Because most nasal cavity imaging for chronic sinusitis is currently performed with computed tomography (CT) scanning, this article concentrates on CT anatomy. Understanding the anatomy of the nasal cavity and its anomalies is important because it leads to an understanding of imaging anatomy, which is needed to plan the surgical approach. Common anatomic variations are also discussed. Readers are urged to review anatomic texts before reading this article.
