Evaluation of Anatomical Variations of Nasal Cavity and Paranasal Sinuses with Cone Beam Computed Tomography
Material and Method: In this study, 251 patients’ nasal cavities and paranasal sinuses were evaluated using CBCT (Newtom 5G, Verona Italy) images in terms of anatomical variations. The high-resolution (voxel and slice thickness: 0.2 mm) multiplanar reformatting images (MPR) were used for the evaluation of the variations. Results: The most common anatomical variation of nasal cavity and paranasa...

متن کامل[Virtual endoscopy of the nasal cavity and the paranasal sinuses with computerized tomography. Anatomical study].
INTRODUCTION Virtual endoscopy is a new 3D technique which permits to depict the inner surface of anatomic cavities. We report our experience in the study of the nasal cavity and paranasal sinuses. MATERIAL AND METHODS CT examinations of the maxillofacial region were obtained using 1.5 or 3.0 mm slices, 1.5 or 3.0 mm table feed, 120 kV, 140 mA, 2 s scan time, standard and high resolution algo...
