Normal Anatomy and Anatomic Variants of the Paranasal Sinuses on Computed Tomography

Sanjay Vaid et al. Neuroimaging Clin N Am. 2015 Nov.

Abstract

It is imperative for all imaging specialists to be familiar with detailed multiplanar CT anatomy of the paranasal sinuses and adjacent structures. This article reviews the radiologically relevant embryology of this complex region and discusses the region-specific CT anatomy of the paranasal sinuses and surrounding structures. Radiologists also need to know the clinical implications of identifying preoperatively the numerous anatomic variations encountered in this region and prepare a structured report according to the expectations of the referring clinician.

Keywords: Anatomic variants; Anatomy; Clinical implications; Computed tomography (CT); Paranasal sinuses.
