Considering the fact that CBCT imaging has the strong potential to replace medical CT for some applications related to otolaryngology, there is a trend towards including specific ear, nose, and throat imaging programs in CBCT systems. High-resolution and almost artifact-free multi-planar reconstruction images that allow assessment of the precise intra-cochlear position of the electrode and visualization of each of the individual contacts make CBCT a perfect candidate for the postoperative assessment and follow-up of cochlear implantation electrodes (Ruivo et al. However, assessment of electrode position can be difficult with two-dimensional radiographs, especially in bilateral implantation where the implants superimpose each other on lateral views (Barker et al. In addition, postoperative imaging is highly suggested in order to confirm electrode placement, typically with plain digital or film radiographs especially in the ossified or congenitally abnormal cochlea due to increased chance of poor implantation. CBCT also revealed promising results for noninvasive intraoperative imaging to facilitate electrode array placement in the cochlea (Cushing et al. Owing to its significantly reduced radiation dose, CBCT is becoming the method of choice in the diagnosis and follow-up of some temporal bone pathology (Dahmani-Causse et al. CBCT provides reliable morphologic assessment of the temporal bone with higher spatial resolution compared to multislice computed tomography (MSCT). Applications have been extended to the face and skull base including the temporal bone. In comparison to traditional medical computed tomography (CT) systems, dental cone bean computed tomography (CBCT) units offer reduced effective radiation doses, shorter acquisition scan times, easier imaging, and lower costs. ![]()
