Cone beam computed tomography for the nasal cavity and paranasal sinuses
1Department of Oral Pathology Medicine and Radiology, Indiana University School of Dentistry, 1121 West Michigan Street, Room S110b, Indianapolis, IN 46202, USA.
Abstract:
The paranasal sinuses are 4 paired airspaces that border the nasal cavity. Dental professionals are most familiar with the maxillary sinuses as viewed in 2-D imaging (eg, periapical, panoramic projections). With increasing implementation of 3-D imaging, specifically cone beam CT, there is a high probability that much or all of the paranasal sinuses and nasal cavity will be captured in a scan. It is incumbent on practitioners to be familiar with all the structures contained within a scanned area. The purpose of this article is to provide an overview of the anatomy of the nasal cavity as well as common anatomic variants and pathologic entities.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
