[[Orbital wall fractures in 3D computer tomographic imaging]

Assessment of diagnostic value of three-dimensional reconstruction of computerised tomography pictures was performed on 26 patients with compound fractures of orbital and craniofacial bony structures. There were carried out examinations in the patients in standard axial or frontal sections and then three-dimensional reconstructions were obtained with bony threshold. Rotational ability of the reconstructed picture was used by performing cranial rotations in any axis and at any angle. 3-D reconstructions have distinctly revealed bony fragments displaced towards the orbital lumen from the vault to the maxillary sinus in fractures of the fundus and depressions of the medial wall to the ethmoid. Compound fractures of orbital walls tightening the superior orbital fissure, canal of the optic nerve and the apical region have revealed reconstructions with cut off screening structures combined with rotations of the obtained picture. Manipulations with the picture reveals the dimension of spatial depth allowing the assessment of distance and showing the course of fissures of multiplanar fractures branching off towards the environment.
