AbstractA retrospective research was performed in order to evaluate three-dimensional (3D) computer-assisted detection of penetrating foreign bodies (FB) in the ENT practice in order to assess its usefulness and to specify its application. FBs in the head and neck were detected using 3D CT imaging in order to assess the usefulness of 3D images in the ENT operative practice. Three blinded surgeons were involved in comparison between plain and 3D CT images in order to assess 3D usefulness for precise formulation of a surgical plan. The observed relationship of the FBs to anatomical structures of the ethmoidal sinuses, eye orbit, and neck tissues was found instrumental for surgeon's decision making in planning the approach to operative removal of the FB. It helps to understand the relationships between a FB and surrounding anatomical structures better then the plain X-rays or CT-scan. There was no significant difference in cost between plain CT and 3D images. 3D computer-assisted detection of FBs increase our diagnostic abilities and appears to be a valuable addition to our diagnostic technique. Its main importance, however, lies in its capacity to help a surgeon plan an operation much more carefully avoiding improvisation during the operation itself.
