Computed tomography (CT) is the current imaging standard for the evaluation of rhinosinusitis because of its exquisite ability to display and differentiate hypertrophic mucosa, bone, and air. Multi detector (multislice) computed tomography scanners are readily available in most imaging centers and provide a quick and comprehensive evaluation of rhinosinusitis. On the other hands flat-panel-based cone-beam computed tomography (CBCT) is a recently deployed technology that potentially decreases radiation dose approximately 50% to 70% compared with multi detector (multislice) CT. CBCT allows for relatively good resolution of bony structures in the maxillofacial area; however, it has poor soft tissue contrast. CBCT has limitation in soft tissue imaging but the fine imaging in bone structure as MDCT. In this paper the utility of CBCT in rhinosinusitis is described.
