Evaluation of anatomical variations of nasal cavity and paranasal sinuses with cone beam computed tomography
(Nobelmedicus, 2017) Dedeoğlu N.; Altun O.; Bilge O.M.; Sümbüllü M.A.
Objective: The aim of this study is to evaluate anatomical variations of nasal cavity and paranasal sinuses using cone beam computed tomography (CBCT), which is currently used in dentistry radiology. 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 paranasal sinuses found in this study was agger nasi cell (95.6%). The most rarely observed variation was sphenoid sinus aplasia (0.8%). There was no statistically significant relationship between concha bullosa and nasal septum deviation. Conclusion: CBCT is a preferred alternative and reliable method for evaluation of anatomical variations of the nasal cavity and paranasal sinuses. © 2017, Nobelmedicus. All rights reserved.
