Abstract:
The nature and extent of congenital bony nasal obstruction is best determined by X-ray computed tomography (CT) imaging. Three-dimensional volume rendering of CT images provides an integrated perspective that can assist in clinical decision making and in operative planning. Clinical cases of choanal atresia and pyriform aperture stenosis are reviewed with their images. The authors propose this modality as an evolving standard for imaging of congenital bony nasal obstruction.

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...
