Abstract:
It is imperative for all imaging specialists to be familiar with detailed multiplanar computed tomography imaging anatomy of the paranasal sinuses and adjacent structures. This article reviews, in brief, the radiologically relevant embryology of the sinonasal region and discusses the imaging anatomy of the nasal cavity and paranasal sinuses. Radiologists should understand the importance and clinical implications of identifying the numerous anatomic variations encountered in this region and prepare a structured report that provides a surgical road map to the referring clinician.

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...

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
