Three‐Dimensional Computed Imaging Using a Personal Computer for Nasal Surgery

Abstract

Three-dimensional (3-D) computed imaging was applied before surgery in 16 patients with nasal or paranasal disease. The images obtained by computed tomography (CT) were scanned by a personal computer. The contours of the organs were outlined on the scanned images, and the images were then reconstructed using 3-D imaging software. The resulting 3-D images were evaluated and compared with actual surgical images. The 3-D images were found to be useful for surgical procedures, because they facilitated recognition of the topologic relation between structure and lesion. Although this method requires a personal computer and an image scanner, it is cheaper than, and in some respects even superior to, a 3-D CT system.

Three-dimensional Imaging of the Internal Auditory Canal in Patients with Acoustic Neuroma

“…The clinical application of 3D imaging and its advantages have been reported in various fields (8)(9)(10)(11). In the present study, the shape of the IAC was assessed three-dimensionally, so these data are thought to be more accurate for investigating bone pathology.…”
