Radiology: Its Diagnostic Usefulness in Rhinosinusitis

  • Laurie A. LoevnerEmail author

This chapter addresses imaging modalities available to assess disease processes of the sinonasal cavity and provides some direction on when and how to use them. To understand the pathogenesis and imaging appearances of rhinosinusitis and other pathological processes that may affect the paranasal sinuses, a brief review of sinus development and anatomy as it pertains to mucociliary clearance is essential. Subsequently, focused imaging assessment of disease processes, including rhinosinusitis and neoplasms, is covered.


The maxillary sinuses are the first of the paranasal sinuses to develop, beginning in the first trimester of gestation and usually completed by adolescence [1]. The ethmoid air cells arise from numerous evaginations from the nasal cavity, beginning with the anterior air cells, and progressing to the posterior air cells. The ethmoid air cells start to develop between the end of the first trimester and the mid-second trimester of gestation, and their final adult...
