D images and virtual endoscopy to the 2D cross-sectional images
Three-dimensional (3D) surface renderings were obtained from routine axial computed tomographic (CT) images in 15 patients with a variety of complex temporal bone abnormalities. The 3D CT reformations served as an adjunct to conventional sectional CT examination. While no diagnosis was substantially changed because of the 3D CT images, they did provide a more global perspective in cases of large tumors and fractures and at the postmastoidectomy site. Three-dimensional CT surface reformations are now practical and may be potentially useful for visualizing temporal bone lesions characterized by complex destructive change.
