The fundaments of CBCT and its use for evaluation of paranasal sinuses: review of literature

ABSTRACT

Image methods such as Magnetic Resonance Imaging (MRI), Computed Tomography (CT) and Cone Beam Computed Tomography (CBCT) are powerful tools to help clinicians on diagnosis and preoperative planning. They provide an accurate view of regional anatomy, anatomical variations and the presence of diseases. Compared to CT, CBCT produces images with adequate spatial resolution with smaller fields of view at lower radiation doses. It has emerged as a potential alternative for obtaining 3D evaluation of the paranasal sinus at relatively modest costs. The aim of this review was to verify whether CBCT images offer an additional value to the evaluation of paranasal sinus
