Imaging Evaluation of the Paranasal Sinuses

Research output: Chapter in Book/Report/Conference proceedingChapter


Cross sectional imaging has revolutionized the way we approach anatomy and pathology of the paranasal sinus. Plain films, once considered standard of care, have been widely replaced by high-resolution computed tomography (CT) and magnetic resonance imaging (MRI). Both these modalities provide information that is essential for evaluation and treatment of various sinus pathologies. CT provides excellent detail of osseous anatomy while MRI provides superior soft tissue resolution. Both can help diagnose various benign and malignant paranasal disease processes and, as importantly, evaluate their extension into adjacent compartments, including the orbits and skull base, making them essential tools for surgical/treatment planning. Recently positron emission tomography (PET) was added to the imaging arsenal. It provides the physiologic aspect of paranasal sinus imaging. This modality is mostly reserved for staging and restaging of tumors and for differentiating post treatment changes from recurrent or residual disease. This chapter describes the three cross sectional imaging techniques, their advantages and limitations in evaluation of paranasal sinus anatomy and pathology. The chapter also provides a detailed description of the anatomy, normal variants, and critical variants as well as an overview of pathologies involving the paranasal sinuses.
